    Default 08 cab and chassis stock file

    Anyone have a stock file for a 08 cab and chassis? Got a customer with a bricked ECM, but was too cheap to buy a new one. So they bought one from the wreaking yard. Of course it's not a cab and chassis file in it, and since it doesn't have the right part number in the ECM my Witech only wants to flash a 2500 file in it.

    You need to get the P/N's off the old ECM. There will be printed on the sticker an 'E/C' code, that is what people will need to get the correct match tune.
    I no longer monitor the forum, please either post your question or create a support ticket.

    Search the Fed World document and you can get the calibration that will work for your application.

    From experience, you can use a CC file from 07, 08 and 09 in all of the model years without issue.

    Also, if the ECM is indeed bricked, it can be recovered. I wouldn't trash it.
