How long is it, there are so many. I found a bolded four digit number...has letters. Is that it? Thanks for your help, wanted to fax it in today.

 

Sticker on the PCM - three letters and a number - e.g 'DVK4'

NOT the 'P221' number, lol.

There's a post or two with pix - I'll see if I can find 'em fer ya, bud.

EDIT - here's the pix: https://www.f150online.com/forums/sh...59&postcount=9

Thanks guys, I REALLY appreciate all the help I get on this site.

 

Many thanks, just got my fax off...now the wait. I am getting my Xcal3 with canned tunes...then the custom tunes my email...cant wait to write a review about the difference in all three...stock/canned/custom. Should be interesting...at least to me.

 

Interesting to me as well. I think you'll write a great impartial review.

 

How can you tell what the number is if the sticker is gone?
I know you can't, but if I needed to what other way?

Don't all the same year have the same numbers?

 

No they do not all have the same number by year.

I think you can have the dealer run your VIN to check which factory tune/strategy code your truck is running.
