Hey all,

I've recently launched a tool to help bring real world engineering principles into the simulator world.

Often I see people ask for tunes for certain cars on the forum, while this is a good starting point the purpose of the tune is to balance the car to your driving style. If you are taking someone else's tune, unless they drive exactly like you, your not going to be as fast as you could be.

The tool I've created allows you to see the results of adjustments made to the car for example, if you increase your spring rate and do not increase your dampers you are changing more than one parameter (spring rate, and damping ratio) although you physically only made one change. My tool helps you see the effect on the car as a system when you make an adjustment. This was you can balance the car in a way that makes sense to you.

Our club RWB racing have been using this tool and I have to say it's a great bit of kit!

Support Chargers opinion.

Been using this tool to set up my BMW TC for our league, and the Tire Setup tool alone transformed the car for me.

Can strongly reccommend this tool, for all struggling a bit with the understanding of Dampening, and tire temps/pressures.

Cheers RWB Audi

I've been fiddling with it, I'm hoping I'm on the right track. Since I'm currently using the Nissan GT-R GT3 in career mode I tried to come up with a set of numbers. Testing won't happen until much later today, does this look right to those that have used it?

Hey velvet, that looks like a good start. Your damping ratios look in range the car type, as well as your natural frequency. I would encourage you to try the setup and keep the two things described below in mind.

1) You have a fairly stiff spring setup, if you notice the car is very twitchy on controls try reducing the springs. I myself like the road cars around 3 Hz (natural frequency)

2) if you notice the car has oversteer issues, I'd first look at your differential, I've noticed on some cars the locking is to great on default and both power and ramp need to be increased (reduced locking) if your differential is all the way open then I'd decrease your rear spring, right now your sitting at 8% the lower you go the more likely to understeer the higher you go the more likely to oversteer.

Overall I think the setup should be a great start! If you have any questions or need more help please feel free to contact me via racingsimtools.com chat, as those go tm straight to my phone.

Spring bias to the rear by 10% will give you a fair bit oversteer on most GT3 cars. I usually run 10-15% front bias. NSX, 488 with 8-10% front bias. M6, AMG with ~15% front. You might face the same problem with the gtr. Maybe soften the rear springs if that’s the case.

Personally I run much stiffer damping too. ~75% average.

VelvetTorpedo
28-03-2018, 04:05
It does get tail happy now and again, always catchable but still more time to be gained. I'm definitely going to evolve the setup and dial what I can. Those spring rates were more to get the curves to sync the soonest than for spring balance. Have to experiment :cool:

Hi,

I purchased the tool as it looks very promising. However, I do struggle with the car I am currently using in PC2, the Ginetta G55 GT4.
The car does not have Fast Bump nor Fast Rebound. Please see the picture below, the stats are based on the standard stable setup.
In the "Low Speed" tab I do not get any graph at all. What values do I have to put in into the fields where the car does not provide any values?

Unfortunately I am not allowed to post a link, so there's a blank in the https:

Hi,

something's wrong. I tested the tool by putting inthe values in the above example (on two different WIN10 PC's) and the outcome compared to the picture above is completely different. I installed the file as an administrator.

Please kindly see here (there's a blank in the https):

Good point, thank you (now even the high speed graph is gone...).

However, there seems to be something completely wrong. Installed the tool on an old Vista, but same issue (do not get to the results of the picture above).

Not sure what's the issue?

racing_10tacle
29-03-2018, 17:28
Ok, presumably an issue with the Weight Bias? It shows 36.9 Hz Front and 40,26 Hz Rear instead of 3.69 an 4.03. Does that help?

Hi,

that's what I call dedication - Zach was available in the chat immediately and also was able to sort it out on the fly.
In case I got it correctly it was because in the EU we use a comma instead of a point in calculating values, so my calculation was corrupt and therefore the result(s) did not make any sense.

So Zach re-coded a EU version for me - great, thank you and much appreciated! Will test the tool the next days and report my findings here.

Thanks and best regards,

Awesome, I'm glad you guys are enjoying the tool, and my support. I try to help out the best I can, definitely learned something new with the whole local culture setting hehe, velvet, I'm guessing you liked that tune?? It felt really good when I did the video.

VelvetTorpedo
29-03-2018, 22:57
Yeah I made some diff changes and a few others, give my version a shot if you'd like. The stability is crazy.

Zeratall
29-03-2018, 23:15
Nice, I will definitely try it. Yeah during the tune video. I forgot to go back and tune the differential, like I said in the video I like to tune the suspension with the diff fully open that way I can feel the effects of the suspension adjustments by themselves. Normally I go back and dial in the differential after I'm happy.

I'm glad you enjoyed it, if you need more help or advice let me know, pretty much all I do now a days is tune cars lol.

It looks like the inputs are off, see how flat the blue line is? It shouldn't look like that, I know one of the variables steering lock can be bugged for some if the wheel callibration is off, what car are you try to analyze and what are your inputs for steering lock, wheel base, and steering ratio?

Just to be clear, when I mentioned "PC" I was referring to Windows based PC as widely referred. I'm assuming that's what you meant too right?....That the app to be installed is "PC" compatible and not compatible with a Mac computer right?

I used 10 for steering lock, wheel base 2.25 and ratio of 450 (i assume this relates to the wheel i am using) and the car was the Ginetta G40

I have also uploaded the csv (its not a zip - just delete the zip extension)

I will have another try tonight

Zeratall
04-04-2018, 18:53
Yeah those aren't right so for the ginett I believe the steering lock is about 110 degrees, steering ratio is the number in the tune settings I think most cars are anywhere from 11-14, and then wheel base. Looks good,

Try these settings (wheel lock 110, steering ratio 12, wheelbase 2.25)

Zeratall
04-04-2018, 18:55
Steering lock is the amount of rotation the steering wheel in game will rotate to one side, so what I do, is in my car ill turn the wheel all the way to left and see how many degrees it rotated from nuetral, most cars will go anywhere from 90 to 180 degrees. It'd the ingame steering wheel rotation not your physic wheel rotation. Which is why it can bug out if you the calibration is off.

Just checking these and the steering ratio for the G40 is from 4.5 to 27 and I am at 12 - we are talking about the ratio on the suspension screen?

Steering lock is 360 either way turning in game wheel one way and not 110 but even using 110 or 360 I still get e graph pretty much as previous - flat blue line and orange below the line where i am understeering and above where it is oversteering

Loaded your file, and I got this, which looks correct, you had good turn in performance but you were definitely getting some oversteer in the corner, see how you have counter steer in the turn.

You turn your steer wheel back out of the turn but you continue to have lateral acceleration acceleration in the turn, which is indicative of oversteer. 252592

Thanks and I will have anotherattempt tomorrow with the data and see what results I get .

Can you clarify the steering lock as you say 110 but as I said previously if I sit in car on track and go to full lock of the car steering wheel I am moving my wheel 360 degrees either way, so how come you say 110?

I appreciate you understand the information that the graphs show but are you able to mark up the screenshot to highlight the points you made such as good turn in performance, oversteer in the corner, counter steer in the turn, turn your steer wheel back out of the turn, lateral acceleration acceleration in the turn - this would really help myself and others who need a little guidance in interpreting the information

The track/car combo is one that I am trying to improve my TT time on as I am loosing the time with the cornering issues and fully understanding what the graph is telling me is the key for this car as the tuning options are minimal so it will come down to how I approach/exit the corners. I can see this in the way I can improve the times - but not consistantly and I am hoping that by undestanding the information from the graph I can adapt my driving style

Thank you for your input and patience

Zeratall
05-04-2018, 08:23
If you look at the image below, this is the G40, as you can see the steering wheel is fully locked out the left, it rotated from the vertical line to the line thats at approximatly the 8 o clock position. The total travel was approximately 110 degrees. Not sure how you were getting 360 degrees of rotation, but it sounds like a bug.

252616

as far as the graph goes, if you look at my blog I have a really detailed article on how to interpet this graphs at the link below. If you are still unsure or have questions let me know =). If you contact me via the website web chat it comes straight to my phone so we can have a a one on one chat where I can explain everything in detail. Or reach me on discord at "RWB/SRO Zeraxx#2602"

Many thanks

I did read your blog and the reason I was getting confused is that in your software you use "Blue" as steering input and on the blog "blue" is the neutral steer - so reading the explanation on the blog and viewing my graph - the little old human brain was getting confused as they are reversed.

So of to have a good study of this over next few days and will get back to you

Thanks again

Aaah I didnt even think about it, im currently investigating this calibration thing and hopefully I can tell you whats going on. I think I may have found the issue in the cal process. I can mark up the one you posted if you would like.

VelvetTorpedo
05-04-2018, 14:44
inthebagbud, is your wheel rotation set to 720, and rotating half of that to lock gives you the 360? My instinct was to put 450 there since I use 900 wheel rotation but I must have misunderstood.

inthebagbud
05-04-2018, 15:03
inthebagbud, is your wheel rotation set to 720, and rotating half of that to lock gives you the 360? My instinct was to put 450 there since I use 900 wheel rotation but I must have misunderstood.

That is what my instinct is - I use DOR of 900 on wheel but with the in car steering ratio I use this worked out at 720 to physically turn the car wheel to full lock, hence the 360. So when i sit on track I look at the steering widget at bottom left turn my wheel (controller) until the marker turns all the way either left or right and use this as the steering lock.

It occurred to me looking at the post by Zeratall is that he is measuring this manually by the wheel (in car) and I wondered if although we are turning the wheel (controller) 360 or 450 either way - how much the wheel (in car) actually moved and whether this was the confusion - however I seem to remember that this should not be the case and that wheel movement (controller) should be matched by car wheel - subject to my next sentence

The extra thing to consider is that wheel matching wheel only occurs if the wheel DOR (controller) is left at 900 or Auto and you change the in car ratio - if I remember correctly if you change your wheel DOR to less than 900 your wheel movement (controller) will not match exactly the wheel movement in car. BUT it has been a while since that topic was discussed and the cloud of time would need shaking off to fully confirm in PC2

I need to further review which will be in a day or so

Zeratall
05-04-2018, 15:12
So I think I may know the problem, its due to the calibration process. I think I may have screwed up my calibration process in game. So the cal process has 2 steps, step 1)turn full lock, then step 2) says "Turn the wheel 90 degrees".

My interpretation is to turn full lock and then 90 degrees opposite direction of full lock, however some of the guys have mentioned that its 90 degrees from neutral, I'm going to attempt to recal and if it results in different results then I'll fix the program, as it would only work for my inputs lol.

So the whole purpose of needing to know steering lock is because to calculate the neutral steer channel, I need to measure the steering angle of the tires themselves. I'm doing this by measuring the ingame wheel, then using the steering ratio to determine the amount of rotation of steering wheel to tire.

VelvetTorpedo
05-04-2018, 15:19
If I'm remembering correctly, when i do it I turn the wheel full lock to get the steering range to 100, then I turn the wheel until the blue number is about 900.

Go to the Time Trial for Watkins Glen in the RSR, filter the leader boards by "Vehicle" and find my ghost "Zeratall" try the setup my ghost uses, ive been told its one of the best setups people have tried. I will be able to upload it here once I'm done reinstalling the game, for some reason the latest patch broke my game haha.

Looking at your setup it depends, is this for a race setup or for TT, if its a TT our tires start out at ideal temperature, so we can get away with really low damping and more rebound which will make the car ultra smooth. This is a simplification but always increase your bump to get your tire temps where they are in operating range, and run as little rebound as possible where the car feels stable. high rebound will caus the car to not dive or squat as fast if you low damping.

This is my race setup. I prefer tweaking setups for races rather than TT, as I tend to race more than anything else. I just tried the one setup but will be tweaking parameters over the next few days (literally). I do minor changes then try and run a 10 to 15 lap race that I am always accustomed to for comparison. This setup was much different that the one I had prior where I used Jussi's program and took sometime for me to adjust, but in the end I liked it much more!!!

Pcars telemetry does have udp support that is how I have been using it from my gaming PC to my laptop - so in theory it should work with PS4 but you will have to run the app on a PC . There is a connection manager option in the app which allows you to use UDP

So the window is fixed size, I'm not the best programmer and didn't think about support for multi resolution until after I made it. what resolution do you use? I can shrink everything so it'll be view able for you in the meantime.

and yep my wheel calibration was wrong, so neutral steer was only going to work for me. I will have an update in the next couple of days correcting this.

repsol23
05-04-2018, 17:51
No worries, I have 3 different resolutions I run depending on where I am using my laptop. At work is small resolution due to desk space and home is 2k res. No need to re-write at the moment as I am just messing around with files and importing for the moment. But just cause you asked my work resolution is 1366 x 768.

Honestly, I would really prefer an option to print the images if possible. I use a 3 ring binder that has all my "racing" info, setups, timings, and (most importantly) all the names of the unskilled racers who ram me or take me off track intentionally. Lol. Had a really crazy idiot last week who had nothing better to do than follow me and take me out on every corner he could, was absolutely frustrating. Anyhow, back on topic!!!

Ah right, thats helpful. I liked the sound of this app so looked at the online manual for the telemetry app and it only mentioned shared memory not udp.

Your info now makes it possible to give this a go now so thanks for letting me know.

That would be fantastic making it an all in one app and not dependent on any external software. Using UDP will also have the benefits of making your app usable across all the platforms too.

You're app looks just what I'm looking for, I want to make improvements but I'm a real novice at the numbers and the understanding of them. I've seen your videos and to relate the changes based on a understanding of a visual graph certainly seems to make things look easier. I shall certainly try.

As well as races, I run a lot of time trials against a group of friends. Do you have a different process for using your app for a TT set up as tires start hot, if so would you consider doing a similar 'Tune that car video' for a TT showing how you use the app to tweak the set up or document your steps here?

Thanks

Zeratall
06-04-2018, 08:52
Dozuk,

Sorry my videos that'd typically how I would do a setup for a time trial, because you don't necessarily have to worry as much about tire temperature optimization, etc.

For race tunes I use the tool in a similar way, but importantly my ratios are dependent on how confident I am in the car (rebound) and how hot or cold the tires are (bump).

Sorry, I'll show all screen. I've just selected the car (FC) from the drop down and not changed or added anything. All values are the default ones pulled through on selection of the car. Just found it odd that no red line was present.

That is correct dozuk, the graphs at the bottom stop showing if the car is over critical damped, so for this instance the front (red line) disappeared. This isn't necessarily a bad thing just a limitation of the program, most cars your never going to want to be over 100% but race to built cars like formula C lmp etc, you will have higher values of bump because you can use bump to get the tires to their ideal temperature.

Reason it stops showing past 100% is because the equation for the response graph after 100% has imaginary roots and takes a different form.

Hi, very new to this. I would be grateful if anyone could comment on the set up below with any advice of what I'm doing wrong or right? I've not tested it yet, I just wanted to see if my assumptions are right or if I'm completely on the wrong track. It's a formula C for a time trial so I've lowered the bump figures as the tyres will be good temps, I've tried to get the lines to converge whilst keeping in Q2 for a formula car.

From my limited experience I'd say you are on the right track, looks good. From my understanding your setup would me towards the "softer" end as you are nearer to the lower red line.

So for the tire analysis it won't tell you bar or psi, you should be entering temperature, also, it's a unit less calculation so it doesn't matter if you enter c or f, don't pay attention to the numbers it gives you they purely mean scale and are not telling you an exact setting to punch in, if the number is positive you have to much, if it'd negative you have to little.

Sorry I've been crazy busy but that looks like a really good starting point for a built to race car it might be slightly low damping % I'd suspect your probally going to want to increase the dampers slightly, if you need more help please let me know and I can help you dial it in, often with the tool it won't give you exactly what you need sometimes you'll need to increase your %. For instance if you noticed the car tire Temps were at optimal, however you were very unstable (rate of weight transfer) you could increase your rebound % to make it more reliable.

So I think I may know the problem, its due to the calibration process. I think I may have screwed up my calibration process in game. So the cal process has 2 steps, step 1)turn full lock, then step 2) says "Turn the wheel 90 degrees".

My interpretation is to turn full lock and then 90 degrees opposite direction of full lock, however some of the guys have mentioned that its 90 degrees from neutral, I'm going to attempt to recal and if it results in different results then I'll fix the program, as it would only work for my inputs lol.

So the whole purpose of needing to know steering lock is because to calculate the neutral steer channel, I need to measure the steering angle of the tires themselves. I'm doing this by measuring the ingame wheel, then using the steering ratio to determine the amount of rotation of steering wheel to tire.

Zeratall did you manage to have a look at the calc and whether it needs amending

Thanks

Abewoz, I can, so the data I'm using doesn't have thst information, so let me do some snooping around to see if I can find some dataset with all the gear ratios for each car. If I can't I can do it manually by loading each car and writing them down however this would take much longer to develop than the first option. Let me do some research and then I can get started on this.

Ah, I was seeing the same thing and couldn't figure out what it was telling me.

Unfortunately, this part is a little difficult to keep entering the values in on xbox. I can't really freeze the screen to get a look at the numbers so I'm losing temp when trying to go back and forth with the numbers. Taking a picture of the screen with my phone was the best option. I've just been going back to doing it roughly in my head since the extra step to type it in was adding more complexity. Not your fault obviously and it's probably easier to use on PC if you can freeze the screen to see the temps.

I'm hoping they'll have the outer/middle/inner temps working in the UDP stream (or maybe it is in patch 5?) so I can record them in telemetry and look back at the end of a lap.

So my way is extremely tedious but I also use pc telemetry to export a csv file. I export all 4 tire temps, import to excel and calculate the average temp for the lap. There tends to be 2000+ data points but at least it gives a overall temp that you can look at adjusting. Hope this helps.

New update, also went ahead and added my plans for upcoming updates to give you guys a heads up on what I'm working on.

Version 1.15.0

Updates Include

Fixed the bug with the nuetral steering channel. Graphs should be correct for given steering lock.
Fixed the tab order on the differential page. The tab order should flow from top down.
Made the car weight an "Editable" field. Still waiting on an updated data source for the patch 5 updates. Expect an update when they are made availabe.


In the Works

Resizeable windows/contents exepected release (4/27/2018).

Did they fix the outer/middle/inner tire temps in patch 5? I remember them saying it was going to be fixed, but I haven't checked to see if it is working. It still had the same main temperature across all 3 of them last I checked. I really hope it's working now.

There are a number of other tyres related temps in there (carcass, wheel, etc.), but the 3 that you see in the game telemetry were all set to the same value as the "overall" temperature.

Using version 1.15.0 I was looking at the damper settings for the Renault Clio and I think there is something wrong with the graph scales.

When the app is opened you only see the blue line in the low speed graph - assumed that the red line is perfectly equal to the blue and as such is behind the blue . If I lower the rear slow bump the shape of the blue line changes however the red line still does not show - I assume that is what it should do. If I alter the front slow bump down from 15250 to 14000 the red line now appears - if I increase the front slow bump the red line disappears again. If I increase the rear slow bump above 8500 the blue line also disappears.


I have tried with other cars and the same happens so it appears above a certain level the graph lines disappear

Hey guys version 16 is out, the GUI is now resizeable, minimum resolution is 1600x900, but now the GUI can be made larger so the graphs can be larger and easier to see.

The new sizing isn't great if you're not using 16:9 it seems. I run it on my Surface Pro 4 which is 2736x1824 and it's barely fitting, even at full screen. All the buttons on the right side are partially cut off, no matter what size it is. Not sure if there's anything you can do here. It's usable, but it's certainly not comfortable. If you could put a split between the graphs and the rest to allow sizing them smaller or something that might help. On this display, the graphs have looked fine on the previous versions, but I'm guessing people must have been having issues with them on other resolutions.

I also wanted to make a UI request for the buttons for the dampers, springs, etc. Can you disable the button if no adjustments can be made? For cars where some values aren't adjustable, or when a value is already at its max or min, I click on it and then have to click again on the popup that tells me it can't be adjusted any further. If you could just not let it be clicked and disable the button then we could visually see that it can't be changed (0 clicks instead of 2 clicks).

FYI, there is also an exception thrown when you try to click any of the buttons before a car is loaded, so it would prevent that from happening too.

Zeratall
01-05-2018, 02:26
Turn off windows scaling,, set it to 100% everything should fit after that, the default window size is 850x700 which is 1/3 as your resolution.

I'll address the buttons, its doable but will require a little of coding because the way I have the data setup

g.stew
01-05-2018, 19:46
Scaling is 200% by default since it's a High DPI display. 100% is not usable since it's so tiny. I've been trying 175% which fits much better but can be blurry in some cases. I'll stay with that for a couple of days and see if it bothers me.

Thanks for looking at the buttons. Maybe I'm the only one it bothers, but I think that will save a lot of time. Even the game itself doesn't do it well since it doesn't show you when you've hit the min/max, so this would be a big improvement.

No problem. Based on the exception stack trace I saw (when clicking on a +/- with no car loaded), it looks like you are creating your own text fields and button controls and using the click events to change the value. You might look at one of the UpDown controls (DomainUpDown, NumberUpDown I think) to handle all of that logic for you. Then I think you can just bind your list of values to the control and it will handle increment/decrement events, etc.

Anyway, I'll leave you to it since I wouldn't like much if someone was telling me how to do things. Figuring it out is the fun part anyway ;)

YES, UDP Should make it into the tool in same fashion or other this weekend, I have gotten the code to read the data now I just need to do things with it, be on the look out for an update this weekend.

No you cannot import export the setups from the game into the tool, however I'm working on a database now where you can upload you tune to the Pc2tuner cloud and download other people's tune, which will make sharing tunes very easy and convient,as it'll place the files into the game folder for you.

Last everyone who has bought the tool should receive emails when the tool is update if not, please contact me via discord with your name and I'll verify your purchase, and give you the link.

Additionally with the new update, I have enabled auto updates so when the program updates after version 40, the program will update itself.

Version 42 is now live, if you have version 41 when you open the tool it will prompt you to update to version 42. If not pleasure double check your firewall and verify you have allowed an exception for PC2Tuner.


This release incorporated UDP into the tool, as well as a new tool called "Engine Power". This tool will let you run a in game dyno run and measure the resulting horse power and torque. An example is down below. To run the tool. Enter the gear where your gearing is close to 1:1 (cannot be the last gear of the car). Then travel down a straight, and give it full throttle, the code will start the graph when you first shift into that gear, and continue to graph until you shift up.

Hahah no worries you look at the gearing and just choose the gear close to 1.0 (can't be the last gear) that being said I'm not entirely sure it's even needed since the car measures power directly and we're not setup on a dyno measuring power via wheel rotation.

30-05-2018, 21:41
Correct you would choose 5th,the way the code works to get clean graphs is it starts graphing when you shift into the gear, and the it'll stop when you shift in the next gear, that's why you cant use the last gear. That being said whst I do go grt nice curves is shit into the gear (lol car can't stall in pcars) and then just give it gas as soon as I shift it into gear, you'll be at like 1600 rpm and it takes it a while to build up, since we're starting to slow, and the I just keep on the gas until i hit recdline then I shift. And it gives the new power torque curve

Bought the app yesterday based on the feedback, grabbed all the tuning videos and watched a couple a few things..

I use PC Dash as well but it appears that it only likes one app accessing data from PC2. I did a workaround by running PC Dash on my lappy, would prefer not to, though.

Configuring dampers, I can see the logic behind it but the results at the bottom of the page - how do I know what I should be aiming for in each % - ok, match left and right to balance them but how do I settle on the value in the first place?

UDP for tyres appeared to be working which I believe it a new feature - it's asking for a value for optimal temp. Pressure/temp is a little confusing to me. Info I can find appears to suggest an optimum pressure when the tyres are warm (which I don't recall ever seeing sims modelled like this before), not necessarily just an optimum temp. Also the temps would change depending on when you measured them.. when is the best time to stop the sim to take a temp snapshot? Should I ignore pressures and focus just on optimum temps?

The following is a typical process flow for tuning your suspension dampers.
SPR
You can set your spring stiffness for approximately 3.1 front, and then adjust the back for a 4 to 7 % rear spring stiffness.
To start off, you want the least amount of ARB possible to retain all the available suspension travel.
So set the ARB’s to the lowest values while doing the damper testing and adjusting.
BMP
Next, you can set all your dampers to the lowest “critical dampening values” where front and rear are essentially equal in the calculator.
i.e.: If the rear lowest is 20 and the front lowest is 15, then set both to 20.
After setting to the lowest settings as above, do a few Laps and feel how the car handles. What you are looking for is if the car is walking, having wheel hop in turns, or it feels like the front is skipping around.
Now, in the calculator, double the “critical rate” bump values, and test again. You can keep doing this process until the car feels planted and the walking around or wheel hop has been is reduced or eliminated.
RBD
Now you can adjust the rebound. When you have the bump low, you could possibly experience spin.
When you adjust the rebound that is what you are looking to eliminate.
Therefore, keep adjusting the rebound until the body roll in turns is smooth and not abrupt.
Once you feel the body roll is in control, then adjust the front or back slightly until the OS or US is where you like it.
ARB
When you are satisfied with the transit response, you can move on to the ARB’s.
After adjusting rebound, the car body should lean smoothly in entering and exiting the turns as you would expect. However, the “amount” of body roll, or “where” the body sets in a turn may be too far.
This is where the ARB has come into play. You can keep adjusting the ARB until that total travel of body lean is under control.
Therefore, you adjust body roll rate with the rebound, and its maximum distance with the ARB.
As your car starts into the start of the turn, (a transit) you will have damper and then ARB effects.
The damper exhibits force that comes from the velocity of the damper.
Then when the cornering reaches a steady state, (aka, the car is set, max cornering roll) the ARB comes into play because the rate of body roll in the car is zero.
As a result, you adjust transient with the rebound and the steady state with ARB.

I'm certainly no expert on tires, but I usually set the cold pressures to obtain the "desired" hot pressures after a minimum of 5 laps to get them warmed. Then if they are within a reasonable temp range, I just go with that.

Or you can do TT, and they start off warmed, and then they settle after about a lap or so. Hard to say definitively since there are so many variables involved.

Hey bud regarding your tire question, the tire setup tool is looking for a temperature gradient, it'll tell you if you have an ideal gradient, for camera and pressure adjustment, the tool also calculates how much over the "ideal temp" it's just a number you enter to determine if your overheating the tires. If you place the ideal temp somewhere in the middle of the optimal operating temperature range you'll be good to go. If you don't know what number that is, I typically use the values given when starting out on TT.

Hi Zeratall,

I will buy your tool, thats for sure but I want to ask if it's already possible to connect a running instance of PC2Tuner on a second Pc and then connect it to a PC running ProjectCars2? So we don't need to jump in and out of the game.

Thanks in advance and keep on going!

Version 1.0.49 is now out updates include:

1) Took away the suspension pop up message, now the buttons disable and recolor when at their limits.
2) Added tire wear, brake temp peak, and brake temperature average to tire analysis.
3) Fixed the tab order on the login screen for the tune database.
4) Made the password blank on the tune database login not show. If you create an account, you will get a pop up box to confirm the password.
5) Fixed the issue where the tune database would sometimes lose your connection causing an error when uploading.
6) Added everything on the setup to "Notes" so users can enter the entire setup, and put them on tabs.
7) Added the damper knee speeds for front and rear so you no longer have to look at the damper graph to determine at what speed the dampers transition from low to high.
8) Added help write ups for each analysis, explaining how to perform the analysis, and how to interpret the results.
9) Added the Carlist for the new "Spirit of Le Mann" DLC (Amazing DLC BTW)

Version 1.0.51 is now out, update includes:
1) Changed the way the tire setup works, instead of taking instantenous data points, it takes a rolling average of 10,000 samples. This helps give a better "overall" picture and will help getting consistent temperature readings indepdent of where on the track you take them.
2) Added Engine Temp Peak and Average

Hi, you're looking in the wrong place mate. The udp settings are in the game settings within project cars 2 and not a part of the PS4 settings. From memory, I can't remember exactly where they are but I can look tonight if you have no luck finding them. It's quite straight forward, you enable the project cars 2 upd and frequency of 1, then start a lap and get the app going on a laptop connected to the same router (wifi). It should just pick up the data once you hit connect to udp

Oke perhaps I sound very stupid but I started the app yesterday. Watched your vid on the Ferrari 488 GTE.
You load in the default settings of this car and start immediately alter settings. But how do I know what to change?
You say, the bump and the rebound are high and a bit of a strange setup. Cool that you know this but for me as a nOOb I really can’t tell from this default setup what is a good or “normal” bump and rebound for example.
Everybody is telling this tool is great and helped them to setup a car with ease and although I really believe that and appriciate the tool and the effort you put in it, I can’t understand it at all.

Maybe it is just a matter of turning some knobs and see what it does with the car but as said you start immediately turning the knobs in your vid. I suppose this is your experience with tuning cars and therefore you know what to alter on forehand.

I do not see how this tool can make me a good tuner without any knowledge of car tuning. ;)

So I told I would start the tool with the Ligier JS P3 but when I load in the default tuning I see a whole lot of info but totally blind about what to set or leave as it is etc..
a bit hard to explain for me as English is not my native language and therefore it is a bit harder to express myself. I hope you understamd what I try to say here.

There is a learning curve as it's not a program to give you tunes, but a tool that helps you see the data in a way that makes it easy to make adjustments.

That being said If you read the "help" it'll explain the theory and suggested values for different types of cars I know the bump and rebound were high because they were at the top of the range.

Also if your looking to understand the basic concepts of the car, as in whst the dampers do and whst critical damping % is I recommend you watch my PC2Tuner "how to" series the video is when pc2tuner was young and you might not recognize the interface but all the concepts are the same.

You load in the default settings of this car and start immediately alter settings. But how do I know what to change?


this is the dried-up-to-the-bone flowchart you need to follow:

1) springs (set them so spring bias is close to 0, using ride frequency values as Zeratall reported above)
2) dampers (set them so front to back have similar % of critical dampening, using values as Zeratall reported above - hish speed dampers should have a % between 30 and 40 in most of the cases)
3) damper histogram analisys (check if each histogram is kinda symmetric, also check that front to back you don't have big difference in average values - .1 is a good tolerance. Make corrections to dampers accordingly)
4) ride height analisys (blue line must be matching the red line - or be very slightly above it - in the straights)
5) tyre setup analisys (too long to explain check the videos)

There is a learning curve as it's not a program to give you tunes, but a tool that helps you see the data in a way that makes it easy to make adjustments.

That being said If you read the "help" it'll explain the theory and suggested values for different types of cars I know the bump and rebound were high because they were at the top of the range.

Well the wait is over my good friends, thanks to our newest developer Longtomjr the UDP revamp Update is out, it now shows all of our special analysis in a typical telemtry screen where you can collect laps as you race and then compare all the data after the fact. All the data gets logged, so you no longer need to do laps for each analysis separately you can tune the entire car in about 5 laps now!!!!!!!

The changes you make on the videos are quite extensive compared to the default settings. Does this mean that the default settings are way off and all wrong?

If so I wonder why the default settings are so off?

I too wouldn't say the default setups are wrong, but when it comes to driving styles they could be way off for what you are liking. This is why the tuner app is so amazing, it makes the setup process much easier. It still involves some understanding of what changes need to be made but it sure beats the old school way of click this and see what happens. Lol.

The analysis portion is asking for Tyre Diameter.. can't these be properly pre programmed into the analyzer, taking all the relevant data from the car selected? Or is this information not available for all cars? I'm currently testing PC2tuner on the Caterham SP300.

It also asks for the wheelbase and steering ratio. Same thing, can't these boxes just be populated right from the selected car in PC2Tuner itself?

This might help others with small resolution settings on small laptops
i solved my dpi scaling and font problems .....now Data boxes are working fine and webpages are back to normal size


first reduce your font scaling to 100% Smallest Font so PC2TUNER works correctly on small resolution settings

then i used a firefox add-on called (No Squint Plus) works on chrome as well....its got global font setting section
that fixed all webpages back to normal 125% font again.........with out the hassle of using zoom-in every time u open one online

How important is wheel diameter because I don't see that being easy to find for a lot of cars?

We are making a list. If similar to the wheelbase most of the tire sizes are fairly easy to find because the class they are in mandates a specific tire size.

Everyone Version 2.0.1 is live, decided to go with a sneaky patch this time (but don't let it fool you, this is a big update). Updates include the following.

1) Fixed (we hope) the bug fix with random crashes.
2) Added Fast Fourier Transforms (FFT) for Suspension Data. Don't let it scare you (manuals to come). The tool lets you view the suspension data in the frequency domain to determine if your getting HS or LS distrubances, and if you need more or less overall damping.
3) Improved the Histogram accuracy, added a new metric (skewness,kurotosis).
Skewness:
If the number is positive, it means you need either more bump damping, or less rebound damping.
If the number is negative, it menas you need either more rebound damping, or less bump damping.

Kurtosis:
If the number is low it means the histogram is tall and skinny (stiffer suspension).
If the number is high it meanst he histogram is short and fat (softer suspension).
4) Added Traction Control and ABS to the Wheelspin Graph. These are optional but will draw a reference line on your wheelslip graph to help you see if your activating these driver aids.
5) Added Lateral Wheel Slip Angle, this graph indicates if you are achieving the ideal slip angle for the tire. Still waiting on SMS confirmation on ideal lateral slip angle for different tire compounds, but it's safe to assume its around 6-12 degrees.
6) Added Downforce Graph, this graph indicates how much normal force is acting on each wheel, on straights this is purely the downforce generated. in cornering it shows the downforce + weight transfer.

I highly suggest including at least the ones you already know/have information about. This is something one kind of expects as a paying customer. Basically you do not get the full functionality of the software without knowing these.

Would it be possible to get the in-game wheel diameter from a decoded pC2 install (which is needed for modding as far as I know)? If I remember correctly each car has some basic physics text file that lists all kinds of things. Or maybe it would be possible to ask Casey or Jussi to post the missing data?

cpcdem
11-08-2018, 19:38
For the wheel diameter I think it should be easy to deduce it from the telemetry data, just read wheel rpm and vehicle speed while on track and this should give the diameter. For the rest I see no easy solution...

Even without the missing data the program is worth it. The data that is not auto-populated does not require much research as there is a spreadsheet which lists them. Steering ratio is driver dependent.

This application is not a silver bullet, but it is pretty close and the amount of time tuning a car for the driver is substantially reduced.

Zeratall
12-08-2018, 00:57
Exactly what Y22 said, this is suppose to be a tool, in which RST provides training and help with via the RST discord. There are some inputs that are always going to be unknown and require users to input them, that's the nature of the game, and even pro software requires the same. Additionally, the price of the tool is priced such that it is suppose to be a tool. It's not a program that just tunes the car for you. Once you understand the graphs which we pride ourselves on helping with, it's hard to imagin tuning a car without it.

Also the list is already publicly available as we go through and correct the ones that are incorrect.

ShneebnaMRR108
12-08-2018, 13:47
I actually prefer to input the required variables myself. The RST tool has reduced the TtT (Time to Tune) and breathed new life into the game. Even if you are already a good tuner, who wouldn't want to at least check yourself against a benchmark. Who knows, you might actually find something you never expected.

Great work on the part of the RST development team.

Voodoochild
13-08-2018, 09:17
a little trick to figure ut the correct diameters to input: start with some sensible figure (gt3 cars IRL usually have 680-705 diameters) and plot your chart, then adjust the diameters so all the 4 lines will start from 0. When you hit "enter" the chart will auto update.

bmanic
13-08-2018, 19:16
If there already is a spreadsheet with the data then why on earth is it beneficial for the user to have to manually insert that known data? I just don't understand this kind of logic. Steering ratio I can understand, but even here it should definitely use the DEFAULT car setup steering ratio to start with. I suspect very few people change this (sometimes I do, most of the time I don't).

My point is this: The company that sells the program has this data. Why not have all the known data be entered from the get-go? The very reason I purchase these kinds of software is to make things quicker and easier. Most of this can be done manually and calculated yourself with an excell spreadsheet. Heck Jussis excel sheet is a great start already.

.. but I'm willing to spend money on things that make everything quicker and easier. When I do spend money I expect stuff to improve.. so thist was my suggestion. Automatically enter all the known data. If it is unknown, then yeah sure.. let the user insert it and as soon as it's verified to be correct data, then add that to the next update.

Zeratall
13-08-2018, 20:32
Again, we are going through the list and checking them all, we provided the list to get users a starting point, the intent is to integrate our list with the program when we're done.

We are working dilligently and as quickly as possible, but we want to provide accurate data to our users. This data has to be manually farmed because it's not publicly available from SMS. If it was, this feature would have been avaliable at release.

ShneebnaMRR108
13-08-2018, 22:56
I would "suspect" that quite a few users change the Steering Ratios. Especially since it's known to also effect the FFB, as stated on this forum elsewhere. If in fact the Steering ratio was already input automatically, and you wanted to change it, then it would be a Tab over, Delete, and Enter, instead of just a Tab over, and Enter. Trivial stuff really.

Voodoochild
14-08-2018, 00:18
When I do spend money I expect stuff to improve.. so thist was my suggestion.

pc2tuner went from being a pretty simple suspension calculator to be a pretty awesome and complete telemetry tool in like 3 months, while the price went from 10$ to... 10$.

so yes, stuff is improving.

I love this tool and think it's incredible value for money at just $10 despite all the improvements that have been made to it over the last month or so. I do have to admit to struggling to understand fully how to use it at the moment though and am really waiting on the release of the manuals to give me a better understanding of all things involved in this great tool. I do access Discord to check up on things as well and have enjoyed reading through everything on there and have copied and pasted bits and pieces to try to give me a crib sheet of what I need to do but if honest I do find that particular medium quite difficult at times with it's very linear structure so finding anything in particular isn't the simplest. But that's just me as I am so used to the generic forum structure of things lol

As for the entering of the the missing data that is no problem as far as I am concerned providing I know what to enter which is where I was struggling somewhat with the wheel diameter for instance. But having had some advice from ShneebnaMRR108 and seeing the post of Voodoochild above (post 235) I am now up to speed on how to get that correct. Maybe that's something that could be added to tool to highlight to other users like me that are unaware that the data from the car info spreadsheet might not necessarily be correct.

Fantastic work though by everyone involved in this gem and something that I know will get a lot of use from me over the months (and years) that I am playing this great game. I would be happy to pay extra for the improvements that have been made as the work involved is very much appreciated :applouse:
