Unrecognised PCM

[JoshH]

I'm trying to help a guy with a tune on an LMM. When I tried to open his stock tune I got an Unrecognised PCM error. I thought maybe it was because I didn't have an up to date version of EFI so I downloaded the newest thing I could find and updated it. I now have v7.5 build #21. Unfortunately it is doing the same thing. The strange thing is it opens the Vehicle and Calibration Identifiers along with all the Segment IDs and checksums. It just won't let me actually view the calibrations. Anyone know what could be causing my problem?

This is on an 08 LMM OS 12617083. Thanks.

Josh, you'll need the M81.bin file and that .cal file to get into the '08's. Email me if you'd like it.

Thanks Nick, but I just received it from someone else.
