    Yes, you really do need heat range 9 plugs as the tune won’t be factory after we’re done with it. Isn’t that the whole reason you bought the MPVI2 in the first place?

    You need a high quality...

    The DTCs are rear O2 catalyst-related (downpipe); you'll have to decide if you want to turn off the rear O2 sensor or disable those DTCs. I won't do that for you since it is illegal.

    The front O2 sensor was needed just to address the weird measured lambda fluctuations and has zero effect on "surging" behavior. I had zero problems with the NTK front O2 sensor on a fairly...

    Seems like more of a driver or connectivity issue to me. Have you installed the latest MPVI2 driver?

    I found and fixed an error in the low octane spark offset map. 3 cells were 3.00 degrees and they should've been -3.00 degrees. Post #45 has the updated bin.

    Curiously, overall power was a bit down up top which was unexpected because leaner lambda in that region should have resulted in...

    I’ve been describing the recent revisions fairly succinctly, so hopefully the changes will be clear when you look.

    EGTs look great, barely above 1700 degrees F (1720 max.), so component protection (CP) lambda is not the issue.
