The ecu my friend picked up for his engine swap project was supposed to be from the donor truck, a 99 3/4 ton with the 6.0 and 4l80e, however the ecu is from an 01 suburban with the 5.3 and 4l60e with dbw activated.
I just need the stock file from an 01 with the 6.0 and 4l80e with DBC to write over the 5.3 tune. Thank you
