Factors affecting FI pulse width, 95 PA Ultra
What factors does the 3.8L PCM look at in setting injector pulse width?
I know that it must use coolant temperature sensor, MAF sensor, and engine RPM. Does it use manifold pressure? If so, where is the sensor? TIA Ed

Re: Factors affecting FI pulse width, 95 PA Ultra
If you have a MAF sensor, you will not have a MAP sensor. Basically the pulse width is controlled by CTS, TPS, MAF or MAP & 02. Engine rpm is not one of the factors.
