58v FICM vs. 48v

[goldfixer]

What is the advantage of the extra voltage? Is it worth spending the extra $30?

I Did mine myself for about a dollar and I can't tell a difference in starting or performance. It's cool to say you have it but that's about it IMO.

It really depends on where you're getting it I guess. You could make your FICM 58 volts with just a small $.50 resistor. The problem is the rest of the components aren't rated for the added load. There is an article here and on TheDieselGarage.com that goes over what is needed to convert one to 58v. I have done a few. It's a pain to do it right. Far more than $30 would even come close to covering, except maybe in China.

I'll see if I can find that link. There are a few guys on here that sell the 58v units I think. Maybe they know more about it than I do. I didn't notice any improvements to mine at 58v. But mine ran perfect before I changed it.

I am showing a P0611 code for the FICM in my truck. Have any of you purchased Swamp's 48v FICM?

here is one: 6.0 FICM - How to adjust the output voltage - TheDieselGarage.com

No I haven't. Sorry.

I'm a little late to the FICM party. By the time I started getting worried about them, the internet was full of fixes and "how to" guides. Swamps, I think, are the guys who pioneered the FICM fix. But I could be wrong.

As far as doing it your self is fairly easy and if you have 7 pin ficm all the components are more then capable of handling the extra load its the newer ones that don't have as high rated capacitors.
