Or else if you have a custom ecu make a basemap for every mixture like I did !

When I run pure water, I can do that without bugging (or paying) my tuner for a new tune. The Diablosport Trinity allows me to modify my existing AFR-correct tune with up to 10 degrees of timing advance in three different RPM ranges.

Do you mean like a variable knob for fuel and ignition timing?

Don't want to fling any dung here but why bother with E85? My tuner said that if I wanted an e85 tune that he would end up richening the mixture and lowering the fuel economy and I would go through a tank of gas a lot more quickly than I already do. Jeeps with 37" tires already have a serious drinking problem as it is.

AGREED!

The tack that I am going go take is to tune for pure petrol in the fuel tank and a second tune for WM50.

AGREED!
