Looking for info on how much of an effect does the values in the IAP map have on the afr and in what areas? My understanding is that the numbers across the top are the diff between the barometric pressure and the amount of vacuum in the intake tract (what map sensor sees). And that this map only affects throttle positions less than 10 -15 percent. Also that the high numbers to the right = closing the throttle, middle range numbers would be cruising or steady state , numbers to left (smaller) would be when opening the throttle creating less vacuum. Correct me if I’m wrong. What I want to know is the effect that these values have on cruising afr. Thanks.
