PCM swap

joe_mamma · Mar 4, 2015

Hello, I'm new here, I've been searching this forum but didn't see anything on this topic. My PCM crapped out in my 2000 Ex, my question is, there is one available from a 2000 F350 near me, as long as the engine and trans are the same will this PCM work in my Excursion?

yes, L99-2001 auto PCM will work in an Exc (up to & incl 2001 model X)

thank you

Does your Ex have a glow plug control module or glow plug relay? If it has the relay, then a L99-01 Federal Super Duty PCM (DPC-422) will work. If it has a glow plug control module, then you will need a PCM from a L00-01 Excursion, or L99-01 California Super Duty (DPC-452).

Good point, I knew there was something different on the EXES. Don't catch Dave in a mistake very often. In fact, I think this is one since I have heard of Swamps.

Mine has the relay not the module. When I pulled the computer it had a reman DPC-432

..LOL

which is why I keep my mouth shut a lot!

(I *think* that the GPCM didn't show up until 02)

I think some 01s were the first year. We have a 01 EX in right now with a gpcm anyway, but I can't say for 100% that some 00s didn't have them either.

To many little changes on some of the Cali models etc...

Very strange... That is a hybrid early and late 1999 California PCM. Also a really early model 2000 Excursion could have that.

It should have the glow plug relay with a shunt on it (just like the Cali model 1997 trucks had).

You can actually use tunes for a DPC-422 on that though with some modification to the relay.

I always have to think twice before responding to PCM code questions. Soooo many combinations out there...

BTW, Late 2000 and 2001 model Excursions had the GPCM, and a DPC-452 PCM code. Same as 2000-2001 Cali model trucks. The EX codes were AXD and EBM, respectively.

If I'm able to get this F350 PCM will I have to get it flashed for my X? Also Oreilley"s has the same reman(dpc-432) for $250 but its unprogrammed, is there any companies that will flash it without the vehicle? The dealer by me wants it installed and delivered to flash it and I would rather not load this beast up if I don't have to.

We can flash it.

You can order the flash from HERE.
