I have disagree with you on this one, aajami. Although you must turn off DSC to activate LC, once you do activate LC, I believe it retakes control of the traction control system and runs its own special program to help you get a good launch.

Of course my opinions have no basis in fact, as usual.

I don't have facts either - but I agree with what you are saying.
I don't have time to look it up, but, I believe that there is some details about how LC works in either the original M-DCT press material or the M3 aftersales material provided to technicians. My recollection is that there is a lot going on with the ECU in order to provide maximum acceleration. Of course, as we know, it doesn't always necessarily work out as you might hope.
