Question regarding SAM unit in Operation and Maintenance: 450 Model, 2005-2006, diesel Posted June 26, 2018 · Report post Yes...the engine won’t know the difference. Remember, all the electronics has to be a set to be trouble free. There are companies that can “virginize” these SAM...or code everything as a set for you. I can only clone from an existing setup. I’ve never used their services, but u might want to give them a shout and see...might end up saving you time and a lot of work from swapping the entire engine setup. if you don’t care about the mileage issue, just install the used SAM, and get somebody with STAR to initialize it. I think it’ll flash the mileage and or log a code in the ecu...but the car will run. You’ll need to recode all your keys I believe.
