what effect does the IAT have on the engine performance
what effect does the IAT have on the engine performance what effect does the IAT have on the engine?
when the IAT temp goes up what does this tell the computer and viseversa
how does it use the IAT?

thanks for the info.
ok now one more question.
is it possible with edit to adjust the amount of timing pulled when the temp rises or the amount added when the temp drops?

ok with those programs is it possible to increase timing when temp rises and decrease timing when temp drops
pretty much make it do the total opposite of what it does.

There is a chart in Edit: IAT vs load timing. It pulls timing depending on temperature and MAP.
To my opinion very useful for superchargers application when the charge cooler doesn't work fine.
I wouldn't remove this safety, in fact I see a lot of KR when the air is too hot and I set a too low timing reduction.
In my opinion it's better to optimize the intake (functional Ram Air or so).

Detonation
Detonation is the spontaneous combustion of the end-gas (remaining fuel/air mixture) in the chamber. It always occurs after normal combustion is initiated by the spark plug. The initial combustion at the spark plug is followed by a normal combustion burn. For some reason, likely heat and pressure, the end gas in the chamber spontaneously combusts. The key point here is that detonation occurs after you have initiated the normal combustion with the spark plug.
Pre-ignition
Pre-ignition is defined as the ignition of the mixture prior to the spark plug firing. Anytime something causes the mixture in the chamber to ignite prior to the spark plug event it is classified as pre-ignition. The two are completely different and abnormal phenomenon.
