I just tried to open a shared tune from the tune library and i got a message saying my flash scan tool doesnt recognize this pcm. The tunes i have tried to open are for 2008 lmm. I succesfully opened tune for 2007.5 and older. Is there an update that i am missing? any help would be greatly appreciated. this is the message i keep getting.

Unrecognized PCM
This version of the EFILive Tuning Tool has not been
configured to display this PCM's operating system.


This may occur if...
your PCM has been updated by a GM dealer
to fix a software problem in the PCM.
OR
you are attempting to load an EFILive custom PCM
program without installing the matching *.cal file.
OR
you are attempting to load a non-EFILive custom PCM program.

Please save this calibration's *.tun file
and email a copy of it to: support@efilive.com
so that we can add support for it.

What version of efi are you currently running?

I'm running v7.5.3 and just had the same error trying to open an LB7 dsp5 tune

Try to look in your V7 folder and go to the calibrations folder, copy them and paste them into the V7.5 folder, same directory. I heard that there was a bug for some that the calibrations didn't copy over.
