Timing curve vs. engine temp vs. IAT temps?

[TJD]

Gents:

I am curious as to which temps effect timing?

Is it just IAT temps or coolant temps?

Thanks!

There are separate tables for both IAT and ECT which can pull timing.

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!

Knock also pulls timing.

Thanks...
