This car just pisses me off every time I launch because I never know. Now I just turn it all off and trying to learn it that way. I seriously think the problem is equal between the M6 and A10. And I don't really think it was extra time spent on the A10 to get it right. It's just the nature of auto v manual. But then what the heck to I know.
The consistency problems you describe align perfectly with the problems I describe with using a "% of Wheel Slip" for launch control. The simple fact is, a percentage doesn't work well at low speeds. The percentages can just spike arbitrarily due to very small amount of sensor error, latency, etc. even a small amount of actual slip can result in massive spikes in the percentage value before the front wheels get moving.

GM could ignore the readings at low speed to avoid the problem, but since it's launch control and not roll-race control, I believe it's a flawed approach... But what do I know?
