It should be noted that I have been doing more city driving on this tank then Ive done in the past with gasoline.. my errands just worked out that way.
I emailed someone at Diablo Sport and asked them if they had an E85 preset. He said no but I could still increase the engine timing as much as I needed for the higher octane. He then told me that the programmer COULD help increase my MPGs on Ethanol BUT they would never be as high as Gasoline.
I still plan on getting a tuner anyway no matter if I use E85 or Gas.
I ran E85 in my 07 It took it from around 16 to 11.5 on the next tanks. So regular gasoline it is..
