2011 F250 truck i just did a complete 2015 engine/ turbo/ fuel system swap. 2011 harness.
HP tuners gives me checksum error when I try to read the file from my truck.
Can anybody help me out with a tune to make this work?
Truck had weight reduction when i got it. I have access to a 2015 truck with similar mods, but I'm not sure if HPT will read that file either.
I can also program with Ford software, but I'm hesitant until i know the original weight reduction file is saved for sure.
Thoughts?
