E85 GTI EPC (LPFP Cuts) Second attempt at WOT with a GTI with only HPFP and E85 OTS EQT tune, EPC so LPFP is starving the HPFP
|
e85-2nd-epc 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=====

HPFP 93oct pull with all logging After HPFP upgrade install. Seems to be completely clean log, full throttle and full boost with zero issues seem and LTFT at 0. This should be proof that the HPFP install went fine and I'm just having issues with the E85 OTS tune from the start. Hopefully when I switch back to 93 HPFP that I don't have issues and then can put in the upgraded LPFP to try E85 again (would hate to have to replace injectors or anything else there)
