Whats the advantages of a 58V ficm vs the 48?

yeehaw · Feb 5, 2013

only thing i really found different was that the truck started better/smoother in the cold

hmmm... well if that's it I really don't have to worry about that here in SC. I just have to get mine fixed since she was only reading at 38 volts. Thanks

if anything, i would order up a FICM tune then.

I was wondering the same thing.

Yeehaw - What advantage does a FICM tune offer? Is this something you do in addition to also having custom tuning done to the truck? Or is it a "one or the other" kind of thing?

Optimal to get both, custom ECM and FICM tunes.

Any recommendation on who to have do this or is it a ford program?

Total Diesel Performance can tune FICMs

I used Power Hungry Performance to FICM tune, which I did a ECM rollback at same time to gain some MPG, and I got Gearhead tunes but there others

Topgun the 48v you are running is tuned by KEM, my 58v has Php's atlas 40 on it and it compliments my 175's great. I know Idp also tunes ficms. I'd contact whoever you are gonna have do your sct tuning, or have php flash a tune onto your ECM once you figure those issues out. I think ficmrepair.com can do php ficm tunes too. Just don't overtune your ficm if you are upgrading injectors. Over 155cc I think some ficm tunes get hot.

think most people gearhead,innovative,kem,php all have a ficm tune. getting ready to start putting our flat bed together and going to get a ficm tune on it,there was a link somewhere with kem showing results. but it was only between swamps 58 vs stock and then kem vs 58v not others like php etc so it only showed how great kem was. not knocking them because the results were good but it didn't show competitors since they understandably conducted the test
