    Default Unrecognised PCM

    I'm trying to tune a 08 5500 C&C but it keeps telling me the PCM is unrecognised. The OS is 11610501, is there another way for me to tune this truck. Thanks

    Can you please read your ECM, and save your file as a .ctz and email it to me. I'll then look and see if we a) need to add support, or b) provide you with some direction on updating to a more recent file if yours is outdated. EFILive will not be adding support for all OS's, just the most recent updates.
