I have a '22 so no bells and whistles going off or the option for manual regen (that I know of). In 40K miles of driving I have never been aware of it completing a regen cycle...... I must be ignorant to what to watch for but I've never experience a high idle or excessive drop in fuel consumption...... What am I missing (other than the obvious regen cycle).... ?

 

On my 22, if it weren't for the iDash showing me the regen status, or the fact that I use OCR to turn auto regens on/off to manage them, I wouldn't be able to tell that I was in a regen. To me, the truck doesn't sound any different, smell any different and operate any different when in a regen. Aside from OCR, none of them have any sort of bells or whistles telling you that a regen is active. The only way that you could come close to being able to tell is to look at the instant mpg readout... but then that could also depend on situation. It does seem like Ford made sure that it was just something that occurs in the background without any necessary user interface whatsoever. At least not until it is....

But, the reason I do keep up with mine is because previously, I did mostly short drives. So, I didn't want a perpetual regen that tried to start up everytime I cranked the truck, but never actually finished. I didn't want that for fuel mileage, but more importantly for the health of my DPF, and of course the truck. So, I wanted to see when it was time to complete a regen, plan too be able to drive the truck until it was completed, then turn it back off. This meant no partial, or interrupted regens.

Besides this, I don't want to unknowingly shut the truck off in the middle of a regen when my EGT's can be as high as 1250F. I always prefer to wait until EGT1 is 400 or less to turn the truck off, whether after a regen, or when just out for a drive. Makes me feel better.

 

I drive a 2022 Power Stroke as well. I had my dealer enable the auto regen, so that it can be switched on and off. And at the same time turn on the percentage screen, so I can see what the soot load is. I turn off the auto regen feature, when the load reaches 100%, I get a message on my dash to clean filter. I turn the regen on, and watch the percent screen run to zero, switch the auto regen off, and wait until I get the dash message again...........usually between 550, and 650 miles, but on the interstate I have gone 800+ before I got the message.

 

I'm going to assume Ford wants it that way....no reason to know when/if its happening. Just enjoy the truck is the assumption. I have the Banks iDash to monitor just this and I think its useless. If I'm in a regen and pull in to park the truck, regen automatically turns off as I put the trans in park. Sure the temps are still high...but if I didn't have the gauge to show it, I wouldn't have a clue. If the truck is used as intended (work) then regens will happen completely. I tow heavy with my truck on long inclines, 92k miles and no issues.

 

I use mine like a truck as well so maybe I'm overthinking.....thanks guys.

 

Without auto regen turned off, it will be doing a regen at 500 mile intervals at most. I used forscan to enable manual regen and the DPF % display. If towing, I can go indefinitely without a regen.

 

I tow and only go ~500 miles and my dash alerts me that a Regen is about to take place. Usually lasts ~20 minutes at highway speeds.

 

The 20 plus trucks are nice that you can have the dealer turn the auto-regen feature on/off or do it with FORscan... that is a great option.

Having the iDash in my truck to not only monitor regen status (off or on) and monitor EGTs to make sure they are cool enough to shut the down after an active regen (just like being cautious about shutting the truck down too quickly when working it and the turbo is still hot), but it is nice to have a permanent code reader installed in it to read/clear codes and the option of performing a OCR regen with the iDash. I also like the more accurate fuel level PID and the primary fuel pressure from the DFCM (only the 11 to 16 6.7s) feeding the CP4. Being able to monitor the primary fuel pressure is necessary IMO because I run my factory fuel filters out to almost the factory CI of 22.5k miles, so I can watch that PID for subtle changes in fuel pressure (or not).

In my truck, the dash does flash the "CLEANING EXHAUST FILTER" message very briefly but it is easy to miss especially on the 65 MPH expressway I drive everyday. The iDash picks up the regen first before the truck displays the message... usually the truck shows the message about on mile down the road. When I am in a active regen, the times I have exited the expressway, I have heard the sound the engine makes when it's in regen and almost sounds like the engine brake is on with exhaust back pressure... but it has its own distinct sound. You could watch the truck MPG monitor and it will start reducing when in in regen mode. I have also picked up the smell duirng an active regen as well...

I agree on the partial regens as I have had that happen to me. It was unavoidable as I arrived at work... the key for me after arriving at my destination to allow the truck to idle which not only shuts the regen off (for me usually under 30 seconds but have read up to one minute) as it is possible to shut the truck right off in regen mode, if I did not know better, and have read that those injectors will stay under pressure dripping fuel (don't know if true) but also reading the EGTs, both EGT1 for turbo temp and EGT4 for DPF temp to allow them to cool down if need be. It is my opinion that I do not want to shut my truck off when the DPF temp is very hot as I want to avoid possible filter substrate damage, cracking that is, from the high temps as exhaust would no longer be flowing through it to cool it down. I like EGT1 to be 350 deg or less when I shut my truck off to keep the turbo cleaner from oil coking up.

I bought my truck because I wanted a diesel and certainly did not need one.. I want to drive this truck. I came here to learn what I could on the 6.7 and also looked into it online. Once I learned, I knew I had to monitor the parameters of the truck if I was to keep my truck trouble free with the emissions. I also realized that I got lucky by living south of Buffalo, NY and that these hills I climb get the truck hot, keep my emissions happy and reliable. I'll never rule out deleting my truck as I am aware of what is going on with the EPA but frankly speaking, I like not smelling the modern day ULSD fuel exhaust because IMO, it is irritating AF.

Ford should have went to the 9th injector in the DPF from the get go like the 23+ trucks. Regens completed in 5 to 6 miles... how freaking nice and convenient is that?? And less fuel in the oil for sure.

People ask me all the time, "When you buying a new truck, Dave?" And I tell them I'm not. I'm not spending more money, a lot more, on a truck I don't need and want to drive. I will though however, help my older son buy a new truck and teach him how to care for it. He would not do what I do with mine.. take it regen runs... I have put on 100 to 125 miles (including the drive to work and starting back towards home) many times, when taking it to complete a regen, but climbing the hills she gets hot and passively regens which stalls the truck from going hot. It it a PITA? Yes. But it is what it is... plus the fact I bought the truck the same year I lost my Dad. I am keeping mine and will "KEEP ON DRIVING," a quote from the show Roadworthy Rescues.

 

I must have a sensitive nose. I have always been able to tell when they are in regen by smell.

 

yeah, I can usually pick up the smell, but not always, when I'm on my "regen" expressway... but even getting off the throttle and slowing down, the engine has a unique sound when in regen when off the pedal...

 

I had the DPF percentage screen added by the dealer early on with my 2017.

I also have a ScanGuage II set to show when I am in a Regen.

If someone is monitoring their mpg, that will definitely head to sewer when in a regen.

 

I can hear it in certain situations, but I almost always smell it. On the highway it's usually just luck of thew draw if I happen to glance at the CTS3 and see that it's on. Used to have an alarm set for it, but never set it up again after going with the edge tuning.

 

I always plan to be traveling down the highway when doing mine, so I never smell anything or hear anything different.

 

I always plan a drive long enough to let it go through the process. I may give a go where I wait until the display in the cluster reaches 100% instead of enabling auto regen when the IDash displays 100%.

 

I have on my dash the factory enabled DPF SL % PID. I'll take it on a regen "run" normally. Recently I had two mileage triggered regens because the SL% was not at "FULL" on my dash. I must be doing something right for a daily driver with no weight and it getting triggered by mileage. The last one was at 496 or 498 and the one prior went over 500 miles... like 512 IIRC. I credit the altitude where I live, lots of hills on the expressway, and the additives I use...

But have had ones in the 300s (miles since last regen) but normally in the 400 mile range, at least. Depends on how much stop and go I do.

Once I get at 90% on the dash, I pay attention. Since mine is a keeper and I don't mind being stock, I like to monitor this stuff.
