[s-cars] MTM Stage 1+ AND Pinging AND Hot Weather....

[Robert Pastore]

Cody:

The MTM 1+ runs the car very lean at part throttle and it the transition to
full throttle.  Light detonation is common in the conditions you describe.
The IA III+ (Lehman chip) timing chip runs richer at transition and I've
never seem this problem with it. That being said, the power surge with the
MTM is more abrupt (IMO more fun) but I can't really say that it is any
faster.

Anyone else have this issue? Seems to be most common when my car has been
sitting idle at a stop-light and/or parked for a short time letting the
Intercooler get Heat-Soaked. If I step on the gas in say 2nd-3rd gear and
get up to around 22-24PSI...ping ping ping....yikes detonation.

Thoughts besides larger intercooler or letting car cool down (Air Intake
Temps) before getting on the gas? Switch Chips?  RS2 EM make a difference
with this issue?

Thx
