I haven't had a chance to read and see if my 97 has this but the 2002 PCM reads fuel tank pressure voltage. Did any of you with the OBS truck conversions have to disable this from the DTC's? If I don't need this I'll disable and set the error code to 3. P0452 is the only code I'm throwing so far.
Oh, with my tach reading lower than normal, this is probably why my tranny never shifted correctly. It felt like it was staying in 1st gear. I know my RPM's were showing under 1500 when they were really around 3000.

Yeah, that's one of the side issues when jacking with the tach output, gotta jack with the shift points then. You should be able to shift manually through the gears.
Allen did mine so I don't know. I disabled the fuel voltage on the 92.

Ok Greg, I reflashed the PCM by changing the resolution to 3 and 3 and deleted the fuel canister purge solenoid and other crap I didn't need. No DTC's now and the tach works within 100 RPM now. Going to Deer Park in the morning to get the exhaust put back on and I'll be rolling if I pass inspection. LOL
