    You can try for key FFFF. If it still don`t work an lsdroid with clone flash and pin grounding will revive the pcm fully functioning.
    FFFF failed.

    Would I need to clone the exact same .ctz as a .bin for LS Droid to recover the PCM?

    I rely heavily on the TunerCats OB2, and have not ventured into the LS Droid system.

    At the risk of an EFI License, I'm tempted to flash the PCM using TunerCats - PCM Recovery. Thoughts?

    If eeprom area is busted neither of these tools can recover it. Even factory tool. I guess efi can but at a cost of an extra license if you manage to unlock it.

    The best way to recover is to use the last good full bin you have from this pcm that contain the info for the efi license.

    Take that bin and clone it either with lsdroid or pcmhammer. I think pcm hammer supports avt cable but I am not sure if it will work with pin grounding. You can give it try.

    What to do?? The (2002 Express Van) 411, OS 2156 PCM states it is a 4L80E, yet I would like to change it to a manual NV3500. The engine is a L31. I am utilizing TunerPro & OBDLink LX.
    I have a .ctz file for the Mexican L31 & manual transmission, yet it seems to be no help since it is not in .bin format.
    So, what can I do? Can the file be converted?

    The attached file is modified. The origins of the attached .bin are unknown.

    Use at your own risk.

    There is an all stock 4.8 manual bin on here that's 2156, you could segment swap it over to your original bin. Is your express van bin stock?

    I could do the seg swap for you if you like and post the bin here

    I seg swapped a bin for you. Both bin files show all stock in universal Patcher, I also deleted VATS.
    I have included all 3 bin files, the two original and the modded one along with a log file of what was changed in the attached zip.
