Automatic Regen too often

mbarber84 said:
Install was very simple and quick. Less than an hour total. Added one extra day to the process because I opted to paint the stealth pod to match my interior. Now it’s time to start logging data. I only wish I had this the past seven months when everything was running beautifully. View attachment 73412

The PID "DPFDIS" (average distance between regens) you are showing is 2 miles - how can that be - mine has been pretty accurate when I compare to my manual logging.

I’m assuming that’s because I just hooked it up to the truck and it’s probably not had time to generate an average yet? Not really sure.

Pretty sure the idash does not store any info - it pulls all data from the ECU so it should be current - I have had mine for over a year now and can't remember what it read on mine when I first installed them. Will be interesting to see what you learn from using yours on your regen issues (when not towing I regen more than you)

depends on the version you get. some versions have a micro sd card that saves the data
 
MBarber- been reading your forum stuff for a while. I have a 22 Ram 2500 Limited Mega with 6.7 SO and 68RFE. My truck has been regenerating every 20 miles, averaging 37 miles in regen for the last several months. No CEL, just my own documentation as well as oil creation creeping up the dipstick. Ramcares finally convinced a dealer in Norman OK to look at it. They've had it for a month, and are finally attempting new parts - starting with the MAF. I'm waiting to get the truck back to send a sample into Blackstone. However at 2600 miles on the oil change I did myself (by the book - get to op temp, pull filler cap, pull drain plug, allow to drain for at least 30 minutes, pull oil filter once just a drip and continue to allow to drain to reach min of 30 minutes). Truck has 27,400 miles with an August 2022 build date. Purchased the end of October 2022 with 34 miles on it. I use docs diesel fuel and oil filters, and either mopar or filter guard filters.

Anyways, I will update as things move along. The dealer noted that as soon as it went into regen they pulled it in and bore scoped the DPF noting it was clean. They've pulled it for a manual cleaning, test drove it and it started a regwn 27 miles into it. Starcase had them pull the MAF wires then send the readings in, and I believe that is what has led to this first attempt to fix.

I have found that PID and DPF Time to be horribly inaccurate. They only update at a regen, so @mbarber84’s being low is because it’s recently hooked up.

I’ve tried numerous times to make sense of those PID’s and can’t.

interesting that yours is that inaccurate - maybe mine is more accurate with my low numbers (about 160 miles (summer) or 240 miles (winter) between regens unless towing)

I don’t think it’s just mine that’s inaccurate based on other threads.
 
Someone mentioned either diet or trading for a ford. Ford is great but that power stroke is stuffed in there. I’d almost say go 7.3 gas which is a great engine in my opinion. Regardless hopefully Ram figures it out or I’ll be dieting too.

If this pass doesn't fix my truck I'll likely look at a Ford too. I'm with you, the 7.3 probably would be enough for my needs.

There's no excuse for these problems.

I'd delete but it'd kill my warranty. With my luck the lifters would fail.

So here’s a quick question:

Had a chance to take the truck for a 30 minute trip. Started out with “DPF RG %” at “11”. By the time I got to my destination that number was “46”. We ate dinner and after the truck sat roughly 1.5 hours, when I got back in the truck that value was at “14”. What does that value indicate? I was under the impression it was basically the regen countdown?

It is the regen countdown based on time or soot, whichever is greater.

Below 12 hours since last regen the soot loading causes it to bounce around like that. Usually 35-45 while driving and then after sitting it goes back to time or the “updated” soot loading.

Those readings seem normal, assuming you had a recent active regen.

Yeah I just finished a regeneration Thursday afternoon. My worst one in almost 8 months. A whopping 331 miles and 8 engine hours since the previous one.

exactly what mine shows when I have a relatively clean DPF - once I get into the 60s and above, it is usually a steady climb to a regen (unless I tow something)
 
I just noticed something strange on my 2022 Ram (5th Gen). While inspecting the MAP sensor on the airbox and the TMAP sensor on the intake elbow near the engine, I looked up the part numbers and they both seem to be for the 4th Gen Ram, not the 5th Gen. Could this be part of my regen issue? Getting bad readings from old sensors? I don't know why they would be meaningfully different but perhaps the ECU is programmed to read the new ones and not the old ones? I imagine during the height of the supply chain issues they could have put these in as a potential substitution? Pictures for reference. IMG_4089.jpegIMG_4090.jpeg

There isn’t a 5th gen HD Ram yet.

What part number do you think you should have?

My self to be sure I did not void my warranty I wound not use Docs Diesel fuel filters, I use either Mopar or Fleetguard fuel & air filter, as for oil either Fleetguard or Donaldson EFL 7349
