L31 mexican bins 2001-2007

[Fast355]

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.
