ok this is what i did , since e-85 is slow burning it needs more timing so i had it at 10 % + for 93 octane so i bumped it up to 14 % and went 10 point + on the fuel since you need more e-85 to burn effectently , the went to ltft and logged for 20 miles read 22 % went to enjector slope and went 20 % to small , then logged they were -2% , really runs great with supercharger
