I am having a little issue with commanded AFR Vs. actual AFR. I use the latest custom O.S., I have the whole AFR map set at 14.63:1 escept for the last few columns for WOT. During part throttle driving I noticed some cells On my Wideband map are showing leaner then they should be Most cells are 14.7-15:1 But alot of cells are running close to 15.5 or higher!
What could cause this? My O2's are working properly... The only thing I can think of is I have my Short pulse on the injectors subtracting .3 Volts under a commanded 1.5 MS.(I run 96 lb injectors and have to do this to get off throttle AFR lean enough.
Does the computer not see that I am subracting Voltage from the injector under a 1.5 MS???? Could that why I am seeing a leaner then commanded AFR???
What are your thoughts??:Eyecrazy:
