Ford ecms are reprogrammable, replacement Ford ecms do require programming before they will function. The ecm you purchased may need to be progrmmed. Is it a Ford unit? Dan.

New and reman ECMs need to be programmed. Junk yard and otherwise used ECMs usually have the original program in them and should run similar engines/drivelines. If it's initialized you might be able to dump a semi-custom tune into it, otherwise you need to have the deal upload your calibration.

(If you have an interface, motorcraft offers a 3 day trial for about $15 that should have the flash program and as built data you need.)

2002 Superduty did not have PATS keys, so that's not the issue. I bet it needs to be programmed.
