FICM Repair?

I'm in the middle of "bulletproofing" my newly bought 04 F350 (all the threads on here have been a great help in this project so thanks to all!) The heads are currently at the machine shop getting checked so I've had a little down time to double check everything and make sure I have everything ready to be reinstalled. The one thing I may have overlooked is the FICM, which I never checked the voltage on before the tear down The truck was throwing a code about one of the injectors and ran pretty rough (like it was running on 7 cylinders) prior to tear down, so I just figured it was a clogged injector or something. Well anyway after reading through the forums could this be a problem caused by the FICM? Even if its not the problem caused by the FICM should I send it to have them build it up so I can avoid future FICM failure? And if so should I consider a a PHP tune on it like the Atlas 40??

I've been looking around and haven't read too much on FICM tuning so any advice would be great cause I don't know too much about the FICM. Thanks everyone for the input.

I went with the Bulletproof Billet selectable voltage half shell FICM myself

both are local to Me and BPD doesn't have the tuning option yet but they are working with PHP to get it rolling but the Atlas 40 is a good choice or order the programmer from PHP and change it as desired

I don't know if makes it any tougher when they reflow ? so I decided on a whole new design

Another question to go along with this is when the FICM is cleaned or rebuilt, is it going to go bad again? When looking into this FICM should you go for the upgraded one or just a stock FICM? My dad's FICM went out at 63k miles so in order to make sure the part is "bulletproof" is a new FICM reliable or is it better to upgrade to the Billet selectable voltage half shell?

From what I've personally seen/repaired the resistors have cold solder joints. That's most of the problem. Capacitors have usually checked out within spec and show very low esr (0.00-0.02). Capacitors also have cold sold joints, but aren't as bad as the resistors. Once in a while I get one that was just hammered and although the major components (capacitors, resistors, transistors) read normal something else screwed up and not worth the effort to repair. A repaired ficm I personally believe will last longer than a new half shell replacement from ford. $0.02

Call and talk with Ed if you are wondering what He does when he repairs your FICMs.

I recently had mine repaired by Ed. Had the upgrade service done and the Atlas 40 put on it. I can not say enough good things about his service. From out of the truck to back in was 4 days. Truck starts much better, voltages stay constant and the Atlas 40 made a noticeable difference in the low end power. I do not have any other tunes yet though so if you are already tuned you may not notice as large of a difference.

I would recommend Ed to anyone needing a repair and I don't think I have seen anything but praise for his service. To me that says something and is why I went with him.

The FICM is likely not the issue with the injector. Typically if it is the FICM it will throw injector circuit low codes on all injectors.
