    It should be possible, log a support ticket here: https://service.efilive.com/new-ticket
    and include the appropriate trace files.

    For flashing 2022 CMF (CM2450B) stock files, try this updated version: https://forum.efilive.com/showthread...1-Beta-Release

    Note: Please read the "Known Limitations" #2 on that web page about opening CM2450B 2022 files.

    Paul 2022 Can we sniff the data going in to a 2020-2021 that locks the ecm down like 2022 and see where they are changing or adding and reverse engineer this possibly?

    Thank you.. I bought a new V3 and used V8 Scan Tune and was able to change VIN. Thanks again for all the help.

    Sniffing the bus but won't help. The ECM is locked using a digital signature. The same signing technology that keeps things like bitcoin secure. There is no way to "fool" the digital signature.

    No, not the same. More secure.The technique we used for the previous models won't work on the newer models.

    If 19-21 can't be read, how does one get a stock ctz file? Can you convert .efd to .ctz?

    Most times we can, open a support ticket and attach the *.efd file you want converted.

    Is it possible to use a 21 ECM to gain EFI Live support in a '22 Truck ? Or are there additional checksums outside of the ECM that can cause functionality issues with other modules ?
