7875 + 5.9 + E85 + Megasquirt

Regarding your VE table I’ve found that once in boost my VE numbers don’t change all that much from 3psi all the way up to 15-16psi. Fuel flow obviously changes but the % doesn’t. There may be 2-3% difference between low boost and high boost for a given RPM. maybe that will help you/give you more confidence when you make your fuel map. Also 11.0 target seems really rich to me for 12psi. I target 11.5 at 15psi on E non intercooled.
