If I swap my 04 6.0 computer with another 04 computer will I need to have the truck flashed? Also if i buy a remaned computer does it need to be flashed by ford as well? Thanks.

Maybe not if it's the same pcm hardware number. Otherwise it's always a good idea.

Remember there are basically 2 different engines for the 04 model year. The 04s with the 03 engines are going to have a very different calibration.

Ok thanks. So if I have an early 04 do I need the early 04 computer? Or can I get any 04 and have it flashed?

Honestly I do not know. What I do know is the 03 6.0 used an SCP communication network and the 04+ uses the HS-CAN network. I couldn't tell you if the early 04s with an 03 engine used SCP or HS.

On your PCM is a hardware number, three letters then a dash then three numbers. Try and match it up with your new PCM to minimize any problems.

If you send me your VIN I may be able to find that info on oasis.
