7875 + 5.9 + E85 + Megasquirt

Great low boost mph! How is the tuning coming along? How rich is it under boost? Any chance you’re willing to share timing/fuel table snapshots?

I’m also surprised how quiet your turbo is. Sounds much different from my car!
AFR dropped to 10.1 (gas scale) under boost which can’t be possible. The motor usually drowns when it’s that rich. Not sure what is going on. Maybe O2 sensor is failing. My tuner says it’s either the E85 mix (I tested and it’s E85) or fuel pressure. When I get in front of my laptop again I’ll share my VE, AFR and Timing Tables.
