Also, if for whatever reason I don't have the E85 flash I assume I don't have the timing advance adjustments either to take full advantage of running E85.
I got the flash and had to adjust my AFR target cells to high 70's to get high 12's:1. At a 50 setting it ran too rich. The DME sheet said "e85 G" so I assume it is the right one.

I'm sure that would drop a bit in Map 4 with meth. My boost target is also 2 psi lower without meth. I included fuel pressure because I'm running the new booster pump if anyone was interested. Prior to putting the booster pump, I was getting low pressure codes running 60% or higher Ethanol content.

At the time of this run, Ethanol % was at 81.2% according to my Flex Fuel sensor.


What fuel pressure are you logging there, low or high? Which one is debug byte 4?
