Do you guys think that I will be able to make 200 miles on a full tank of E-85 with the coyote? All highway driving, going to be 70 and 75 mph this trip.
My flex fuel tune is from Shaun at AED. It will allow me to fill up with E-85 or gasoline and the computer will automatically adjust the fueling and spark. If you run into a situation where you can't find E-85, you can fill up with gasoline and the computer will adjust accordingly. At least for the performance variant of his tune, gasoline has a max timing at around 27 degrees at WOT. E-85 has a max timing around 31 or 32 degrees at WOT. He also gives a drag version of the flex fuel tune, which is designed around E-85 only, which has max WOT timing a little higher than the performance flex fuel version.
