    ECM usage I have the access to a 2008 ECM from an LMM and was wondering if the interchange would work if I write the entire operating system and calibration with the VIN# Thanks for the help

    LMM: ECM cross reference

    Does anyone know which ECM will interchange with a 2010 2500 HD 6.6. I'd like to have the # from the ECM to cross reference. Thanks
