    Default 2009 lmm tuning issue

    I am trying to read the program that is on it. I connect to it and it takes 45 min to compete read which I know should only take 6 min. Then it errors out to this Click image for larger version.

    The ecm is locked with a patch, if its a DSP5 you will never get the file out because the file is stored on the flash chip and in other READ ONLY MEMORY areas.

    If it is a single tune and the patch is applied you won't get anything out of it either.

    Most likely you are attempting to read out a patched/locked file.
