Reprogramming froma 4l80e to 4l60e
Yep you read the title right I am swapping from the 80e to the 60e, I know its backwards.
Heres what I have 2001 LQ4 6.0l/80e computer. 2001 60e wiring harness and transmission.
I have the 2001 5.3L pcm that used to control the 4l60e and have the files for both computers.........Now how do I make the LQ4 computer control the 60e?????
Can I just copy/paste all the trans files from the 5.3L pcm to the 6.0l pcm?
I tried diggin through here and the HPTuners forums but I couldn`t find a definite answer. Tuning , but hey I figured out how to get rid of that pesky speed limiter and ! rear o2`s

I never had the 4l80e, I upgraded a car that was running a 5.3L to the 6.0L so I kept the 60e that was in it along with the 60e wiring. The computer that was in the car had already been retuned for the 5.3 and I got a factory tune 6.0L PCM with the new motor so I figured I would use it instead of having to tweak all the engine management tables to run the 6.0L. Plus then I have the 5.3L computer to go along with the 5.3 in case I decide to drop it in something else.

OMG, you are making this much harder than necessary! Just adjust a few tables in the 5.3 pcm to adjust for the 6.0, and be done with it. You are REALLY making the swap much harder than it needs to be. A transmission segment swap that someone else has to do for you will be MUCH more time consuming than a few minor tweaks to the 5.3 pcm that you could do yourself in less time than it took me to type this.

The reason that I didn`t just retune the 5.3L PCM to run the 6.0L is that I am probably going to drop a 5.3L and 4L60E into another car. So if I retune that PCM I will end up with the 6.0L/4L80E PCM sitting there and it would need to be reprogrammed to run a 60e anyway. In reality either I figure out how to do a segment swap now or later.

I had another thought tonight. Can I just do a complete re-flash and flash the 6.0L PCM with the 5.3L program? Then I would have to correct the engine management side, but then both of my PCM`s could run the 4l60e right?
The 5.3L PCM was from a tahoe and the 6.0L was from a GMC 1500 pickup.
