so I noticed today I get some timing retard at highway cruise high load before it down shifts. I'd like to try and pull some timing where this retard is happening. hpt doesn't log retard timing for my vehicle. Just total timing.
I do have access to high octane and low octain maps to adjust, I just need to cross reference where to remove a few deg. torque app will show my timing retard, and I can log it and other stuff, spit it out as an excel file, thinking I can get close enough but of course hpt spark map uses cylinder airmass g. which my other app knows nothing about(me either haha). I can log maf g/s and map kpa, stuff like that.
without just taking a wild guess, is there anyway for me to log a pid that's standard on torque, do some math's to cross reference?
having the retard pid in hpt scanner would be preferred, but I'm pretty sure you can't manually add pids right?
the pid is 2211a6 and math is (22.5*A)/256 if it's possible.
this is a hybrid yukon, and hpt has moved on from these odd ball ecm's, thankful for what I have but no chance of them adding anything for me on their end.
thanks for any thoughts
