FICM repair is a sponsor here. Obviously I can not offer services here as it would be a conflict of interest. FWIW, they have a great track record.

I disagree with bismic about the 58V mod myself... there have been dyno proven increases of around 40 rwhp. The quicker response on the FICM leads to slightly more timing and a little extra HP. Though, I suppose if you had a great working FICM you wouldn't notice as much of an improvement. I will be doing one myself and trying it out soon. Need to upgrade my soldering iron soon here first.

 

it makes sence that a higher votlage would mean more heat. you know what i got a spare ficm i should probobly have a high performace one and a better than stock one. LOL. has any one ever had any problems with their 58 volt?

 

Yes. There have been a few.

Attached is a picture of a Swamps 58V FICM. It's also worth noting it's only been a FEW cases of this and there have been TONS of these done by Swamps.

You can of course just leave it 48V and have it tuned electronically. I'm going to try both on separate FICM's.

 

HOLY S%!#. yeah that looks bad. when that happens i can imagine it fries other things as well. id think for a mild stock truck like mine 58 would be ok. i think i will stick to 48. but first i need to test my truck. these 12 hr days leave me no time

 

Swamps has been great about warrantying their work though. I know one of those cases I read about they paid to have the guys truck towed to the nearest Ford dealer and paid for a brand new FICM to get him back on the road again. And, again, it's only happened a couple of times or so.

I've got a good 7 pin here that I'm going to hopefully tune up using the gryphon from Bill @ Power hungry, and I've got a good 4 pin I'm going to 58V mod and see how I like each.

 

now is swamps a buisenes? i have a cheap scanner from matco and and when this happened my scanner said no codes avalible. is there a scanner that will read it or do i have to go back to ford?

is swamps a buisnes?. what type of scanner would i need to get to read my truck codes . cause my cheap matco one wont do it

 

Swamps Diesel is indeed a business. They're very popular with the 7.3 crowd, but they repair and upgrade a TON of FICM's. They do the 58V mods that Innovative sells on their sites, and Innovative does FICM tuning for Swamps, that they sell.

I really need to start being more specific when I say scanner. In my eyes, there are code readers and there are scanners. A true scanner is going to be some sort of software based tool, like an IDS, or AutoEnginuity, which can do more than just read codes, they can do all sorts of things. AE is one of the best bang for the buck software packages out there. $350, but you need a labtop. With that, you can do all sorts of things. You can monitor every onboard computer function, including PCM, ECM, TCM, ABS codes etc... You can sit in the driveway with the truck running and cycle the turbo vanes up and down. You can do an injector buzz test, cylinder contribution test, etc... very powerful considering the relatively low cost.

Now a code reader, is just that. Most of the cheap one's wont read ABS codes either, that's a separate reader too. Some of the high end one's do both.

 

yeah thats for shure i got the 150 dollar one and it works great for cars, but isnt worth **** on my rig. i will see what my snapon rep can hook me up with. if i find the ficm bad and it gets replaced what are the odds that im still gonna half to change injectors, or is that a loaded what if question?

Ok i just checked the battery voltage on both seperate. They both got more than 400 cca. So i cleaned the terminals checked the wires. When i tested the ficm with the key on i got 48.90. Durring start up 47.80. While running i got 47.50 for the lowest. What do you guys think?

Here is another question thats way out there did the repair shop rape me and the whole problem could be a skrewed up icp sensor?

 

I can't believe we haven't asked yet, but what year is your truck?

 

I didn't say that the 58V mod didn't provide some performance gains. I just said they were small. You can get those same gains w/ the 40HP Atlas Tune from PHP (love mine) without the extra heat load. I agree that the number of failures are not huge, but heat does hurt longevity. My goal for longevity is measured in many years and hundreds of thousands of miles, others have different priorities - not better or worse, just different.

Ed at FICM repair is authorized to install the PHP tunes after he repairs the FICM's. That is the better way to go IMO. That being said, Swamps is a class act, but if you give Ed a call and just see how much he knows and how good his ciustomer service is, you will be hard pressed to want to send the unit anywhere else.

BTW, I still think post #7 applies to you, but can't even tell if you read it - !

Also - it is unfortunately a somewhat common issue to see FICM's fail and still be reporting good voltages. That being said, underperforming battery/electrical systems have been a root condition of MANY problems.
