Have a 2010 Z06 on my dyno right now with the 2bar Custom OS, ECS blower, MAF is present but I have it failed to SD.
I'm noticing the air calc mode keeps switching from Unknown to Hi Speed back and forth. I have the high speed disable at 7999 and re-enable at 8000. Not sure if this is doing anything or just a bug? MAF is failed with a CEL and set to 0hz high and low.
