FICM Poll
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 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.

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!

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.

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