I still plan to run methanol in the tank too. I ended up ordering three jets that I hope are sized for 50/50, washer fluid and pure water. I will just swap jet and tune when I swap the tank contents.
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.
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.
The tack that I am going go take is to tune for pure petrol in the fuel tank and a second tune for WM50.
