My edge Insight CTS3 has been dependable on my 2022 F250 XLT 6.7 and seems even better with the updates for my 2024 F250 XLT 6.7.
I've got (for now) the PID's dialed in. Specifically, for the EGT values. I can see when the EGT1 goes from 400F to over 800F a regen is occurring, EGT4 does the same but last time it peaked at 1050F. Highway driving on a curvy canyon road (Hwy 199 in Calif). I do monitor DPF load and DPF pressure so that KIND of tells me when a regen might occur, but can I use the PF regen? The value has risen in 180 miles from 35 to 45.
Looked thru PID's and found the one PF-regen-. Is this the percent gone until the next regen?
Secondly: is there a table or list of what the PID's are in normal everyday terminology?

Don't need a pid, use the odometer. Unless towing, which changes everything and relies on Soot level, its will do a mandatory regen every 496 miles. So take the current reading and divide it by 50X, replace the X with how many miles you average on each regen, and that will give you a ballpark to start with. Then if you can catch when the next regen happens, add 496 to it to know when the next one will happen. For the towing, I don't know the PID, but you can look for stlvl% and use that. The mandatory regen doesn't rely on soot level and can happen anywhere from 28-36%.
All understood but with the variation fuel quality and driving conditions (Towing) could the Regen occur earlier?
Still wondering what the PID PF-Regen shows? Maybe I'll have to wait until it gets to 100 or a regen occurs.
Richard?

I have a 6.7 Ford HO in a 2025. I have a Banks I-Dash and it tells the percent to regent. When It hits 100%, it will tell you active regen has started and will start lowering that percentage after 5-10 minutes. Not sure what year they started the 9th injector in the exhaust DPF. When regen starts it doesn't change EGT1 as fuel is sent to the injector in the beginning of DPF. Sensors EGT4 and EGT5 come up to 1000 degrees or more during the process. IMO I really like the Banks I-Dash. You can customize 5 different pages with up to 8 settings/page, set alarms for many different parameters, see codes, clear codes.

If I'm understanding correctly, When a partial occurs EGT1 will go from approx.400F to over 800F and EGT4 will possibly go over 600F (hotter gasses entering)
If a full occurs Then EGT1 will go near 800F and EEGT4 will go near or over 1000F.
I do watch both the EGT's and DPF parameters. I've got 15 values I want on the screen and if I understand adding PF_ Regen it will fill the screen with useful info.
I will track mileage until next regen, will that be a full or partial?

My edge cts monitor will track lots of things regarding regens with guessing using egt or dpf load percentages.
My truck regems 100% without fail at 497 miles since last completed regen. And it’ll have a regen status light telling you if a regen is active. And the dpf mileage tracker will indicate when ones coming up. It’s all on the bottom row in the picture…

I guess I don't know about a partial regen. There are times when I see the DPF percent go down a few percents but not what I would call a partial regen. Some say if your pulling hard the engine will generate enough heat to do a passive regen, but I have not seen this. I pull a 34' camper and boat combination which does pull moderately hard depending on wind and I have never seen my DPF filter reading go down much. If anything I think pulling makes it do full DPF regenerations more often than running empty. I only have 4500 miles on the pickup so far, so take my opinion with a grain of salt. My regens pulling seem to be around 350 -400 miles apart range. Some comments about EGT1 raising during regens, I'll have to watch next time.
Your truck has An Active Regen ( where it Actively inject extra fuel into the DPF) or it has a Passive Regen where it uses waste heat from the EGTs to passively burn off soot. Anytime your EGTs in the DPF are over 572°, your DPF is burning off soot. The 23+ newer trucks run about 150° hotter than previous generation 6.7L engines. So it's common for the Passive Regen to keep the DPF clean. I drove 200 miles Thursday with my 13,000lbs GN horse trailer and 200 miles home last night and my DPF stayed at 0% for almost the whole trip, because my EGTs while towing were 900-1100°. More than hot enough to burn off soot.
Now my truck will still do an Active Regen every 497 miles, But since the soot % is 0% to start, The active regen takes only a couple of minutes and only burns off small amount of extra fuel. The bulk of the regen process is being done with Passive regen.
What kind of gauge do you run? I wonder if something is not right in my 2025 6.7 Ho? One thing I noticed is the Ford DPF filter gauge is way off compared to the Banks. It will say zero when the Banks is 50%. The Banks will say 100% and the pickup kicks into Regen when the ford gauge says 50%
DPF SL and DPF Regen trigger and the dash does not always match.
My experience is that once DPF SL gets to 106%, an active regen will start.....if you interupt it by stopping at a red light for example...the new DPF percent will post and the regen will stop.
a stopped regen is bad as it allows layers of coked soot to build up and the build up will shorten the life of the DPF.....unless you do occasional static regens upon a few consecutive active regen interuptions.
there is a difference in bevaior of the 6.7 depending both on what flash your pcm has and if you have the ninth injector or not.
some folks report only 500 mile regens,....im suspecting some of those are due to clogged pressure sensors resulting in the pcm doing only the defualt 500 mile regen. not a good thing as the dpf life will shorten for reasons indicated above.
All 6.7 since 2011 have a built in Regen NOW at 496 miles. My 2019 did that, the 2012 might have done that, don't know was deleted when I got it, but knowing Ford, if they did something at the beginning they usually wont change it unless its negatively impacting. The major difference between 2011-2022 and 23+ is the move off the engine for fueling the regen. Prior to 2023 regen fuel was dumped on the exhaust stroke, starting in 23 they added an injector in front of the DPF to fuel the regen at the source. Its faster, and more efficient this way and less likely to get interrupted.
The trigger is either miles driven OR percent filled. If passive doesn't clean it during the 497 mile trip, then it will trigger a regen. If passive does keep it under 20% then it skips the next scheduled regen. If soot level reaches 100% prior to the scheduled event it will trigger a regen. Miles and STLVL% are your indicators. Also the dash shows estimated soot levels, not real actual numbers, sort of like how the DEF Gauge doesn't show actual level, only 1/4 increments. Why ford does this? damned if I know. Soot level has never gone over 34% on my 24 truck. I have not towed with it yet, so nothing to compare to outside of regularly scheduled events. I do see when its passively regenerating, the STLVL% will drop, but usually climbs back up quickly.
The 2023 6.7 CoffeeTable Manual has the following to say about Regeneration.
The section on Active Regeneration describes a Stage2 (or high temperature) regeneration, which adds fuel to the DPF injector, to clean the DPF, and adds fuel during the exhaust stroke, to burn sulfur in the SCR. I imagine a regular (Stage1?) regeneration under low engine load will not show elevated EGT, but a Stage2 will.
The CoffeeTable Manual doesn’t mention regens at 497miles regardless of soot levels, but my 2024 regens at 497 like clockwork. However, during my first 1000mile breakin period when I was driving very conservatively with no highway miles, the regens occurred before 497 miles. The soot gauge on the instrument console reached 101%. Since the breakin I haven’t seen an early regen and the instrument cluster gauge reads between 40 and 60% when a regen triggers. Presumably the value depends on how you drive.

I think i misunderstood the DPF Regen trigger %
The DPF Regen trigger % must just basically be the percent of miles driven/497 miles, unrelated to the actual restriction in the DPF?
I have had the DPF SL % parameter in the IDash screen and looked as if the engine goes into regen when the SL was only in the 20-30% range.
