Well I finally updated my insight today so I can read FICM, and it came back at 47V while key on/engine off, but then dropped to 33V with key on/engine on, and then ranged from 32.5 to 38 while running. I cleared the code and it popped right back.

I haven't had any symptoms at all, truck run and starts fine with no problems. Obviously the FICM is on it's way out the door, but I dont really have the cash at the time to replace it, and I am driving to Omaha tomorrow, which is about 250 miles, so will it be ok until I have the money to fix it?

Also, has anyone used Circuit Board Medics to have their FICM repaired? Their website says they only charge $325 to repair it, which beats the heck out of $700 for a new one.

I'm pretty mechanically inclined, and I watched the Circuit Board Medics video that they had on removing the FICM and it seems pretty simple, but then I hear of people having pretty high labor charges when they get these replaced. Is there anything else that I'll need to do, or just pull the FICM, ship it out, then put it back in?

I'm not getting any low voltage codes for my injectors or anything, so I assume that that is a good thing.

Thanks for the help everyone.

Thanks for the quick response! Whats the advantage of getting a 58V. Also, will I need to get new tunes for this? I was thinking I'd be closer to $1000 to replace this, so I have the cash to do it just gotta get it ordered.

One last thing, do you think I should be alright for my drive tomorrow? The ford dealer here said they can sell me a new one for $573 but if i can get a better one for $360 I'll do that.

I would get it taken care of as quickly as you can but I wouldn't panic over it yet. But you should be aware that continued low voltage can and will take out your injectors.

The 58v upgrade sends the additional voltage to the solenoids that drive the plungers for the HPO that fires the injector. One sends the plunger down, one sends it back. The additional voltage allows it to fire more rapidly with more force. This helps with cold starts and in the higher rpm. Well worth the upgrade. I wouldn't get a factory FICM with the same issues as your failed FICM.

Thanks for the help. I just got off the phone with Quick Tricks, she said she thinks I should be fine for my trip tomorrow also. I'm going to be ordering her 58v on Monday, and she said I should have it by Thursday.

I would be careful with that 58v. just think about whats going on there for a moment.

can anyone say "longevity"?

Read post #6, straight from Dave at Swamps. Can you say "no issues"? LOL!
FICM~ 48 or 58?? that is the question.....

k read further...

"now...all things being equal...forcing the FICM to output 58v instead of 48v will decrease it's life..it is an electrical component after all...."

not saying whats wrong or right but one has to think whats the appropiate option. Daily driver looking to get as many miles as possible might want to stick with 48. weekend warrior yeah sure 58 just gotta think about it

Well I just found out my FICM is 58V upon testing (freebe from the origional owner). I have put about 30k on my truck tuned, running hard, and towing. No issues! I always wondered why my truck ran better on a stock tune than other stock 6.0s! Also wondered why I am beating everyone in MPG. Also wondered why my truck starts like a gasser in the middle of the winter.

58V FICM seems to be the answer. No issues or complaints here!
