2008 Powerstroke SCT Livewire Issues DTC's , Limp Pedal
I installed the DPF/CAT delete and SCT livewire on my 2008 F250 CC 4x4 6.4L about 2 months ago. No issues until today. I have had to reset the air flow sensor numerous times after full throttle acceleration and I know I need the cold air kit..its coming. But today, I pulled out of a parking lot and accelerated, the truck went in to an idle mode and the check engine icon showed up. I found that if I turned the ignition off and restarted, I could go 100 feet or 5 miles, no certain pattern before it did it again. Went back to stock tune and cleared it all up but no dpf so I had to retune. Same issue again. Talked to Erin at Rudys where I bought the kit and he told me I was the 4th truck today with this issue. Found out that if I activated the tow/haul switch, I could run the truck. It ran rough but I made it home. Erin suggested tuning with the Trans only file and I did and it is running fine now. Definite problem with programming. During all of this, I found some DTC codes: U0115, U0110, U0105, U0100..
I also found some strategy codes: FS0K30 AND TQJE5 and have no idea what these are? Anyone else heard of these issues??
