I removed my PCM yesterday in order to ship it out for it's custom tune today.
I was wondering how many different codes Ford has already used on these trucks.
My truck is the 5.4L 3v, and it's PCM code is BME9. My build month was 10/03.
Anybody have a different code? The codes should evolve through production as they try to correct problems and make additional improvements.
Please also post engine type and build month.
In case you're not sure where the PCM is, I included the below picture taken from in front of the engine compartment. The PCM is circled in red. There is a sticker on the front of it that shows the code in bold print.
I haven't had my PCM reflashed. I believe the temp. issue and fix was identified before mine was built (at least the temp reading has been accurate).
I am curious whether those who have had reflashed done (for either the outside temp. reading problem or the check engine warnings) needed/had updated stickers added to their PCMS. Anyone?

If they do a re-flash, it should be listed on your repair receipt. If they say they did, please ask them if they make a notation on the PCM. I would sustpect that even if they are supposed to (and I am not certain that they are always supposed to), that a lot of dealers don't bother, but I certainly may be wrong. I've just never had my PCM reflashed.
Even Mike Troyer told me that on the F150 Lariat Screw that they've tested their performance packages on came with a "BME8" sticker, but the PCM had already been updated to BME9, without any notation on the PCM.
Mine is the 5.4 3v built 9/03 and the sticker says BME8. I had it reflashed awhile back (03/01/04) and I'm guessing that they didn't put a new sticker on it as it looks original. All it says on my service ticket is reprogrammed PCM per SSM17261 if anyone can make something of that, but no flash code that I can find anywhere (BME?).
Originally posted by Dusty1 My F150 was built in Feb, and the PCM 221 code is listed as EAY2. Any idea if this is the most current flash?
I started this out of pure curiosity, but maybe we'll be able to find out based on other responses...interesting that yours doesn't follow the BME# pattern. I wonder if there is any significance in that...
