Question on loading a tune... Ok, so I bought my car from Texas and live in Mi. Quite a difference in temps between the two states. I upgraded from a LS6 intake and stock TB/Fuelrails to the FAST 90/NW 90 and FAST fuel rails at the beginning of the year.
I took my car in to have it tuned and something is not right after. Before they installed the new tune, they saved the original tune to CD.
When I start my car now with the new tune, during acceleration (driving or in park), she backfires, and the car wants to die out. She is spewing fuel, and smells real bad. So, the new tune on the PCM is giving me too much fuel, correct?
Without hooking up a fuel gauge, it's apparant that she is getting too much fuel, as she smells REAL rich!
So, what I want to do is load the OLD tune, the original tune from Texas Speed back onto the ride.
What EXACTLY do I need to purchase to do this?
I have the laptop already...
What software will take the tune from disk and put it back into my PCM?
I appreciate all info and advice!
Thanks a buch! ~S

It depends what software the shop used to read amd save the tune. It will save it in that software's file format and can olly be flashed back in with that software and cable. What is the extension of the file on the CD?
