Hi all - I'm helping a friend with 7.4L do some tuning in TunerPro. Coming from HPTuners, with more modern ECM's I'm a little stumped on a few things. Any help would be greatly appreciated!
PE - Something seems goofy with the PE enablement. The log file says it's going into PE, but IPW isn't reacting like I think it should. It seems to stay lean for a few seconds before richening up like it should. I don't think it's the VE table because a similar cell (RPM & MAP) in the next gear is rich like it is supposed to be. See the marked spots showing about 3500rpm in each gear. It gets richer, closer to 12.0 AFR I expected, with each gear. Any ideas?

Desired AFR - Whether CL or OL, Desired AFR seems to always wander around 12AFR. It goes into CL no problem and oscillates around 14.7AFR so I'm not sure what's going on here. Anybody know why Desired AFR is just wandering around? Is there a different desired AFR to log that actually tells what the ECM is commanding?
4L80E Shifting - Any pointers on firming up shifts? The only shift time settings I see in the BIN is Desired Shift Time Altitude Gain vs. TPS vs. Shift. What is this? This looks like something I should be looking for but looks more like a special case than base shift time settings.
