Honestly, my tune is MAF only with a stock VVE, VTT, DD (100 row), Peak Torque.
Fueling is spot on at part throttle. Port injection handles fueling at WOT past what the DI can't handle (MAF curve is stock multiplied by 5%).
Spark is commanded with no funny business. The only issue I have is what I thought was phantom knock retard above 4000 RPM but it's not there on E85 so the build just won't work on 93 octane.
The next test is going back to full 93 to see just how much spark it will handle, probably 5-8 degrees, but it doesn't knock at all on E85 at 20, so I will just add it back in with the flex spark table.
I have spent weeks upon weeks perfecting the VVE only to move it away from it's relationship with VTT. Sounds crazy but at this point I think they are too interrelated to change either of them until we fully understand how they work together with torque calculation, reporting, and control. The car is doing exactly what I want it to do with all of that stock. I suppose I am essentially letting the ECM think the car is still stock and letting the port injection pick up the difference.
With that said, I am commanding stoich (EQ/Lambda 1.0) during PE fueling since I have port injection. The only other thing I haven't tried is changing the EQ Ratio Torque Model table to all 1.0 while commanding a richer PE, like 1.2 since that would correlate to the same thing I am doing commanding stoich for PE, the EQ Ratio Torque Model table never moves from the 1.0 column. Not sure there yet, a test for later to see what that will do.
