Newbie here that could really use some good help.
I have a tune that is supposed to work with my 3800 SC Fiero
I wrote entire thing to PCM that I did not know the year of it.
Since it's an 04 Pontiac Grand Prix GTP engine and trans for it to work in my Fiero I am hearing that I need to use an 03 pcm. So I have a stock 03 Grand Prix GTP pcm that I want to write the calibration to but I keep getting " vehicle not licensed" with no option to license it?
My whole issue I am trying to fix with this is the Fiero will not go into reverse. Yes it goes into drive.
Any help would be much appreciated.
