Hello all,
I am pretty new to hptuners. I am trying to help a buddy who has swapped his 4l60 for a 4l80 behind a 5.3. I am trying to locate a file I can use to do a segment swap but I am not finding the correct OS.
His pcm is OS 1263008. Can anyone assist?
You can't.
That is a 3 BAR OS installed on that computer. The segment swap must be done with the stock OS. So flash back to the stock file, perform the segment swap and then re-install the 3 bar OS and copy over all the tune information.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Thank you
