I was trying to see what version my computer was....Most guys have numbers like (BME6)...The only thing i can find on mine is on a sticker with a bar code and some other writing, it says ESY2 (i think)...Am i looking at the wrong thing?

 

Gtullous,

That sounds about right...you should expect it to be in a Letter/Letter/Letter/Number pattern. What is the build month on your truck? Some owners who have Jan and Feb '04 build months reported having code EAY2...could that be it?

 

Just a guess....EAY2=Job 2?

 

yep....thats the # ...EAY2....mine was built 12/03 ...how do i know if i have the latest version of upgrades installed or do they reflash the ecu only if you are having some kind of problem that calls for a reflash? or will they notify guys without the upgrades and do everyones when they become avaliable? (That last sentence was a good one hu??)...LOL...

 

Gtullous,

I'm not sure what the real differences between the different PCM versions from the factory. I don't believe that the "newer" versions are necessarily any better (or worse) than the earlier ones. I wouldn't get hung up on it unless you think your vehicle is having a problem...then discuss the issue with a service advisor to see what they say about what you can expect from a flash update. As far as I know, dealers won't reflash your PCM unless they diagnose a specific problem that calls for a flash update to fix it.
I'd love to hear more about this from forum members who has firsthand knowledge (Ford service techs...?)...
