My edge CTS tuner says DPF load 145% when it starts to regen correct. I was also told by a Ford mechanic that it really means 47% though. It’s like 100% off. 200% means it’s 100% full. I know why in the world would it be like that? I’m as confused as you are.
I am going over to a buddies who is a Ford mechanic and he is going to reset everything tonight and check the CAC tubing. Something is wonky and I will report as soon as I know. I have been dealing with this for a year with no solid answers. I do a lot of out of state hunting and there hasn’t been a time where I haven’t had issues.

Weird way of measuring, but, ok I guess.
I never did understand the concept of giving more than 100% since I consider 100% being the most anything can give. So if it gives 110%, does that mean all the rest of the time is was really giving only 90%? It's not like it was resized, like putting larger intake pipes on that increase airflow to 120% of factory, that means the new pipes add an additional 20% of air.
But that's just how my mind works and what Edge said just confused me more.

I quite monitoring soot load or DPF RG.
With auto regen un-checked and the soot load screen enabled on the truck I just use that.
When I get the prompt to clean exhaust filter soon then I do the regen if convenient.

We know 100% or rather "FULL" on these trucks is NOT a true 100% full. I'm thinking the software from these companies for monitoring SL % is not exact or maybe more sensitive to changes in the pressures in the DPF... I don't know. Just thinking out loud is all. It's not like Ford would hand over their calculations, data tables and software to Banks and Edge.

If you watch DPF soot load using the Ford's IDS it will indeed go above 100%. What your seeing in the Edge isnt a calculation the monitor is doing, it is pulling that data right from the PCM. 100% load in the DPF just means the DPF has what Ford considers to be it's max ideal operating load. Above 100% is where the PCM starts to watch for the correct conditions to run the regen cycle. That does not mean the DPF is actually full. If you try and run a static manual regen using the IDS for anything under 100% DPF load it will even tell you regen is not recommended. I have seen quiet a few, more so in Transit vans with the 3.2, that come in with DPF issues and are loaded, accoring to pid data using the IDS, to 250% or more. By that time the engine will barely run as it cannot breath.

Another ?
my 2015 makes a whine noise at idle when up to temp. Drives me absolutely insane. I have read a ton about it. People have gone as far as replacing engines and transmissions to solve this problem from what I have read. But no one has seem to really pin point it. The whine goes away after oil change for a bit then it will come back.
I think it’s the movement or hydraulics of the engine oil in the pan. Just a guess. Has anyone ever cracked this nut?

Now that makes more sense. The PCM uses a percentage based on 100%/2. True 100% would be 200% calculated, which would mean an almost plugged DPF, clean now or die situation. A full regen now would trigger ~80% actual capacity based on that input. That also explains the 20% variance between iDash and dash readouts.

Mine hit full yesterday, iDash 80%. I plan to refuel either today or tomorrow, not going anywhere today, and didn't regen since it was too close to home. After I fuel up I will trigger it and drive a while until it completes. Last time I did a regen though it stopped at 15% and not 0%, which was kind of odd.
