Do you have a log showing ETCTP, RPM and MAF g/s...?

Try this one ... if it still does not fail the MAF and default to SD mode, then remove the "Yellow" signal wire from the MAF connector.

No worries ... glad it worked out ... had forgotten that High Speed Airmass Mode was originally set to well below idle RPM on some of the older GMPP controllers.
