Anyone know if there is a way with forscan to show if a regen is happening? Like a symbol or something. Makes no sense to me why ford would not have something show up on the instrument cluster.

 

you can enable the screen that shows you the
percentage in the filter for sure , no symbol that I know of . Ford didn’t want anyone to worry about it and just drive and it would take care of itself . However , I don’t like to interrupt regens so I use an edge monitor so I know when mine stops and starts

 

There sure is a way to know when in regen. Use the instant fuel economy screen. When your normal MPG is 15 MPG and you are suddenly doing 9 MPG, your in regen.

 

You would know in FORscan because the EGTs would start climbing with EGT1 first. I just watch EGT1 and EGT4 on my iDash. I'm lazy and need to figure out how to and set up a second page of 8 PIDS to monitor all four EGT PIDS at once. But watching the EGT temps would indicate an active regen because they start to get hot.

 

Yeah, it would have been real nice if they would have just had a little icon that would pop up when the truck is in regen... like mentioned above, watching the real time MPG is the best way, but catching it is another issue. I haven't noticed any higher RPM's, noise or even smell when my truck regens. Of course if you don't mind using Forscan, you can also do like mentioned bove and enable the DPF% screen. Another easy way would be to use a monitor like the Edge or the iDash.

And setting up a new page is easy with the iDash. Definitely do it! I monitor EGT 1 & 2, as well as the regen status on my page 1, but I have page 2 set up for regens.

 

Dude, it's like anything else... I drive my wife nuts with my procrastination powers!

 

Have you ever noticed the DPF Regen % not counting down while in Regen? Mine will sometimes not count down while the regen is in progress, but once the regen is completed the % number drops down.

 

So there are 2 different regen % status' in the iDash. DPF RG (as seen in my photo) and DPF SL. The DPF RG measures the DPF Regen Trigger while the DPF SL measures the DPF Soot Load Percent. I first chose the DPF SL when setting up my iDash, but I realized that the % did not match the DPF% that my truck showed at all. So I switched to DPF RG. I found that it more closely matched the DPF% that my truck reported, but still wasn't really all that close. Also, like you mentioned, the numbers would never drop... even when I was watching the numbers drop on the trucks display from a passive regen... in fact, the DPF RG on the iDash continued to climb until it hit 100% and then it just stayed there until I would complete an active regen. Even while doing an active regen the DPF RG on the iDash did not drop until the regen was complete and the number would suddenly change from 100% to (most often) somewhere in the low 20's. A couple of times it dropped to the high teens, but never to 0%.

Then recently I noticed my DPF% was not climbing on my truck... for about 165 miles it stayed at 0%... even though the truck wasn't climbing, the DPF RG on the iDash was... so I switched back to the DPF SL. It was very low... at one point it was at 2%. When it was around 7% the truck's DPF finally moved up to 5%. But now the truck is on 30% and IIRC the DPF SL is somewhere around 12%...

It's my opinion that the DPF RG simply counts mileage and gauges it by a percentage. From what I understand these trucks are set to auto regen at either 500 miles, or when the DPF% reaches full, whichever one comes first. I believe that the DPF RG is simply calculating mileage, and for this reason, it will not drop, even if a passive regen occurs. The only time it will change is when an active regen is completed. I am still curious as to why the % never drops to 100% though... the only thing I can think of is maybe it starts over immediately when the regen begins, and by the time it ends, it can't be at 0... however, I would still think that it would be less than even 20% as it only takes me about 15-20 miles to complete a regen.... I dunno, but I don't think the DPF RG is measuring actual soot levels, but instead mileage...

As for the DPF SL, I do think it is measuring soot loads/levels, however, as I understand it, when the truck shows the DPF% is 100%, that this is not really full... I have heard that the DPF% can actually each 200% before it is truly full, and I have even saw where some says it can go to 300%... either way, it sounds like 100% is not completely full, but is when the truck needs to go ahead and complete a regen... probably for health levels it is programmed to regen quite a bit before it is actually full. So maybe the iDash is reading a true soot load %, which would mean that it would not match what the truck displayed... Since I switched from the DPF SL to the DPF RG I never really paid attention to if it drops when going through a passive regen... So I am going to leave the DPF SL on the iDash for a while and watch it. I have a long tow coming up next week so it will be interesting to see how it reacts...

 

Had a active regen on the way home today after work.


During active regen, EGT1 will get hot first.



When both EGT 1 and 4 are hot during the active regen.


After regen EGT4 stays hot for awhile.

I gotta do a second display page so I can see what EGT2 and EGT3 do during an active regen.

 

Thank you for the great explanation. I've been using the DPF RG since purchasing the iDash. It does count down sometimes during an active regen, and sometimes it doesn't. The truck just had an active regen yesterday and didn't count down. I talked to Banks Tech Support, and they didn't have an answer for me (about 3 months ago), and said to call back if it continues to happen. I'll try them again. I had an Edge CTS2 on my 2019 F350 and didn't have this issue, but unfortunately it wasn't compatible with the 2022.

 

Circling back on this one, I have iDash now and set up the regen on/off active pid, and DPF SL% as well as the trucks DPF percentage.

What I find is that soot level reaches ~ 60% when DPF level reaches 95%. Once regen starts, DPF level drops quickly but soot level does not. When truck gauge reaches 0%, REGEN remains active because it is still bringing soot level down, which was ~ 12%. Regen turned off when SL reached 6%. So far monitoring one EGT, soot level, regen status works for me, the other spaces are RPM, speed, which is 1 MPH lower than GPS and 2 lower than speedo, and def level percentage. I also have two others regarding dpf, but not sure what they are as I have not spent a lot of time with it.

 

Maybe you're 19 is more accurate when it comes to the iDash SL% and the truck SL % but mine is not. I assume by DPF level, you mean the truck gauge?

If so then, yeah, my iDash starts dropping like crazy before the truck dash comes off of FULL and goes to 95%. But like I said, the iDash and truck are way different and track different. I've seen the iDash as high as low 140s.

 

There was another screen I had that mirrored the dash percentage, but didn't feel like wasting a slot for that, then found the DPFSL% It reads higher at 19 right now, and dash 0% still. They may be two different sensors.

 

You mean PID? Can you do me a favor and post up what it is if you don't mind? But you have a 19 and mine's a 16. Not sure mine would have it... thanks.

 

My 2015 had a Cleaning Exhaust Filter msg pop up when it went into regen. My 2018 doesn’t and when I asked my service guy why he said “I think it’s because ppl would freak when the cleaning msg would come up within a few miles of parking and the fear that something would happen if the driver wouldn’t pass home and go for a long drive”. He said he had quite a few express this concern, he doesn’t know if that’s Fords reason or not. Sounds not unreasonable. In ‘17 or ‘18 Ford stopped the msg showing and now no one worries about the regen anymore. Or that’s the logic.
