TC limits engine TQ in a straight line during a burn-out. If I leave it on during a burn-out it limits engine RPM to about 3000 until the tires grab and the TC light is illuminated. If I turn it off - it allows the engine to hit the rev limiter if the burn-out is sufficiently aggressive. You tested this yourself recently in your own RT.I don't think TC will make any difference, either way. Afaik, TC does nothing to clamp down on wheel spin unless you are in a turn.
TC is not a rev limiter in the conventional sense - it uses torque management to limit wheel spin under a variety of conditions. The RPM at which this occurs is condition-dependent.It doesn't limit torque, at all, as far as power getting to the ground. It just puts on an earlier rev limit if it detects the wheels spinning freely. Either way, the wheels are spinning freely, and the power isn't going toward moving the car forward like it should. Sure TC will be the difference between a midrange burnout and a redline burnout, but who cares?...the tires are just going up in a spin, either way, instead of hooking.
That was my point...don't expect that TC is going to make you hook better or not. It doesn't work at that threshold. Either you have the traction to put the power down or you don't. As long as the tires hook, then TC will not have mattered, either way. We really are saying the same thing...TC doesn't really have an impact on a straightline race, except I'm just using the term generically to be inclusive of TC/ESP all together as a program. It's when you are turning and overpowering the rear, when they come into play.
Personally, I don't think all of that is going on with TC. All it does (when in a straight line) is detect that wheel spin is in progress, and then applies a premature rev limiter. It does not stop the wheel spin, nor does it evaluate the amount of torque for particular condition. It allows prodigious amounts of wheel spin, as long as rpm stays below the set limit. Personally, I think that is just a measure to protect the powertrain, rather than a behavior to enhance traction. If you find yourself putting that much wheel spin into a race, you won't be winning that race, because that is essentially a whiffed launch. The only thing TC did at that point is limit the whiffed launch to some mid-range rpm instead of allowing a whiffed launch at redline. If this a race from a roll, it's much less likely there will be wheel spin from natural causes, so TC will not have even activated, anyway. If it is a race from a roll, and you do create a wheel spin, then TC will just behave as described above...won't stop the wheel spin, but just limit the rpm at which it occurs.TC is not a rev limiter in the conventional sense - it uses torque management to limit wheel spin under a variety of conditions. The RPM at which this occurs is condition-dependent...It looks at the amount of TQ required to spin the wheels - it takes far more TQ to spin the wheels on a dry road vs. a wet road - and the system definitely knows the difference and adjusts TQ output accordingly (and very rapidly)...
