Thank you everyone for your help. I want to transfer my current tune, which is a hex file, into the UTEC. The instructions clearly state this must be a txt file-- I can't just upload the hex file straight to the UTEC from what I read (maybe I can? Haven't tried it yet). I know how to upload maps-- I don't need help with that lol, but its funny none the less. What I need help with is either transferring my old opensource maps into the utec, or just tuning the utec again. Specifically, converting the AFR table into a maf voltage offset value as required by the UTEC.

I would guess this requires a completely new tune -- as the maf voltage offset is based on the base map according to the UTEC manual and won't just transfer over. Am I correct?
