    Does't PC2 always auto-blip/rev match?

    I also drive with paddles and use clutch only for starts. In AC, if I don't enable auto-blip, cars will sometimes spin under me on downshifts, I think because sudden engine braking applied to rear wheels breaks traction and the wheels just slide. Even if they don't spin, there is a clear jerk and a tire squeal. I have never experienced any of that in PC2, so I assumed the game auto blips.

    In pcars 2, you sometimes can change the value of engine braking in the car setup.
    But no auto blip.

    There's no auto blip AFAIK, that's sort of covered by the 'perfect synchromesh' that the gearbox model uses. Wheels locking on downshifts can still happen in pC2, if you downshift so fast that the engine hits the rev limiter.

    There is auto blip, even with automatic clutch disabled. But only on cars that have it irl (like GT3 cars for example).

    Wheels definately lock on downshifts- ive managed it in spectacular fashion in my formula rookie using my H shifter- 4th to 1st leads to a broken engine and red faces in the gravel..

    Yeah the Frookie is a good car to do this

    I generally meant that there would be no lock up (or far less than in AC) when NOT hitting the limiter.

    Having said that, just yesterday I did 2 online Formula Rookie races (it's a glorious car), I was sideways a lot, out of track several times, but always due to poor racing technique as in braking too late, or just wanting to have fun. For sure I hit the limiter more than a few times. I was never caught by this type of downshift-related lockup, which has hit me often in AC (in cars from Toyota 86 to Tatuus).

    Could it be that PC2 autoblips when paddles are used but doesn't with H-shifter?

    As Bealdor said, it autoblips cars that do actually autoblip in real life, like GT3 cars, but it does not autoblip cars like vintage GTs, which did not have this functionality. You can easily see when autoblip happens, just watch the speedometer while downshifting in GT3s, you will see the throttle input (green line) briefly spiking at that moment.

    But what is really strange in PCARS2, is that when you have autoclutch enabled, then not only it blips downshifts in GT3 cars which is correct of course, but it also engages some fantasy clutch pedal as well, making downshifts even more fluent. And what's even stranger, apparently it uses such a clutch input even on upshifts! This is why it is slower having autoclutch enabled, even when you race in GT3 cars. I really hope such bizarre things will go away in PCARS3.

    Yeah, I rarely watch the gauge that closely in race, and I think PC2 does not show it in replays (unlike AC, which [optionally] does, like here I have nice throttle blips e.g. when braking for Druids, which I did not do myself, it was the game's auto-blip)

    That's probably the explanation. I do have autoclutch enabled in PC2 (not in AC, because it prevents using clutch for launches there). Maybe I'll try some driving without it, though on the other hand it will be weird with a sequential paddle shifter, which for now is my only way to change gears in sims. Also I typically keep my left foot on the brake and use it for braking, as I do in karting and also in road cars with automatic gearbox, with or without sequential shifters. Only if I get a manual rental I switch to right-foot braking. Maybe I'll do more of that in PC2 when (if?) I buy an H-shifter.

    I thought GT3 cars had clutch pedals.
