Hey just for fun, next time you go out to do a cold start, pull the secondary filter and see if there is fuel in the filter housing.

Just for fun? Lol...what would that mean if there wasnt any in it? I run motorcraft filters every 10k. Also have done blue spring upgrade. I have no idea why its doing this...the truck runs perfectly once started...starts fine hot....starts up in 14 degrees without a bunch of fanfare....pretty stumped really. It didnt do this before the new FICM....could programming cause this? Or should I say, lack of programming

Thanks for sharing the existence of this thread, Bismic!
Software on the FICM will not cause an elongated crank, no.
I'd be curious to see your fuel pressure during the elongated cranking times, but would of course be most interested in seeing what your injection control pressure and IPR duty cycle numbers are during this time as well.
When you say longer cranks, what are we talking about? 15 seconds? 5 seconds?
Regardless, if you had a local buddy with a 6.0, you could always pop the FICM we sent you into it to determine whether the same issue existed or could, for that matter, send it back on in for us to look at. A Powerstroke FICM will start and run any other Powerstroke.
Hope this helps!

Icp during crank goes up faster than torque pro can keep up with so thats a mystery.
One puff of black smoke at startup then just a light haze on cold start..definitely fuel haze...no oil
Ipr duty cycle is 38% from the best i can tell...like i said...it changes faster than torque can keep up with.
When i say long crank...15 seconds or more
The craziest part as of yesterday....three days in a row now....cranks right up within 3 seconds! Been in the low 20s. No rattle on startup, no black smoke, nice smooth idle within a couple of seconds. Its the most baffling issue i have ever seen. I,was ready to pull valve covers and do stand pipes and dummy plugs...but im holding off now. Everything i have read and researched points to that....but at the same time, it does start hot and cold (although long crank when cold )

Have you posted any readings during a 20 second crank when it had not started yet? From what I can tell (and there are some things that seem contradictory), the readings that you have posted (the torque pro screen shots) are all after starting.
From your post above, are you saying that it still has an issue w/ a cold start or for the last 3 days you have had no issues?
When the IPR was 38%, what was the ICP doing? When you say the IPR was changing so fast, was it bouncing around (up and down)?
Update...fuel in bowl after sitting overnight.

The readings change quickly because it has bluetooth lag and the readings change faster than bt can relay. Same happens with IPR. Not bouncing around but quick climb.
The screen shots are immediately after startup and then after full warmup. I can try another screen shot during cranking...but with the way its been starting the past three days, i may not even have time to push the button!

The IPR Duty Cycle at 38% and ICP going up so fast that TorquePro can't keep up with it - is that when you are experiencing the long crank or what you witnessed when it started right up as it has been doing for the last three days? I'm guessing these numbers are from the last three days, but just guessing (which is why I'm asking )

Interesting. Did you happen to check if you had crank sync, cam sync, and/or FICM sync during these long cranks?
