PCMTec got me sorted on this as it was the Anti Tamper in the Whipple OS that was causing the issue. After them supplying a fix for it I was able to re-assemble the tune with the CustomOS for CAN flexfuel and everything worked out great. Thanks again

I flashed the tune back to the original read with WhippleOS and then logged it with key on engine off and did not have issues with the accelerator position reverting to a max value of 30%, it would register 100% everytime with throttle and etc torque desired matching. The accel pedal sensor values match as well with 4v on PPS Volt 1 and 2v on PPS Volt 2 everytime when you are full on the accelerator pedal. I then added just the CustomOS to the tune for canbus based flexfuel and flashed it, and in the datalog after 60-90seconds the accel pedal goes from registering 100% to a max value of 30% and the throttle went to 26% and ETC Torque Desired 535nm while the PPS Volt 1 and 2 do not change. If you key cycle it and let the ecm reset then you get 100% throttle back for another 60-90seconds. I have attached the 2 tunes as well as the datalogs. I get know check engine light or wrench light on the dash when this happens either. Hoping another set of eyes on this can make sense of it.
