Pretty sure the computer takes care of it all with launch control. Otherwise, with no launch control: throttle modulation!
Apparently the base C8 diff. is 4.89 so the trans. must be geared differently than most cars with 2.85-3.73:1 rear ends.
I just looked it up and the trans. is geared as if you started in 2nd in most other modern automatic vehicles. 1st is 2.91, 2nd is 1.76, 3rd is 1.22 and 4th is .878.
The ZL1 A10 doesn't hit 1.00 until 7th gear, for comparison:
1st 4.71
2nd 2.99
3rd 2.15
4th1.77
5th 1.52
Take 2nd gear, for example in the ZL1: 2.85 rear combined with 2.99 2nd = 8.52 overall. 2nd in the Z51 C8 = 1.76x5.17 = 9.1, so it's only a little lower than a ZL1's 2nd gear. Base Stingray = 1.76x4.89 = 8.61, pretty close to a ZL1 A10's 2nd gear.
Numerically, it makes sense to have such a low geared diff. with those transmissions ratios. Interesting choice on GM's part.
