Hello All!

After recent posts and some serious pondering before another major road trip with the family this year, I have a question:

How many of you HAVE already replaced/repaired/modded your FICM on your 6.0 diesel Excursion?

Thanks!

 

I have a 2nd ficm from a 06 for testing and was going to send it in for programing, after more results/test's are in from fte...

 

I had mine repaired on my F-250 last fall, not an Excursion but a 6.0L nonetheless. Pretty simple to get in there and replace it!

Cheers

 

Unless the prior owner had it replaced mine has never been done.

 

I replaced mine last year. Roughly 130k when it went bad. Didn't flat out fail but it was running rough and failed checks so I got another one from swamps. It wasn't cheap but it's running good.

 

Replaced mine at about 100K. It didn't completely fail before replacement, but went from 40V to 20V in a couple of weeks.

 

Replaced mine last summer with an Inovative 48v. Big difference.

 

I was on a month and a half long trip when mine started to fail in Vegas, took it out and sent it to ficm repair to be fixed, showed no signs of failure before leaving. It will fail when you need it, at least mine did!

I would take it out when its convenient for you not when IT wants attention!

Just my 2cw

Edit: This was on the 2005 at 78000 miles, bought the truck new.

 

mine was repaired under warranty according to my oasis. The FICM was replaced and the ECU flashed to the buzztune.

 

Seemingly, there are only two kinds of FICM's - those that HAVE failed and those that WILL fail. In fact, an increasing percentage of our customers are sending in their FICM's as a preventative maintenance for exactly the reason the OP suggested - peace of mind. Of course, having the possibility of better fuel economy with one of the PHP tunes that we can now apply doesn't hurt the ol' pocketbook at the pump either.

While many that come into our shop have the aggressive heat induction tune on them (which clearly hasn't helped their cause and may well be the reason for the failure to begin with), many don't as well.

We always tell people to seriously consider installing a heat shield under their module so that the heat from the engine goes up and around (instead of through) the module and keep a close eye on both their batteries and their alternator(s).

Glad to have helped you out, jdw1!

 

Ed, mine is on its way from Jeremy at Empire Diesel down in Texas. I told him I had heard about you on this site. Funny stuff.

 

We'll be on the lookout for it! Thanks!!

 

132k on my 2005 and it's the original. The guys at Innovative taught me how to test it last time I was in there, and so far it's doing it's job. I'm sure it's days are numbered, but if it's not broken I'm not fixing.

 

So far still on the stock one. Usually stays at 48v, on occasion it will fluctuate in the 47's with a quick dip to 46.5. Probably starting to die.

 

No, yours is perfectly fine. 46.5v is within normal spec.
