I'm having an issue where two different engine runs will have vastly different results. The attached log files show an example. One run is fine, tracking well to AFR values while the other the car ran rich. After going through the logs, it looks like the rich run had a greater pulse width (PW) value for the same conditions. This is easiest to see at idle where the normal file shows ~1.8 while the rich file shows ~1.9. Gamma is consistent at 100%, EGO is off, and MAP is reading the same.
So I guess the question is: What goes into the PW calculation that could change the value from one run to the next if it's not gamma or MAP?
Any help is much appreciated.
