Gents:

I am curious as to which temps effect timing?

Is it just IAT temps or coolant temps?

Thanks!

From what I can remember:

Stabilitrak
Torque Management (Engine and Transmission)
IAT
ECT
Speed limiter

These will all pull timing unless you play with the parameters to tell them to do otherwise... One thing I like using is adding or subtracting degrees from the IAT table, no way you'd get pinging and knocking in hot weather again... and inthe cold, I've added at least 3*s of timing!
