I strongly encourage those interested in this subject to download the appropriate Coffee table book to learn. There is a 6.7 Powerstroke coffee table book from 2011 and Updated 2020 and a updated 2023 coffee table book that explains how the regen works

Thats for trucks up to the end of MY22. 23+ use a different strategy since it injects fuel directly into the DPF, no longer using the exhaust stroke for the fuel source. There must be some reason for the 500 mile regen window. I had it happen last night on the way home. Again, it did not trigger the iDash that it was in regen, I found out when I looked at my trip economy and saw it dropped, then glanced at the iDash and saw the EGT were running 1100*. DPF never goes much past 30%.
Unlike my 2019 that took 30 miles to complete and NEVER went below 4%, this one takes it's time to build up, and does not regen at exactly 497 miles, but over time I noticed the distance grows. Probably more of the adaptive learning.
Edit: Upon looking to see if there is any information on the 23+ cycle, I discovered the quick and easy way to find places for deletes, Just put 2023 6.7 dpf in the browser. All kinds of places selling delete kits and tuners, but not ONE example of what the 2023 6.7 DPF does or looks like.

The exhaust stroke is when the engine pushes raw fuel into the cylinder on the exhaust stroke and it is pushed downstream with the exhaust. ( It is how the 2011-2022 trucks do it before the 9th injector was added)
It is still needed, Not for an Active Regen of the DPF but to do a Level 2 Regen which is the process of cleaning the DOC/SCR Both section of the emission system are UPSTREAM of the 9th injector.

Stop, get out and take a deep breath. You will instantly know! You would need a scanner connected to the OBD port, like an iDash or ECT(?) and set up a few pids for the EGT's and DPFST$%.

Auto Regen
Well, I guess i just when through an auto regen on my truck and turned it off while it was in the middle of the operation. It smelled like burning rubber to me when i walked by the truck. I thought it was not good for the truck if I turned it off during a regen. How do I avoid it in the future?

Did Ford tell you not to turn off the truck during a regen, or was it a guy on the internet? What's the "manual" say?
If it was not good to do, would Ford disable the ability to turn off the truck, place an alert on the dash, or mitigate it in some way?

Auto regen
No the dealer did not tell me anything, surprise surprise. No, the manual says nothing about detecting an auto regen event or what to do while it is happening. I looked in the manual before I ask the question. Again no surprise about manual saying nothing. I hoped it would just be a simple question with a maybe simple answer. Thanks.

I did this on my diesel truck last week and have done it before with no ill effects. It will just redo the regeneration on next run.
Only way to detect a passive or active regeneration is by using a scan tool/monitor. I recommend a Banks iDash with a pillar mount. Or you could do a less obtrusive method and do a Bluetooth OBDII reader with a scan tool app on your phone. I use BlueDriver and while I don't have it running all the time, I periodically check to see when it will go into the active regeneration to keep an eye on things.
The only other thing it does is waste more fuel by you cutting it off. So if you can, keep driving it till it's done.
To clarify:
Active Regeneration = Dumping fuel into the DPF to do a full burn off. Could get activated by soot percentages or by drive time/miles.
Passive Regeneration = Burning off the soot by driving. Heavier loads/highway use will burn off the soot quicker. Does not dump extra fuel into the DPF canister.
Personally, you don't need to worry about it unless you drive like grandpa or do a truckload of city/slow driving. Or the worst, a lot of idling. These trucks like to be run with some skinny pedal action.

Make yourself a cheat sheet. Number 1 through oh, say 20, and multiply 497 per each line. Keep it posted where you can see it on the dash, and at each line compare to your odometer. You should be regenerating within a 10 mile range of each line. While the truck shows 497 on mine, I found it varies by as much as 20 miles between regens. The point though is a regen happens within every single one of these lines you wrote. For example, 20 regens is right around 9940 miles on the odometer. If you are not towing in the first 10K miles from 0 where you start the note, then you will have a regen right around 9950 miles. Sure enough, 9954 miles, a regen started on mine. Of course if you tow it can adjust the regen period if a full regen occurred between clocked time.
As for keep driving, not a smartass remark, if its doing a regen, keep driving until its done. You just have to know it is in regen.
