Is a flex fuel tune possible with a Gen 1 Coyote Ford Racing Control Pack?
Yes
Actually the FRPP for gen 1 does not seem to trick into FF. I have been trying for a year now and no dice. No refueling threshold trigger since the tank in decoupled from the control pack on return fueling. Maybe there?s some crazy way outside of the know strategy to trick the car into it.
Gen 2 does it, just click enable. It will calculate on startup, runs rough a few seconds on E85 then comes around. Possible gen 1 is the same way.
