After long research for a very long time, finally here are the bins for L31 engine exported to Mexico running ls1 style PCM.
Managed to get for 2001-2007 MY with different OS being used.
The files are segment extracted, Later I can make full binaries, but these can be used for segment swapping.
I have not downloaded them yet, were you able to find a 2003+ for an automatic? I have never been able to get my segment swapped manual to 4L80E to correctly operate the P/N vs Drive idle airflow and idle speed tables. It thinks it is always in gear. It runs great, never stalls, it is just not a factory smooth transition into or out of gear because the PCM does not add or remove airflow for the transition until the idle speed logic has time to react. I have also never been able to get the flex fuel logic to work with the 4x crank signal. I have always been told that there was both a 3x 4.3L and 4x 5.7L flex fuel calibration out there too but never been able to find one.Originally Posted by kur4o

All files are manual trans, but a segment swap might cure some of the issues. The only change I could find is speedo calibration, and one file have 2 different system segments.
There is a file for 7603 OS, with that we can copy all the tables you want from one bin to the other. And do a full compare for differences, between the l31 and other files.
Great work! Thank you!!
Made a full bin for 7603 OS and add some files for comparison.
The xml file need to be extracted to tuner folder.
Thank you! Can anyone confirm what the wiring differences between the p01 and p59 are? Or if anyone has switched from p01 to p59? Im curious about 2 OBS trucks I have and am planning engines for them...
