My New 2019

[Wiredawg]

I hate drawing Ford-Ram parallels but I think the EPA regs keep them on par. Anyhow, I know beyond a certain soot level, you can initiate a regen through the steering wheel buttons and dash menu. With Ford, man regen is an option on the 550.

Wayne,

Thanks, I'll check.

Cheers, Ron

 

[gsbrockman]

How do you initiate a manual regen... I haven't found that on my 2017.

Thanks, Ron

I don’t think it became available until the 2019 MY. I recall seeing the charge on a window sticker earlier this year.

I wish I could find a definitive explanation of the regen strategy. It went into regen again tonight with the gauge on zero. I have been driving with the DPF gauge up, and caught it again. I had just done about a 60 mile round trip to visit a friend in the hospital, that was mostly 65+ mph, got home, and picked up mama to go for supper. When we left the restaurant it went into regen.

Obviously it has to be based on more than soot load. Is it miles, key cycles, daily horoscope, the tides, Punxatawney Phil???

So almost 60K on my 2015 and I think once after the fact I figured it had been in re-gen. So I just do not worry much about it. SnoKing

Tom,

My theory is FCA modified regen programming to proactively reduce/prevent DPF loading. This is my general observation on my 2017 5500, which regen programming appears is way different than my 09 4500.

This just may be one of the mysteries of the universe... and as long as no problems, good.

Keep posting, experiences are interesting.

Cheers, Ron

I've found that sustained highway driving, even empty, is mostly sufficient for passive regen. The dpf needs to see ~ 600° to oxidize soot on it's own. But from watching the soot load on my scan guage it only maintains during passive regen. It won't clear the dpf out per se at those temps. So you may have just been close to needing a regen when you stopped for dinner.

The "dpf 0" display is interesting. I've never seen my soot load % that low.

In 2008 Dodge came out with a update due to grocery getters having issues and turbo's sooting up. In 2009 I was getting service performed when the tech (the best tech there) performed the latest flash for the C&C. I never noticed regen prior to that, but afterward it would go into regen seems like every tank full. Fast forward to 2017, I installed EFILive, and running performance mode it would inrease the frequency. My opinion, and is only an opinion, they changed from soot level only, to miles driven connected into the overhead "Lie-O-Meter" using an algorithm. However after today, my C&C will probably go to auction, in my trade with my 2019 Laramie purchase.

After that reflash in 2009, the truck had a weird glitch that caused the RPM's to stick and the power turned up, after 2000 RPM, when in regen. When I felt the lag in performance, I knew to keep RPM's under 2000. Because of the manual transmission, it was hard to determine when in regen when loaded at the GCWR, and it went into regen on a 5% grade, and I hit that 2000 RPM threshold under full throttle, it took out my clutch. I will not miss that at all, in fact any hiccup with this new 2019, I will be the customer from hell until its fixed. It was my fault that I didn't force a resolution to the glitch in the C&C. Once the warranty was up, they couldn't careless, mainly because the Dealership was sold during the resession and the service went south. Prior to that, I could get free reflashes in the hopes that it would reset whatever had caused that. Once the ownership changed hands, it was like "Who are you to ask for free updates".

The same has happened to my 19, 0% on the gage, yet did a regen that lasted 19 miles on the highway while towing 7klbs

Sounds like a worthless gauge.

I know the gauge will register, as it did read a bar or two when I took delivery, which I chalked up to idling and putting around during transport, PDI, etc. Other than a brief cooldown, I avoid idling like the plague, and have been careful to mix in more highway by taking the truck sometimes where we would have taken the wife's miserly Acura.

I'm not saying it's broken, it's just sorta odd the way it operates. It does kill the MPG when it does a regen, though.

I HAVE TO assume that all these DPF/SCR Diesels all operate Regents similarly. I know Mack/Volvo and Ford do, and I been yakking it up with a new guy on my job, who was a career MB tech, and there’s a lot of similarities there too, so I have to assume these Rams are inline (pun intended).
I’d love to just shoot pictures and share what I learned in Mack emission school, I can’t but I’ll try n lay it out here.
There are 4 different regen modes in the latest DPF/SCR systems.
-Active regen. When extra fuel is used to make the DPF light off.
-Passive regen. When no extra fuel is needed for a regen, because the conditions are right for a light off (heat, oxygen etc)
-Sulfur regen. When the ECU thinks that the SCR cat has excessive buildup. The SCR cat is prone to storing sulfur, and needs to be cleared via by doing a active regen for a very long cycle, maybe 30 minutes.
-Crystal regen. As discussed around here, DEF can cause crystallization on the SCR cat and injector, etc. another special cycle depending on drive cycle, will call for this regen, and can last up to an hour. This cycle is supposed to cook off this crystal buildup.

If I owned one of these trucks, I’d surely have whatever scan gauge, code reader, Alfa whatever thing to read
Regen status
DPF delta pressure
The various EGT sensors
DEF injector status
DEF quality
And whatever else PID I could grab pertaining to the system.
Tom, our Ford 6.7’s putt around too much, and take ALOT to get anywhere near a soot warning.
Don’t worry and use the truck! Get something that can read the deltaP, and you can watch that as the ultimate soot load gauge.
You know you’ve done a good cleanout when you can see it the the mirror!

Why drive yourself crazy.....looking for a watched pot to boil? These trucks are basically seamless and very transparent in regards to regens.

Through 362k miles on my 2014 3500 and 155k miles on my 2018 4500........I have never really felt the real “need to know” in regards to regens.

That is what I said in almost 60K in 4 years, once after the fact I thought it was in regen. I just drive it. Was down to a half a tank of DEF today and we leave in a few weeks for Az. So I poured a box of Peak Blue DEF in it at WM and let them recycle the box. Date code was 20131 and there are 121 days left in the year. So it was manufactured 10 days ago, and has a WM label the read 8/25. The Supertech DEF jugs had white crystal all over them. 4 or 5 bucks cheaper for it, external crystals included. My truck has only had Peak Blue DEF in 4 years.

Because I'm a neeerrrrddddd and have nothing better to do

Yea. I know. And I was the guy who had a vacuum gauge on my dash back when. And of all my friends and “car experts” nobody else knew what it was telling the person looking at it.

My scan gauge has the ability to look at virtually every function of the after treatment system. My 14 however does not seem to care about nearly all of it. There are PIDs for DEF quality, DEF dosage, temp, etc.
And then there is DPF state which includes DENOX, mission regen, DESOX, H2O DESORB, HC DESORB, non mission regen, and make and maintain heat. I don't know if the recall wiped out the ability to read some of this or early gen scr just didn't care. It would be interesting to see someone with a 19 run the PIDs from a ScanGauge

It seems that someone with real knowledge (Sag2?) recently said that there is also a time period for regens as well, that regardless of DPF load, it will regen every X amount of hours.

That is another function the scan gauge can (supposedly) track, hours between active regens. And another function my 14 does not care about nor monitor. Big ol goose egg.
