So, my swap is slowly getting closer on the Jeep.
What I have for frankenJeep;
2003 5.3 LS from Silverado It's DBW and I have a TAC and pedal from an '03 as well.
2003 pcm (5.3/4L60E stock tune)
2005 Harness from a 6.0/4L80E Silverado
4L80E & NV242HD transfer case (from H1 Hummer)
I have thinned the harness, and removed the AC/EVAP/REAR O2's/low oil sender/oil pressure connectors.
Found 2 same os(12579405) files on tunefiledepot one is 6.0/4L80E and other is 5.3/4L60E
I could not locate another 4L80E file that was the same os as the pcm I have(12593058).
Assuming I'll be able to flash a newer os on the pcm?????
I did 2 segment swaps on the 5.3 file from the 6.0 4L80E file.
Then disabled VATS, changed all the MIL/DTC codes for the rear O2 sensors/EVAP/ to not reported.
What is the correct way disabled A/C control in the pcm?
Anything else that needs to be changed for a standalone harness config?
Talk about information overload....compared to ODB1 stuff that is.
Thanks in advance. Probably have other questions as I venture deeper down the rabbit hole.
I can post the file I'm working on if it helps?
