Has anyone figured out a way to properly do flex fuel on any of the factory ecus yet?

The way i look at it. Iac spark correction lower coolant threshold is the minimum temp idle spark correction can be made. So from -40 deg/c on up. There is also another scaler for the vy v6 min coolant for learning airflow which is set around 87 deg/c. So pretty much only learns airflow pretty much...

okay that looks a bit better but what is the table of "Warm Idle Spark Advance Vs Odometer Miles"?

can we also add this to the VY_V6_SC_$07_Enhanced_v1.2h please

Ok thank you I will check this week hopefully

Yes there is but then it's across the board where it adds timing

Yeah it's definitely not defined but when cold starting and idling on e85 would be nicer to actually have what's commanded

This is for 12P but should work fine in Enhanced.

I'm assuming this would be fine for 11p?

There is only this and when it's in park or neutral it pulls about 10° vs when it's in gear
