    The Injector timing vs RPM values differ from HP Tuners and Tunercat. Has me confused. Please clarify or explain.

    I believe the difference is efilive calculates over 720 degree rotation. hpt/tunercat is 360. thats why efilive values are double.

    as long as you bare that in mind when working with the 2 softwares you can adjust for it.

    We might have the scaling wrong too

    Edit: Just checked the scaling, I think we have it correct.

    If I make a 10 degree change in Tunercat, flash the module and read it back with EFI Live the change is 20 degrees. Could it be that EFI has this as crank degrees and the others may not have it converted so theirs displays cam degrees?

    In my opinion from a usage standpoint, (regarding crank degrees from any cam spec card) crankshaft degrees would be best suited for calibration edits.

    This may well be the case.

    I moved this thread to Gen IV where it makes more sense.
