Regens after a month of ownership...

[gerlbaum]

If I had known this I would have just went diesel originally. Forum fear kinda scared me away from it. I was hoping that jamming it all in once place might be useful to someone else down the road.

That and a new dpf is $750 from mopar and 6 bolts hold it in. Then again the 8 year 80k warranty means I don’t really have to worry. I, of course, prefer not to have the system at all but it’s been out more then a decade and it’s literally on every light to million mile heavy duty diesels throughout the world.

I think deletes are running $2100 when all said and done and that’s assuming you install it yourself. That’s a lot of dpf canisters.

The 442 lb/ft at 1900 rpm made me really happy (510 lb/ft with the Banks tune).

Social media can suck a lot of times.

Has anyone tried one of those cheap Bluetooth OBD scanners and a phone app like TorquePro instead of buying a scangauge or banks?

I have one. It’s ok. I hate having to connect my phone every time. Plus it’s become illegal to have your hand on your phone while driving in my state.

I have the scan gauge and it’s really great. I do not have it plugged into the security bypass.

I agree that a ScanGauge is absolutely necessary. I only wish that the gauge showed the soot levels dropping as it approaches 8%. Mine shows the regen is on, runs for almost exactly ten minutes, and then turns off and displays 8%. So...it goes from 80% to 8% without showing the intervening progress. My only (minor) "complaint".

Driving a diesel without one is akin to driving a manual without a tach.

Mine will sometimes. Like when I’m driving slow during a regen, it will show it dropping. Once I’m above 20 mph it won’t show it.

Oh, and get a ScanGuage II! I can't imagine having no visibility into the process. That little gadget makes it so much more manageable for me as I'm someone that likes to know the numbers and details.

[Quick trivia: My Jeep image below was taken in the cemetery where the original Night of the Living Dead was filmed.]

Jeff, Lots of good information in your post. I don't have a ScanGuage II, so I never know what is going on with regen or my DPF mass. I wish this data was available on the IPC display. I have ~15,000 miles on my 2021 JLURD and have never had a forced regen, that I know of. About 50% - 60% of my driving is at highway speeds so I assume this keeps my DPF flow restriction fairly low.

BTW, I see an undead hiding back in the tree line.

Yeah, it should be available without the needed gadget. I agree. I’m curious as to whether yours has. Based on what mine does, it’s likely done a few active ones but your driving allows it to complete so you don’t get the message.

It saves the total number of regens, so if you had access to one you could check and you’d see the history.

Ha on the undead part! We were there geocaching. It’s a pretty amazing little cemetery. It still looks just like the movie, with some additional cell towers.

Do you mind sharing the different sensors you use for TorquePro and what they mean?

I may be wrong, but I suspect that you've had dozens of regens without knowing it.

So I’m not 100% on the regen PID because I didn’t use it long enough but here’s what I had for my dashboard:

PID “percentage of soot mass” = soot mass percent (obviously)
And
PID “turbocharger a turbine outlet temp” = EGTs
And
PID “boost” = boost

The regen status - whether it was on or off confused me. This is why I got the scan gauge too. It has some sort of logic built into it to take the guess work out. I never use it long enough to figure it out but these were the PID I had:

PID “dpf regen status”
Or
PID “requested regeneration state of dpf”
Or
PID “dpf lamp”

The gauges would either be “0” or “1”. I took that to mean “0” is off and “1” meant regen is on.

I know you can also do user defined PIDs that include some equation. But that’s beyond my capability - someone smarter than me may know. If you find one it’s easy to import it or just recreate it.

Very informative. I guess I just like living on the edge, I bought the longest extended warranty, I put in diesel, def, do required maintenance and drive the shit out of it lol

It does smell during a regen! During normal driving, there’s no diesel exhaust smell. During a regen, there’s certainly a noticable acrid burning smell to it. My six year old asked, “why does the Jeep smell like a hot grill?” one time when I stopped it early to figure out what might hleading up to this. You can have the first two processes happening and never even know it.

The smell thing is either subjective or they don't all have the issue.

My 2007.5 Duramax smelled terrible during a regen.
2020 F350 doesn't smell terrible, but during regen there is definitely a somewhat unpleasant odor. In the Ford it is kinda hard to miss a regen as I eventually think "what's that smell?"
Wife's 2020 3.0L Wrangler has about zero smell during regen. I think you might (might mind) be able to catch a faint whiff of something at a stoplight, but otherwise nothing. If you're not paying attention to the scangauge you'll miss the regen. But you can smell the urea injection seemingly all the time.

A lot of people are so afraid of anything outside their idea of what a jeep should be they'll try to keep others away as well. Sorry you were lead astray by the ignorant ones, diesels are awesome!

I still do have tons of questions that I can't find answers to.. things like "when do stations start supplying winterized diesel? How do I know?" I'll update as I figure this stuff out. =)

If you buy your fuel from a well traveled truck stop, you shouldn't have to worry about if it's the winterized stuff or not. I do recommend keeping a can of fuel treatment during winter regardless, when I lived in upstate NY the temps got into -45 and the engine wouldn't start for a day . I walked to the store and bought some treatment and learned a tough lesson that day!

A scanguage or Banks data monster is a great item to have for monitoring.

How did you get your DSR working? mine is always showing 0.

 

[Ruby Clatterbox]

Yeah, I think there's a lot of misinformation out there about the diesel that turns people away from choosing it as an option. For me, it's very reassuring to hear that clatter and feel the torque in off road situations. I absolutely love mine! Funny thing, I had a ScanGauge 2 sitting in the closet from a previous car that I thought I'd never use again. Turns out it works on the diesel too. It's a great addition to monitor the state of the soot mass.

Mine too.
