Yes I know that Rogue. The idea is to prevent knock or temp induced timing retard....effectively advancing it by as much as it would have been retarded at higher boost, higher temps, etc
What else does the IAT control besides A/F and timing
I don't see that the engine knows what the temp of the charge is after the supercharger. It must interpolate it using other variables like IAT, MAP, MAF, O2, rpm, etc.......but if the IAT was fooled....
So if you were intercooling, how would it know how much cooling after the IAT sensor?
If you were cooling effectively but the IAT is detecting 100F readings, won't it retard the engine.
Hey, I admit I don't know squat about the programming of our PCM'* but I'm really curious to understand.
