I'm at a near witts end here. Possibly this is not a tune issue, but sure seems to be fixable via FRP PID LOOP correcting. It seems as though the ecm is seeing desired under and overshooting actual and over-correcting.
Does anyone have any insight? Possibly fought and conquered this issue on a lbz with dual fuelers? I was commanding 183mpa and 2800ish uS.
Thanks for any help, i sure appreciate it.
