i am gonna do the a4 to m6 swap on my 96 z28 with and obd1 conv. i just wanted to know how i can convert the pcm to m6. i have tunner cat and eveything. Do i need to download the file off the ecu change it to maunal then re uploaded it back or can i just change it and it will up date.

 

Thats pretty much what I did. I downloaded my stock tube that was in the pcm already and and just put in a stock m6 file from a 95 t/am6 that I had already on my laptop. Thats all I did.
