Has anyone here replaced their own PCM? How dificult is it to do? Do you have to have the dealer cut new keys after you replace it? Dealer wants $800 to replace mine.. i called NAPA, they said there are 4 different possible PCM's for my truck, the two most expensive are $320. Cheapest could be $169. If i can replace it myself, i am all about saving some $$$..


Anyone tackled this before? What would be involved?

Thanks!

 

It's definitely going to have to go to the dealer for programming, I don't know how involved that would be.

 

Could I inquire as to why you need a new PCM?
I see you play with a Gryphon, is that the reason?
If yes have a dealer reflash the one you have with a file down load from the data center that matches you VIN..
Two keys are needed to do the PATS programming.
Otherwise only a shop that subscribes to FORD info access can do it.
They are few.
Good luck.

 

Pcm was diagnosed by Ford with a bad driver...the cause of my cylinder misfire on #2. Had the pcm replaces two years ago when I had a theft light blink no start issue. This go around same time my misfire showed up my a/c stopped working. Compressor won't engage. Might be related to pcm. Bluegrass I have had the Gryphon over 3.5 years same tune..I don't change the tune. I have wondered if that could be contributing to my issue. 2 PCM issues in two years makes me think something is amiss..either electrical issue or the Gryphon
