FICM 48v or 58v?

What are if any the disadvantages to bumping my ficm up to 58v? Ive read a few cons to doing the upgrade but I wanted to hear from my fellow PSN members that might have some technical insight.

the ones ive seen have had noting but peoblems, they like to eat injectors but thats just what ive seen with the 58v ficm

My truck has a Swamps 58vlt FICM, that the orig owner had installed. It is at 162k+ and just replaces #7 injector last week. Testing the FICM, it puts out 54-55 volts during key, starting and then idling. I have used archoil 9100 and has HSS in it. I cannot give insight on bow the truck ran before the Swamps FICM. From my reading OEM injectors start going out between 150-200k miles. Truck runs great and starts easy in cold weather.

I myself would go with 48 volts but that's me.
I have heard it does start better and is better when cold.
Just seems to me another 10 volts=more coil heat every cycle?

350k on my 04 with the .58v ficm and so far not one problem. I'd recommend doing it. My fuel mpg increased slightly, starts much easier in cold, I'm in Canada where it is stupid cold for 6 months out of the yr. -40c before windchill. And that is my snow plow truck. I got my from g&j diesel in billings mt.

I heard and it makes sense but it came from a Ford engineer that the main disadvantage of a 58V is with the added voltage. You can expect added electrical wear on the injectors.

I'm a big fan of the Bullet Proof Diesel selectable one. I have been running it on the 53v setting for almost 2 years. I have had the truck since new and it's still on its original injectors it has 160k on the clock and like 3900hrs. Crisp starts and good performance from what I have seen.

I'm not an electrical expert but at work when they modify components such a solenoids they often boost the voltage and this actually reduces their amp draw and its my understanding that its high amps that build heat.

x2 for swamp's FICM 58v.

radioflyer....x2 for Swamps? explain please?

Pretty sure he means second vote for Swamps 58v version.

I too, was also under the understanding like Term3 stated that for the type of load an injector places on a system that as voltage goes up amperage goes down. Same theory in 24v winches and 240v shop tools.

There is no measurable amperage at these injector coils. They are micro electro-magnets, I like the 53 volt idea. The additional voltage surely speeds up the spool valve

The components of an OEM FICM aren't designed to run at 58v.

Bulletproof Diesel is the way to go.

Yep...not a actual "x2".

I don't understand how increased voltage can result in lower current. Amps of current in a complete electrical circuit is voltage in divided by total resistance of the circuit. If voltage goes up, and resistance stays the same, current has to increase, according to Ohm's law. Unless there's something in this particular application that I'm missing?

Well if you compare for example electric motors same HP one in 12 volts the other 24 volts the later is always indicated as a lower amp draw. At work on our cavern storage EBV's our I&E department often speed up solenoid response by boosting voltage in order to get these huge valves that weigh three times the weight of my truck to slam close when needed. Like I said I'm no electrical engineer and this stuff is way over my head.

Ok well I got my Bpd FICM power supply in and now I'm throwing codes please point me in the right direction. P0611 (soft code for running over perimeters?) p0683 u0306 p1000 how do I correct these?

Zmann
01-12-2014, 11:47 PM
don't worry about the 1000 is cause you unhooked power the 0611 is over voltage from the new ficm no problems there

the rest I need to look up

Zmann
01-12-2014, 11:51 PM
the u code is a software incompatibility not a biggie did u buy a whole FICM ?
the other is a glow plug code IDK why you have that

the 1000 will clear after a while the 0611 and the software code will stay
the GP ??

I bought just the power supply, the logic board is the org. I don't understand the logic board was still good the power supply was toast I'm running the 58v side of the power supply I have no idea why the PCM. And glow plug code?!?

Zmann
01-12-2014, 11:57 PM
are you sure you didn't have the FICM software code before ?

u didn't have a atlas flash or anything to the logic side ?

are any actual CEL codes or just soft ? like the 1000 and 0611

txdieselmech84
01-13-2014, 12:44 AM
No CEL codes just the ones I listed I haven't had the FICM tuned or anything I'm kinda puzzled as to what's going on.

Zmann
01-13-2014, 12:57 AM
so none of the codes set the CEL light on the dash ?

are you sure you had no codes before the FICM ?

I have the 0611 anyntime i check for DTCs....

My bad yes the check engine light came on it's been on since the FICM went bad

Zmann
01-13-2014, 10:16 PM
interesting because none of the FICM codes nor the 1000 would throw a CEL light
as far as I know but the Glow plug module may ?

had you ever scanned for codes before you replaced the FICM ?

txdieselmech84
01-13-2014, 10:26 PM
Yes that is how I found out it was the FICM no one ever mentioned the glow plug code. It is possible that it was there before. How do I resolve this issue Ford wanted 200 dollars just to look at the truck!

The load on a coil on a transformer or solenoid (inductive load) can not be determined using just a simple ohms law calculation as it is not a purely resistance load. If you look up resistance and induced loads it gets a little more confusing on figuring out amp draw.

You have it backwards. If voltage increases with the same resistance, the amperage will decrease. Hence why pool pump motors, for example, draw twice as many amps while running on 115V as opposed to 230V.

He has it correct as far as ohms law goes relating to resistance type loads. Go to any ohm law calculator and this will prove true. An induction type load is completely different and you can not simply calculate it based on ohms and voltage. Dual voltage motors are tapped differently when wiring them and that is why you get less current draw at higher voltage.

there is a chance it is your glow plug module but short of swapping it out I think testing it on the truck was reported to be a pain ,, they say check the connectors it's on the pass side valve cover up front
