Ok, Doc on www.ls1tech.com has helped alot of people do the 98 car to 99+ engine harness and computer swap. After you are completely done with the swap he has a file that has a fuel segment out of a 02 chevy express van, PCM 12212156, L31, to make the fuel level correct, but since everyone who I have came across that does this swap uses EFILIVE, my hptuner says invalid.
Any idea?
I also have a 4l80e transmission in this car, and found after posting a stock file from a 02 silverado with a 4l80e and a 12212156 os so I should be good to go there. I also have attached a stock auto 12212156 file to start with.
I licenced all 02 camaro/firebirds to be able to take care of this tune, am I going to need a specific pcm or can I get any fbody pcm and have it flashed to a 02 12212156 os tune?
