First e85 pull and hit EPC, reading around 65% ethanol on the sensor. LTFT showing -9 at worst so not enough E, need to clear codes to reset LTFT% back to 0 now that main gas is out of the system. -9 for LTFT% is max to show there needs to be more ethanol (negative means add more E, positive means subtract E). Cylinder 1 still showing more knock than others, may need to check out (leftmost cylinder when looking under hood) ===For future, drive around maybe 5-10 miles slow after changing from 93 to E85 to clear lines of gas and then reset engine codes with Cobb AP to reset LTFT% back to 0 to then recalculate correctly=====
