Swamps Diesel 58v FICM

[FastFocus]

hey all, my FICM is going dead and i'm looking at Swamps for either their 48v heavy duty rebuild or the 58v ficm. i'm leaning towards the 58v but i'm looking for everyone's experience and oppinions. I've read some great things about swamps and it looks like innovative uses swamps for their ficm also. What would you all get, and those of you with the 58v ficm how do you like it?

Thanks in advance!

From everything I have read, get the 58v FICM. There doesnt appear to be any negatives to it and I would get it with a tune. It is next on my upgrade list. Some may say that you cant tow with a 58v FICM but that isnt true.

the tune is an extra $150, and from what i've read its not really worth it with stock injectors. If i upgrade the sticks, the largest i'll go is either 150cc or 190cc. which, will be a while down the road if at all.
anyone else have any info to provide? so far i think i'm almost positive i'm getting the 58v.

The tune is definitely worth it with stock injectors.

What does the tune do exactly? Will I see better mileage and throttle response with just the 58v or do I have to have the tune for that?
Can someone clarify what exactly the 58v does to benefit? I'm trying not to spend half a fortune. Mainly just need it repaired.

Not hatin on the whole 58V FICM thing, but I have been in a lot of high HP trucks running 48V FICM's with no issues or quirks... Not sure how necessary the 58V thing is?

I guess the real question is, is there any down side to a 58V change? Does it tax the charging system? Does it have any effect on wiring harness?

So in that case I feel like I should just get the 48v heavy duty rebuild with the tune.

You need the tune to see better mileage and throttle response. The 58volt mod just aids in cold starts and supposedly holds the injectors open slightly longer

There are no "real" downsides to the 58v FICM upgrade. IMO if you have to replace your current FICM, then I would recommend it. Otherwise just get your current one tuned.

I guess the only downside that I have come across so far is the fact that if you are using a CTS monitor, you wont be able to monitor actual FICM voltage because it tops out at 50.0V.
