Just a little info on the FICM. The job of the FICM is to take the 12v from the battery and quadruple it to 48v to fire the injectors. International used to mount the FICM in a different location but Ford chose to mount it nearly on the drivers side valve cover where it is subjected to tons of heat/cool cycles and vibration. Consequently the soldering on the boards in the FICM begins to crack and your 48v starts to slowly drop. Undiagnosed at startup when the FICM is only putting out <45v you start destroying your injectors. If you own a 6.0 the one thing you do need is an Edge Insight so you can watch your FICM voltage constantly...... Care to take a guess why I know all of this info?


Full synthetic oil changes every 5k, fuel filters every 10k, and keep and eye on the difference in temp between oil and coolant. Once it creeps up to 15 degrees or so it's time for a new oil cooler.

Scangauge will work as well. Just not the same nice colors. Other than the triple gauge pod on the pillar I monitor things with a scangauge. Of the 4 available things I can monitor at once one is battery voltage and FICM voltage.

I use a scan gauge, too. I monitor oil temp, coolant temp, FICM voltage and main injector pressure. I have 120,000 on my 06 Power stroke and have had 2 FICMS. I'm still on the original injectors.

I read the court case documents that were filed when Ford sued Navistar. One of the statements that I remember is that Ford said the 6.0 had the highest recall costs of any engine they've ever used. They had a large number of recalls and the average cost was over $1000 per unit.

Navistar claims that Ford modified the engines to produce torque and HP that were beyond the design limits. It was originally designed as a 300 hp engine and Ford tuned it to 340 hp.
