Out of 5 passes I tried one with T/C off and it was wheel spin for the better part of 60'. No go for me, need more practice I guess.
T/C on worked well, at launch I just try not to let the wheel spin so the engine speed management doesn't kick in that results in a little hesitation.
I find it easier launching doing my 0-60 mph runs on dry, clean blacktop/asphalt but that may be from not being so pumped like at the track.
I launch from idle with my auto.
