could rail pressure be reason for rich at idle?
ok so seems like everyone i know their car is rich at idle, well all the fuel injector flow numbers inthe pcm are for 58 kpa all the way across from what i see. on my car i noticed that idle is about 62 kpa which means the car flows more fuel but the computer thinks its flowing less. so i run rich at idle
if we adjust the IFR consistent with the rail pressure would that not help out the rich idle problems and make tuning a little easier?
