    Default Reflashing Question

    As you can see my ECM developed a burn that tripped the 25a ECM fuse under the hood.

    I bought another ECM used. The damaged ECM is still functioning and I have saved the data from it. I want to transfer that data to the other ECM. My application is telling me I need to buy another license. Why is this necessary when I have a license for this vehicle already? What is the solution?Click image for larger version.

    The license is not VIN# specific or tune file related.

    It is specific to the actual ecm you first licensed the flashing device ( V2 or Autocal ).

    Even though its called a "VIN License" its actually a license for the ecm you flashed previously.

    The ECM has a unique identifier/serial number, and when its different regardless of the tune file or its origin requires a new VIN License for the replacement controller.

    So...what will this cost me?....seems a little frustrating when it's going in the same vehicle.

    Thanks

    Hi George,

    If you send a scanned copy of the invoice for the replacement PCM purchase, EFILive will provide a replacement VIN license free of charge.
    Send it to me at paul@efilive.com with a link to this thread so I know what it is for.

    Regards
    Paul
