I still don't get it. With power braking the TC limits the revs anyway, even at full throttle.
If this is what happens with Launch Control:
You're on the start line, the gearbox is in Drive, you press the brake hard and when the time to launch comes you floor the throttle. When the revs reach the maximum the TC will allow you release the brake and the car starts moving forwards, rapidly.
How would LC improve on that?
How are two stage rev limiters related to RLTC Launch Control? Totally different thing isn't it? I thought 2 stage limiters for primarily for manual transmissions too.
