Hello
I currently have a 1998 Pontiac Trans Am LS1 T56/M6 and your MPVI Pro software.
This winter I am swapping a 4L80e transmission into the car. I purchased 12200411 (2001-2002 F-body) PCM with the 2002 F-body automatic tune (OS) in it. I am changing my engine/trans harness to a 2001-2002 A4 harness and adapting the 4L80e pigtail to it.
What exactly do I need to do in order to begin tuning the car?
Do I need to download a truck tune from say a 2003 Silverado w/ a 4L80e and have HPT modify that?
Do I need to send my 2001-2002 PCM into HPT to have it modified?
I am unsure what I need to do. Thanks for the help.
Andy
