On a side note, is it possible to target 15.5 16 AFR in closed loop with a stock ecu? E85 of course. I'm sure this has been discussed before. Really just curious, I don't mind $tree fiddy per gallon of E here in Cali.
No, you can't target higher than 14.7 but you can adjust the o2 sensor scaling table to trick the ECU into running leaner in CL fueling mode.
