Automatic Regen too often

[AH64ID]

@mbarber84 the lack of a decimal point on the Banks iDash means that it’s rounding up and 100% will show at less than 100%, this happened on my CTS3 until I added a decimal point. Now as it hits 100.0% it goes into regen.

You made it to ~24 hours, but barely. Bouncing around means the PID is being driving by soot loading. 93% is 22:19, so how long did it take from that 93% reading to go into regen?

The data you saw at initial active regen does indicate time based.

16% after being shut down for 2 hours tells me you either didn’t get a great active regen, or you have a lot of ash buildup in the DPF, or …. Software/sensor issues. You do have more miles than me, but I often see single digits after the first shutdown.

The truck was showing 91% when I left the house this morning. I’ve been on the road sporadically all day. The PID did eventually settle down to about 93% at roughly 2-2:30PM but I don’t recall the mileage at that time. Engine hours would’ve been about 1,332 if I had to guess.

As far as the regeneration itself, I would assume it got a fairly good regeneration because it was all highway at 75-77mph. I saw about 1,050°F or so for at least half the cycle. I would certainly hope there’s very little ash buildup at 46k miles, using a low ash CK-4 100% synthetic Amsoil signature 10w30

Random question that might be able to be answered. I have a Bluetooth OBD3 with PIDs from my ecodiesel. I used it to monitor boost, egts, active regens and passive regens (and more) from my ecodiesel. I'm curious if the PIDs would be the same. It was handy because I had it connected to an old android with the torque pro app. I have attached a screen shot of my main screen within torque pro.

I'm still without my truck. Itll be 10 weeks on Friday

When I got rid of my Ecodiesel I moved my Scangauge II into my 2019 2500 6.7 and had to change the PID's. Scangauge has a list of PID's for 2013-2023 Ram 6.7 here.

I also obtained a couple that weren't listed on their list.

Update:
Had my last regen today 971 miles and 24 hours since the last one. DPF gauge had gotten up to about 3/16 before heading out but quickly dropped back to zero and about 30 minutes later went to Active Regen. Lasted 20 miles and 18 minutes. I believe the Archoil helped to make go this long. The one before this one was at 11 hours and 396 miles.

Was this a combination of 6400d followed by 6500?

yes it was. I put the 6400 in and 40 miles afterwards it regened. I ran that tank down until the low fuel light came on. I had mixed 3 oz of 6500 with 30 gallons of fuel in my auxiliary tank and filled it back up. I ran it down until I could empty my auxiliary tank and mixed up another batch.

 

[OLEJOE]

When running the 6400d and the 6500d, I noticed the truck still made soot when the rpm was down and I hit the throttle hard. It was like it injected too much fuel for the turbo speed or the amount of boost that it had at the moment. I’ve had it happen previously also. I had gotten off of the interstate and was getting back on. I had the cruise set on 75 and was probably doing about 60 on the ramp when I hit resume on the cruise. The transmission did not downshift from 6th gear and the DPF gauge went immediately to 1/4 from zero. Maybe someone knows what is supposed to regulate fuel delivery according to boost/rpm ?

 

[mbarber84]

Going from 1/4 to 0 is not making soot, it’s an indications that soot has been cleaned out.

1/4 to 0 is a big change. I’ve not ever seen mine move more than one segment at a time, with 1/4 being two segments.

That being said, 1/4 to 0 under those conditions is part of the reason I believe it’s a programming error. You put the airflow in an accurate part of the map and the gauge responded accordingly.

I think he’s saying the soot load increased (not decreased) from 0% to 25% in a rapid instant.

I read it 3 or 4 times, but yes you’re correct. Long day…

Usually that scenario, increased airflow, is when mine drops quickly

No worries just wanted to clarify.
I completely understand!

Here's some interesting data. 19 2500 6.7 with 64k miles. Regens every 20 miles intown or 100 miles on the highway. DPF filter will go from 0grams of soot to 2grams then to 6grams of soot over the coarse of 5miles doing 75mph on the highway.

Today I forced a regen with alfaobd. First regen dropped the truck from 6 grams of soot at 50% full on the dash to 4grams of soot. After 35mins. Second forced regen dropped it to 2 grams of soot. Turned off the truck and restarted letting it idle for 2 mins then bumped back up to 3grams of soot immediately on the gauge.

Currently waiting 2 more weeks to get the truck into the dealer. So far I've pulled the maf sensor and cleaned the carbon off and going to throw a factory mopar intake and filter back on this week from a buddy to see if that helps. Currently running an afe.

Did you clean the MAP? The MAF is right after the airbox.

Sounds eerily similar to my '22 that I've now rolled into the 3rd month (week 10) of it being in the shop with no end in sight. They replaced the MAF and it did nothing. Same with air filter, CCV, oil change...

Yes I cleaned the map also. Swapped a mopar intake and AB filter from a 21 6.7 that has no problems to try today. I swapped all sensors from the 2021 truck on the intake. Will report back. Next step is to swap the maf then dpf pressure sensors and hoses. Trying to get this solved before going to the dealer. Trucks under warranty but I'd rather not wait

After changing out the intake system and the sensors, it may take a little while for the ECM to adjust to the new parameters.

Keep us posted. I feel like with mine they're blindfolded throwing darts at the wall. With that said, RamCares has initiated/floated the idea of a buyback. I haven't got that far though as I paid cash for the truck and I'm not looking to take a proverbial bath on the buyback to have to then even have a small loan on a new truck. Admittedly I have no clue how a buyback works. I looked up KBB trade in at $70k or private party at $73k.

Went for a 25mile ride tonight. Roughly an hour of non stop running. 15 miles on the highway at 75-80mph then 10 miles of in town driving to finish it off. The truck was left running while shopping. Below is two separate data collections. One with the afe intake with 2019 sensors and the other with a 2021 intake and sensors. The factory mopar intake from the 2021 had a dirty AB mopar air filter in it. As you can see my soot stayed at 4Grams the whole trip. What was interesting was the mass air flow and mass air frequency between the 2 intakes and sensors.

I'm going to run the mopar for another day then throw the afe back on with the 2021 sensors and see what changes. I called afe and have a ticket in with there engineering staff to speak about this issue. Also grabbing an mopar intake to have Monday off marketplace to use since I'm borrowing a buddies.

The last 3 weeks or so my soot level has been zero constantly and as far as I can tell it hasn’t done a regen . I have gone on 3 trips of approx. 300 miles each with the 5th wheel. I use tow haul mode and full exhaust brake and use the gear limiter to 5th gear.
Our travel without the 5th wheel was minimum. It’s all most like I have the opposite symptoms as most of you on this thread.
I get no warnings or blinking lights etc. and the truck seems to run great. So is this too good to be true , do you think somethings wrong.

No I don’t think you have any problem. Your truck is doing passive regens when you are towing. When it hits the 24 hour mark since your last active Regen, it will regen again and that is operating normally.
If mine starts building soot from easing around or short trips, I can hook up to my TT and within 30 miles it will be back to zero.

Well my truck went in again for frequent Regens. The dealership had to change the oild under warranty last go around thanks to injectors leaking diesel into the oil. That said, I am now being asked about my fuel filter replacement, as though I don't keep logs or it is somehow my fault.

I am incredibly frustrated as to how the conversation always comes back to me, and how they can't disprove my maintenance is the problem. I only use mopar filters and never get anywhere near the mileage listed in the manual.

Side note....I didn't want to touch the oil that they put in, but per the dipstick, the truck is likely still making oil.

I in good conscious cannot sell this truck or trade it in for them to sell, so I don't know what to do. This may be the perfect candidate for the Alaskan 4th of July car cliff launch.
