    ?Writer Transfer:x7F Negative Response Code? Falcon BA XR8 BOSS 260

    Hi Guys I had this come up a couple of days ago on a write entire.
    The vehicle is a Falcon BA XR8 BOSS 260.
    Turns out that the 12 volt regulated power supply to the battery clip had slipped off during a write resulting in a low power situation hence the message box ?Writer Transfer:x7F Negative Response Code?

    On reconnecting and attempting to writre again this was sucessfull , however now when connecting the logger I only get about 6-8 pids and connot log anything else.
    All of the other PIDs are greyed out and I cannot select them again.

    Where have the PIDs gone and how do I get them back??

    Thanks

    Hi Misk yes I have. The vehicle was reflashing fine and all pids showing and logging.
    The next flash and the battery charger/power supply clip jumped off and the upload failed with the above message.
    After shutting every thing down disconnecting the battery and then reconnecting everything including the battery power supply the vehicle re-flashed , however opening the logger and 85% of the PIDS had grayed out and cannot be reloaded????

    have you tried a reload parameter in the vcm scanner?
    it might be worth going back a version. sometimes they have less pids available after an update.
