I have a ls2/4l60e with a PT88mm turbo on my 1988 dodge Ram...I bought the ID1000 injectors that came with all the data and downloaded a custom OS into my 2001 Camaro computer along with a CAX file that allows changes to the minimum injector pulsewidth..I think its B9021? Either way Im nice an lean at cruising speeds but at idle it falls into the 10:1 A/Fs .. I logged an injector pul;sewidth of 2.7 so I know that's the issue, computer isn't allowing a 1.6 or lower for some reason. I have no O2 sensors, no MAF, all speed density...is there anything I'm missing? should I tweek the ID1000 data any? I can post tuning files as needed but curious if anyone else has this issue
I also have a turbo 2002 Camaro that had this same issue until I downloaded the Cax. file for B9021...Camaro is fixed but the truck still has this issue...I read on here that I could take that 2002 cax. file and rename it for the 2001 OS, is this a problem?
