93 Octane

2nd pull JST base map

260: dinner run, weirdness at high throttle, low RPM near end of log.

This is the map sent from Ken, developing a misfire above 5.5-6k RPM

Basically Stock ROM - Modified to ignore low load knock readings. Wastegate restriction pill installed - boost returned to factory values around 14lbs. Produces bucking at high boost. If gently easing into WOT, can produce smooth power delivery. CEL has not illuminated since pill was installed and boost restored. CEL used to indicated cyl1 misfire at low load (idle and cruise, vacuum), although power delivery was 99% smooth. Cyl1 compression is low. Perhaps increased boost allows fuel mixture to combust more easily resolving the misfire issue, but then why the bucking?
