(Another) FICM Tuning Question

Hey y'all, hows it going?


Well I finally got my Livewire TS installed. I'm a little broke right now but I possibly have a good job opportunity and if all goes right I'll be driving water truck for Chesapeake Energy and will actually be able to afford my truck, lol.

Anyway I was just reading the other FICM thread and I was reading about PHP. I saw the picture of one guy's set up (sorry don't know the name) and he had a 4 Pillar Pod with 3 gauges and then some sort of Edge Juice with Attitude looking unit on the bottom. Everyone seemed to indicate that it was a FICM tuner rather than a programmer. But it seriously looks just like an Edge, lol.

PHP says they have a "Gryphon FICM Tuner". Is this what was in that picture? I've been wanting a FICM Tune for a while but I always thought you had to either A) Send your FICM In and have it tuned or B) Have a SCT SF3 looking device show up at your door and use it then send it back. Is this Gryphon thing sort of like an On-The-Fly FICM Tuner? If so, how does it work? Do you recommend it?


Also another question, upon start up my FICM reads in the 30's for Volts but when I start driving it instantly goes up to about 48-49 volts. I'm just assuming since everything draws a lot of power from the obviously the FICM isn't going to get the correct amount of power. However when driving the alternator is putting out more so then it can get all of the power it needs. Is my FICM about to go out or am I right about the whole power issue? Like I said it NEVER reads under 45 volts when I'm driving or after I have driven. Just always on the first start of the day.



Thanks y'all!

If your FICM reads under 47-48 volts at anytime you have a problem. Batteries, connections or FICM.
Mine will stay at 49 while cranking with my lights on and Viair compressor running. Every other truck I've scanned with a healthy FICM is the same.

That was my truck and yes its phps ficm tuner. It is black and the edges are gray. If tou ficm is anything below 40 ford and international say to replace it. Yours need to be repaired before you hurt you injectors. Or better yet a bpd unit is a great route. Seeing as you low on money ficmrepair.com is tour next stop.

Yep that's the one I was referring to! Does it plug directly into your FICM? Is it on the fly adjustable?


And well honestly I think my alternator is starting to go. I'm always at 11 volts on start up which still leads me to believe that the FICM just isn't getting enough power. Is that possible or is it definitely my FICM?

Low Voltage to you ficm can result in ficm failure. I've experienced this twice now, once for batteries and once for alternator.

Well your alternator does not engage the second you start your truck. It takes an average of 15-20 seconds on my truck for the PCM to command the alternator to start charging

Your ficm has failed. At 30 volts she's done. It needs to be repaired. As far as the ficm tuner goes. It plugs into the obd2 port and tunes the ficm. It is not on the fly adjustable.
