I have been given an LS1 PCM to run an LS1 Gen 3 engine but when i have connected to the PCM the config is for the Chevy 4.3L V6 engine.
I have opened a compare file from a 2002 5.7L V8 and copied the engine information like Cylinders, Firing order and engine size but i am getting back firing through the throttle on crank which tells me Im way off.... Any help would be greatly appreciated.
