    Default UNRECOGNIZED PCM Please Help!

    I just read an 07 6.7L ECM in a 3500 Ram, with OS 11620404 and CALIBRATION 55351235AU. When i open the file in V7.5 for editing it gives me an unrecognized PCM message and therefore i am unable to open any tables for editing!

    Email the file to support@efilive.com, this error means this OS has not been mapped yet.

    Yes the error is it hasn't been mapped yet.
    There is actually three factory updates for that tune, chances are the updates have been done.
    Need official EFILive help, please go here.
    For tuning support please post your questions on this forum (or other auto forums).
    Sorry if I don't respond to your PM, don't take it personal.

    When you say "chances are the udates have been" what do you mean by that? was that OS problematic in the beginning? Also i sent in the file does anyone have a time frame for when i will get the calz file back so that i can proceed with tuning?
