I dropped it off at the dealer yesterday, they will look at it today or tomorrow. The cleaning exhaust message came up and the idash said it was on, about 35 miles into the drive regen went off. I asked about the ghost screen too.
I'll have to look at my notes, organize them because I've got a stack of big post it notes that has to entered into one note pad or location... I like recording data but I'm not the most organized.... I've seen 28 miles and up regen intervals but I'm thinking maybe you aren't getting hot enough to have shorter intervals in mileage...
My regen today was 20 miles long, iDash was at 0.0% and truck at 25% when it shut off. After it shut off, I was on the expressway, EGT4 (the DPF) stayed hot enough and it passively regened to 20% before it dropped under 1K degrees, then it won't burn down anymore after that...
Another thing I'll add here, I use Pittsburgh Power's Max Mileage FBC which is a rebranded Better Diesel FBC. Pittsburgh Power offers a half gallon bottle. It's meant to lower the combustion temperature of soot and which, IMO, it has helped me because I have seen the truck passively regen down 5% if the temps are hot enough in the DPF... I wrote some notes so I'll find them and post up here. This happened twice in recent times.
On the other foot, if I'm driving the local roads here and not climbing any hills, SL does climb a lot quicker then when I'm driving into work and climbing that big hill on the way in as well as when I drive back home, the altitude climbs and it gets hot enough to either keep the SL constant or if it gets hot enough like I said, in the high 500s low 600s, she will passively reduce the SL and reduce at least on the iDash but if enough, will reduce on the truck SL% PID...
Just received the iDash and have a question; I have set up the screen to include what others above have as their main screen including Regen status, DPF SL%, ERG1, EGR2, EGT1-4. This past weekend I activated the OCR function via Forscan and the reading says the DPF filter is 75% full, while the iDash Soot % says 21. Are these two different values? Thanks!

I just think the iDash is more accurate or rather detects changes in smaller increments that the truck doesn't as the trucks reads in 5 percent increments.
We know that the DPF is not completely full when the truck reads FULL or else there would be problems... There's been comments here from guys that know more than I do... Maybe they'll see this and comment.. I think I've seen a high on the iDash of close to 150%... But yeah my truck and the iDash do not always stay in sync... Plus I'm an older gen and Ford may have changed the particulate percentage software some for the newer trucks... Who knows.
Ok so when in active regen today, just like when the SL is climbing, when the soot is reducing during an active regen, the iDash reduces a lot quicker than the truck. But at 80%, they are the same until about 70%. Then the iDash once again reduces quicker than the truck. I noticed that when the truck was at 60%, the iDash was at 40%... etc... then they were anywhere from 20 ish to 25 points off... so keep this in mind plus the newer truck may be different in this regard... mine's a 16...
Going to keep the DEF level % going and see what happens with it... if it's not accurate or I don't like it, I'll figure out another PID to place there and keep the regen background alert going...
Ah, thanks for the pic! So, the popup says "Regen" (to indicate the action is progressing, and not like the "On/Off" cycling with the static option). And, it keeps the existing PID that you had assigned in that first spot?
I think I'm going to do the same with mine, as that dedicated regen trigger is just a wasted spot that another PID can use. I'll have to see how many other background alerts there are, now... lol

No problem Joe... the box that pops up is bigger. Mine was blue with yellow letters I believe due to the colors I have set up for my EDC screen... to grab your attention. Then that small box that says regen just stays static... like in the pic. It does not cycle back and forth between ACT and ON like it did when the slot is assigned to the regen status PID.
So the last 4 drives the message did not come up or show up on the idash. It would display after 4 miles and show up on the idash. These are the same and 2 longer drives than I have done previously.
So I think it's not coincidence that your DEF level says 67% and mine's the same... mine was at 69, dropped to 68 and back again a few times... but now at 67%. I'm going to keep it displayed to see what happens as I think it will drop to under 50%... I'll see for sure... has yours dropped below 67%?
How do I do this? I enabled the soot load % on the dash today and it's reading 90%. On my Ram I never saw this because at 80% it would auto regen.
I'll look tomorrow as I've posted the procedure before here... But at 90%, realize the DPF is not 90 percent full. Someone here more knowledgeable than myself has said exactly how this works...
If the filter was 100% filled up at "FULL," the truck would have issues... Just know that when the dash goes "FULL," it will go active soon after...
Sorry for the delayed response, it was a busy and fun past few days. Got the truck back from the dealership, drove 225 miles, 50 of them below 10mph and lots of stop and starts.
At the 225 the SL was around 160 and the cleaning exhaust message came up. It went down to SL 53 when I had to shut it down for a stop, then for the next 60 or so miles the SL climbed back up, still under 80.
I did average 19.3 mpg up and back to Canada.

Sounds like the truck has the latest software and it's doing it's thing now... happy to hear you got it resolved... the SL will climb fairly quickly (or quicker than when temps >>for me<< are under 500 degrees and closer to 400 deg) #1 -- when EGT1 temps are cooler, so engine produces more soot (IMO) because I see it when I come down the big hill before my house and #2 when the DPF (EGT4) gets cooler -- when under 500 degrees. This is my experience seeing how I daily drive my truck unloaded...
It's great you made it home... keep us updated on what's going on with your truck... have a good night.
Whenever I start the truck egr1/1 is always at 392°, I talked to Banks and they suggested a soft restart on the idash which I will do after work today. The temp also goes up and down quite a bit too.
I'm on my second day off today... I'll switch to my regen screen and see where my truck is at but like Scott says, EGR is different from EGT. EGR1 is exhaust gas directly from the exhaust manifold and the EGT PIDs are in the exhaust with EGT1 right after the turbo... So EGR1 will be hotter because it's coming right off the engine.
