FICM compatability

[mr.c]

The dealer reflashed my '04 F350 6.0L after they told me that they wouldn't. I took it in with the buzz flash and it left without the buzz flash and a huge loss of power and about a mpg loss. My Autoengineuity scanner shows a VXBC9N8 calibration. I assume that is the inductive heat flash. I am interested in your FICM tuning so that I can get back the truck that I bought that had power. I am not interested in modding the truck. I just want the original power back. The truck is completely stock and it will probably remain so. It is a 11/03 manufacture date. I bought a spare FICM a couple of days ago. It is from a '06. Can that FICM work in my '04 with your flash? Or have I wasted some money?

[Jeremy]

Any FICM for 03-07 will work. So just send your new one to Bill and He'll flash it and send it back to you. I think you'll be suprised how much power has been flashed away since 11 of 2003....your orginal build date.

[Jackpine]

Bill says the '06 FICM should be a problem to reflash. :D

Corey, did you mean to say this? Somehow, it seems an odd way to answer. Perhaps you meant "shouldn't"?

groovey chick how long does it take to get a ficm back from programming? my ficm went bad and im looking for a later model used one (06-07 only because its newer and might not go bad as fast as say a 03model) and i would like to get it hopped up instead of fords detuned flashes. also any leads on ficms? does php sell ficms already tuned.

Unfortunately, we do not have any FICMs available at this time. Your best bet is to go on line and check Craig's List or some of the online salvage yards.

FICM turnaround is usually same day or at worst 24 hours.

Take care.

Hi, was looking at a few FICM's on ebay just out intrest to see how much $$ they are, most vendors say you have to send your PCM to them to '' marry up " to the FICM (or vice versa) which makes me think you cannot simply go to the bone yard and grab a FICM and put it in your truck.

I was going to do what the first person in this thread did, buy a spare FICM and send it off to be reprogrammed so I dont lay up my truck but now Im unsure. I was going to try and get a early (03-04) unit thinking it might not have been reflashed by Ford and try it first but Im afraid I'll mess some costly electronics up.

My buddy owns a wrecking yard and aways gives me first pick on new arrivals and says I can have a FICM for a $100 any year which I thought I would install first to try for fun but like I said earlier Im unsure if that can be done without problems.

They can be mixed and matched. There will be a code thrown saying the ficm doesn't match the pcm, but it doesn't set the check engine light nor cause any problems at all.

anyone know what a amz2al09 ficm would be? I know its for a 04 engine and probably is pre inductive heating, pre post buzz.

I might send that one in for a program as testing shows it appears to be a good ficm.

My problem is the shiping back and forth from Canada to the U.S

Whats typical turn around time on ficms?

[Power Hungry]

Usually 24 hours on FICMs (not including shipping) but with all the medical stuff going on we got a bit backed up and had a few FICMs here for a couple days.

I am finishing up the new hybrid FICM files to eliminate the nasty, aggressive IH strategy and use the newer, gentler strategy. I've got a couple local guys that are going to be testing and if all goes well we'll be releasing it to the mass public.

My advice, hang out a couple weeks until the testing is done. You might be glad you did. :)

[sonic blue l]

sounds good to me, besides gives me a bit of time to check out the shiping.

So far what i have found does not seem to bad to ship it to you guys. Shipping to would be about 7-10 days and probably the same back. Probably just drive there quicker, lol.

I would not care if mine sat for awhile as it would be an extra anyway.

Can you test ficms to make sure they are good before you program them? For the guys who are buying at a wreckers this may be a good option.

I know when they are bad they smoke the dc/dc convertor but i have never actually opened one up to take a look. I might have to crack one open and take a look see.

[Power Hungry]

I don't have the ability to test the FICMs, but as I understand it there is a common problem with them cracking the solder joints. I have some pictures somewhere of the components that are having the problem... just can't seem to find them right now. As soon as I locate them, I'll post them.

In the mean time, if you open the FICM up they are very easy to spot. Next to the high current connecting posts, there are 4 wirewound, current limiting resistors laying right next to each other. They are brown and are bigger than any of the other resistors. These develop solder fractures and result in decreased voltage output. In many cases, resoldering these will bring the FICM back to life.

Again, I'll post pics as soon as I find where I put them.

Take care.

I have been running the FICM that you reprogammed for me and the truck ran better but not as good as before the dealer flashed away my power. I decided to get another pcm/ecm and send that to you to program them back to the strategy that the truck came with. I have had a incompatibilty code since I put in the PHP programmed FICM. The first pcm/ecm that I got was from a '03 and I put it in to check what program that it had. My AutoEgineuity scanner showed some really wierd numbers. The program strategy number was bracketed with several y's with 2 dots over the top of them. I do not know what the CVN number is that shows up under the CAL number which is the strategy number. Anyway this pcm showed a 0 for a number. The original pcm showed 28C7D90 for the CVN.
I tried driving the truck with the different pcm and there was no tow/haul mode. The seller of the unit had listed it as for an automatic. It probably wasn't. So I bought another used pcm from an '04. That was delivered today and I put it in the truck to check to see what the strategy was. It was VXBC9N8.HEX. The same as what was current in the truck after the dealer flashed it. It showed a different CVN number 21F261D. I decided to take it for a quick drive. I felt a difference just driving it across the yard to get to the road. Very responsive to throttle. I got to the road and showered down on it and the truck took off like unleashed beagles. My truck is a F350 crew cab long bed dually with a topper. 3.73 rear gear and stock size tires (16"). A heavy truck. When it came up on boost it lit up the tires and lit them again on the second gear shift. There was a good bit of black smoke for about 50' . Thirty pounds of boost as it had before swapping pcm's. Showering down on it at 20-30 mph still resulted in tire spin and some black smoke. The power was as good as when the truck was new. I don't remember all of the smoke however.
I have a couple of questions. How could a pcm with the same VXBC9N8.HEX strategy perform so differently? What is the CVN number under truck identity? That number was different. 21F261D in this pcm and 28C7D90 for my oridinal pcm.
I still had the imcompatibility code that comes up for this unit as well. I still am planning on sending you a pcm and a new ficm for you to reprogram back to original (as sold) specs. I was going to send the replacement unit and keep the original pcm as is but after driving the truck with the spare pcm, I am not so sure. Am I in any danger of hurting the engine with this spare pcm that makes good power? Fuel mileage is an unknown on this unit since I just got it this afternoon.

[Jeremy]

The second PCM you bought could have a program on it. What year is your truck? build date?

The first PCM you bought would be for an auto if it had three connectors on it. The six speed PCM has two.

[mr.c]

My truck is an '04 with a 11/03 build date.

[cartmanea]

Agree, I'll bet the second PCM has a custom program flashed to it.

[Power Hungry]

Definitely sounds like a modified ECM. The missing strategy information is usually a pretty good sign.

[mr.c]

Bill: The one with the missing strategy number was the 2003 ecm. It didn't run very well and there was no tow/haul. I did some searching and found the CVN is calibration verification number. The '03 ecm showed a 0 for that.
The ecm that had good response did have a CVN.
At any rate I sent you two ecm's in case there is a problem programming the 2003 unit. I would like to use the '03 ecm if possible and leave the 2004 original ecm alone.
I do share your contempt for what the dealers are doing to our trucks. In my case I made them promise that they wouldn't flash it before I left it with them. They did it anyway. I better end this now. Getting riled up again.
You should receive a package today or tomorrow with a new FICM and 2 ECM's. Again, the second ecm is just in case there is a problem programming the '03 unit.

[Power Hungry]

No worries. We'll let you know when it shows up. :2thumbs:
