I added air calc mode to my scanner to try to understand what's going on. I see it switch between normal, high speed, and unknown.
What's going on there?

Bump.
2008 E67 (TBSS)
During a WOT throttle run with SD fueling, with the MAF failed (correctly), High-RPM mode disabled, etc. I see the Air Calc Mode PID shows normal until about 4,200 rpm then jumps between "Hi Speed" and "Unknown" until the shift brings it back below 4,200 rpm.
Normal?
