    2004/5 Dodge ECM Replacement

    Hello,

    Looks like i have to change the ECM on the engine, Customer supplied a used, known working ECM. Do i need to change the VIN to get it to work or is it plug and play? And if i need to, can i do it with HP?

    Thanks

    VIN needs to be changed in the ?new? ecm to match that of the old ecm. Not sure with HP Tuners but I do know with Smarty you need a recovery file to apply a VIN change to the ecm. Same goes with calibration change for going from manual trans to auto trans and vise versa.

    HPTuners is not capable. You will have to use a smarty recovery file, have someone bench flash it, or find someone local to you that is handy with genuine cummins software that can change it in chassis for you.
