Hello, I am a new user, I have been reading up on an issue I have been having. From a cold start my truck bucks and has a poor idle like it is missing. I checked the batteries, replaced both as they were poor. I am going to check the ficm tonight after the truck cools down from the day, and if it shows good voltage from off position, through startup, and at a high idle then I think my next step would be to get a buzz test done. Some more info, there is no smoke at all, it only does it when it is cold, and clears up within 5min or so if I put it on high idle. The truck drives great, has lots of power, and starts right up perfect on a hot start.

About my truck, it is a 2005 F350 with s&b intake, arp studs, egr delete, turbo back exhaust, and a 60hp tune from a diablosport predator. It has about 140,000 miles, and I make sure to work it to keep the turbo clean lol. Oil was just changed, fuel filters changed, and also a coolant flush done.

Also I am thinking about getting a new tuner that has a display, nothing to special, mostly to turn it on a bit and display more gauges, I was thinking about the new diablosport trinity, mostly due to the cost, I like how it looks, and I don't need to break any land speed records.

Any help would be great, thanks all, this seems to be a good place for info, it is what made up my mind on getting a 6.0, and I do love it, but everything we love has quirks and needs tlc .

 

<p>You are on the right track with the FICM. It needs to stay above 45 volts at all times from KOEO, cranking, idle and WOT. If it drops below 45 at any time the FICM needs to be sent out for some lovin, the best place around is <a href="http://www.FICMrepair.com" target="_blank">www.FICMrepair.com</a> . For what it's worth I sent mine in as soon as I saw it hitting 46 volts. A good FICM will maintain 48+ volts.</p>

 

It is a shame that ford never made the voltage readable, I'd love to be able to just pull it up on a tuner and watch it. I am going to have to look at the section about rebuilding them, being an electrician I should be able too but I do hate small stuff to work on lol. What's FICMrepairs turn around time like? I use my truck for work so downtime is not good. Thanks!!

 

<p>They have a hot swap program where they will send you a rebuilt FICM and you send yours in after installing the new one, so you are only down for the time it takes to install the rebuilt FICM.</p> FICM voltage is readable on a continual basis with the use of aftermarket gauges, like the scan gauge II, or one of the smartphone apps like Dashboss for IOS devices or torque pro for android. There are also tuners that are capable of displaying gauges as well, like the Edge product line and there are others but I can't name them for you. The best tuning option for your 6.0L is SCT with custom tunes.

 

Thanks, I will have to look harder at the tuner I currently have, I never noticed a ficm reading on it. The hardest part about tuner shopping is that it never says on the websites what it will actually be able to show for gauges that I have seen. I hear everyone talking about the SCT but I don't know of any local places that sell them, I like to try and support small businesses in the area.

 

You may try finding a local diesel specialty shop in your area, they will be able to hook you up.

 

I don't know of any tuners that will read FICM voltage. I know my Predator is a great code reader and will read some live data but I'm not sure about the FICM, and I can't plug it in to check right now.

 

I know the edge line of tuners will at least the CTS line.

 

Torque is an inexpensive option. $5 for the app and $20 fire a good Bluetooth OBB2 reader and eBay. Can't beat it for the money. It doesn't read everything, like some of the sync stuff, but it reads most. Any droid smart phone or tablet will work. I don't have apple, but I have to think dashboss is the same.

 

Just bought my second 6.0L what will that droid app read exactly? The egr was replaced by ford on this truck in 2006. Truck drives perfect now but thinking of being g proactive on it.

 

There's a ford sensor file you can load with all the PIDs preloaded. I've got about 20 sensor data points loaded on mine. The only thing I've wanted that I don't think it has is icp voltage. I know it reads it because I can see the icp duty cycle %.

Off the top of my head.

Eot
Ect
Tft
Tranny temp
Icp%
Hpop pressure
Ebp
Boost
All three ficm voltages
Misfires
Egt
Iat

Download the free version ( not pro) and maybe you can see everything it reads. For $25, you can't lose.

 

Ok I checked my ficm voltage, it was 48.8 koeo, 48.5 cranking and 48.8 running at low and high idle. Thinking this means it is buzz test time. Has anyone had any luck running that hot shot in oil injector cleaner that ficmrepair.com recomends? Or any other brands that do about the same thing? Could it be just bad stiction?

 

Does anyone run 0W40 oil? Could it be a better option, winter is coming, but I know of places that run it in their fleets year round with good results.

 

Sure you can Tim. Won't do much good BUT

 

TFT and tranny temp are the same.
