That may have been partially due to the way the truck (and the MAF) “learn” or “adjust”. Rams own document on P2459 clearly state that, depending on how the truck is driven, it may take thousands of miles for it to adjust when a different style air filter, a new MAF, or other intake system are installed.
Ahh how the story continues. I could’ve sworn they had an injector downstream.
What is more aggressive about their regens? It’s my understanding they regen every 500 miles so I suppose I might consider that somewhat more aggressive. On the other hand, the operator can control when it goes into regen (if the option is enabled) and it’s sounding like the newer ones have an injector downstream which I would think would help with diluted oil. It would be great to not start a regen 10 miles from my house on my way home from work and start the regen after it has been warmed up so the regen could be more effective the next day or long drive. This thread is at 64 pages now so I’m assuming most here don’t make it to 500 miles let alone the Rams designed 24hr regen. There’s plenty of people out there that don’t have the problem and aren’t on here but I also know owners that have the problem that aren’t on here. It might sound like I’m standing up for the psd but I’m not and I still enjoy my truck. Cummins all the way. I’m simply gathering information. I’m sure my issue is somewhat produced from the way I drive (mostly highway and 12% idle) but there’s a lot of instances that make me sometimes think otherwise. I trailered my TT over 200 miles all highway and 20 miles after I unhook it, it’s ready to regen again. I have since gotten a monitor so I can now look at much more data and it’s very eye opening.
Do they like them and do they seem to mind their regen frequency? I’ve seen a few threads in their forums and the ones that I’ve briefly looked at they seem to be of the mindset of it is what it is. We have new F450s at work. They definitely regen a fair amount but I don’t pay as close attention to it since I’m not always using them. They also are carrying a good amount of weight behind them constantly which will help with to getting a good regen and the frequency of them. I like the Ram interior a lot more. Sure it’s not the equivalent trim but the dash, doors etc have cleaner lines in the Ram.
I agree, they all have their own issues and for a lot of people it comes down to brand loyalty. They all have pretty similar quality and amount of issues. That’s horrible about your friend. How did he get back?
Same. Know a guy with a duramax that had all injectors replaced within the first year of ownership.
I just checked the NHTSA’s website under manufacturer communications for 2022 Ram 3500’s. Nothing on the DOC. Some other recent stuff from this month though. Could be so new it didn’t get uploaded yet.
Mine acted crazy this morning. Left home with the DPF gauge on zero and 80% on the SG. SG jumped to 99% and truck went into regen in about 10 miles after leaving home. Wife had a Dr appointment so I dropped her off and got back to the interstate and got it finished. I don’t think I got a real good regen though with all of the stopping and starting. SG dropped down to 7.8 after I stopped for a while but it’s already back up to 32% after driving for only a few minutes. I was going to do an oil change after the regen but I may do a parked regen first. Had 20 hours and 644 miles in this cycle but a good bit of idling messing with the new SG III. Time on the SG and the EVIC did not line up when the regen occurred. The SG lost about an hour and a half recently and I don’t know if it was from having the key on not running and the EVIC recorded it as idling and the SG was running off of the regen timer in the ECM. IDK
OLEJOE, You don't have to start and run the engine during setup, just set the ignition on run then just tap the SG3 and it will light up and you can do whatever you need to. If you stop doing anything with it for a seconds it will shut down. I quit running the engine when doing any setup, moving or changing PID's etc. After a regen like my last one it was down to 8.63%, when I cold started the next day and drove it it went up to 30+%, then the next day cold start it was 15+% give or take (short trips), don't recall for sure. In a previous post with with a trip monitoring both, all the pictures of the dash with SGII, it was showing 45% at 18 hours on the SG, then went to 0 and stayed there with 22 hours on the clock at the end of the trip. A couple days later when I drove it with the 22 hours to 23+ hours it went into regen, and the dash gauge remained at 0 the whole time. I'm not experiencing frequent regens, so maybe there's a reason to monitor both, but for me I would think it adds to the confusion of what going on!
This was my first regen using the SG III and it was kinda weird watching the Soot Load % go up like it did and getting the alert when the Regen State went from off to on. Also watching the egt’s running 1000-1100 degrees. Around here you idle it because it’s 95 degrees in the shade. I did do the parked regen but nothing changed on the SG as far as soot load and it only lasted about 15 minutes. Idled up to around 1000 rpm but I wasn’t running the SG since I used the JScan to initiate it.
