FICM shot?

[powercat]

Ok, I’m afraid my FICM is shot,
05 Excursion 6.0. bought it in May and had new batteries installed then.
Running a CTS and the FICM voltage is 47-48 prior to start and then when idling drops down to the low 30's and gradually works it's way back up to the 47-48 range when warm.
From what I’ve read, im guessing the FICM is shot so….

How long can i run like this before it damages the injectors or something else?
Where is the best place to get it fixed? I think I would like to get it repaired and have an FICM tune installed. I’ve read the FICMrepair.com mentioned here, is that the way to go.
Also, sometimes my monitor doesn’t turn on until I start the engine. I have to unplug it to see the FICM voltage prior to start. What’s up with that?
Thanks for the help

I'd agree that your FICM is shot, and you're damaging injectors any time the voltage is lower than 47v. There are too many variables to say for sure how long your current injectors will last if things don't change, or how much their life span has already been shortened. Bottom line is don't delay making a decision and replacing the FICM.

You have a few options for a new / repaired FICM. I, and many others, feel the best available is from Bulletproof Diesel. Their 6 phase FICM gives you the option of running 48v, 53v, or 58v. The heat sink is upgraded to dissipate heat more effectively. They use military grade hardware. And there are redundant circuits built in to keep the FICM operating in specs in the unlikely event of a hardware failure.

We have an OEM FICM in stock, let me know what you descide!!

Don't take the chance, just take care of it now. I had mine repaired by FICMrepair and was really happy with the service and the fast turn-around. I got the eco-tune on mine and it made a big difference as far as throttle response. I can't speak to mileage as I don't drive the truck every day and have not had a chance to record that yet.

I would also look into the upgraded repair for a little extra peace of mind. When I pulled out my FICM, it had a manufacturer date of 2008 and my truck is an 03 so even brand new they do not seem to last long.

thanks for the advice, what do you mean by upgraded repair?

They offer 3 repair options, the highest level comes with a 2 year warranty. I called and spoke with them before sending mine off. They are very knowledgeable and willing to talk with you to make sure your ficm is the problem. Lots of FAQ on the website too.
