DPF Regen

[kevinkidder]

Thank you everyone for the useful information about the DPF Regen. This has really helped me.

I guess I have a related/unrelated question then about the ScanGauge. I went to their website, and while everyone here is talking about ScanGauge 2, they have a ScanGauge 3. Is that just a newer model?

Also, a recommendation from a friend was to look at Tazer JL from Z Automotive. Is that useful for this? Or is Tazer JL something else completely?

Thanks again for putting up with my insane questions. It is my first real Wrangler and my first diesel.

I don't know about the ScanGuage 3, but the Tazer JL Mini is something completely different. It adds lots of functionality, but nothing related to DPF regen.

I think we all have older Scangauge IIs. The III is likely the way to go now. On closer look, the III is color, has more simuluateous displays, and a larger footprint. I think I'd stick with a II.

As referenced, the Taser is for other stuff. I use mine to adjust for 35s and to defeat my ESS.

Can't disagree with you on becoming attuned to your own vehicle, but the OP was looking for a nonintuitive method for tracking his regens.

A few diesel-centric readouts would have been nice on the Ecodiesels. Especially since many of us are new to diesel engines.

Agree with this. Should have been trivial for a screen or two in the EVIC for diesel info. The 4xe gets specific gauges.

IDK, that looks nice. If the dims align with my voswitch I may pull the trigger.

--UPDATE--

So I did pull the trigger on the ScanGaugeII. I love it. It is the right size/profile for what I need. After a bit of local driving, the DPF finally climbed to 80%. Once the regen started, I hit the highway. All it took was about 10 miles of driving for the DPF to go back down to about 14%. I was showing my buddy how using the turbo can cause the DPF to climb, but to my surprise, after giving it some get-up-and-go, it went down to 8%!!!

So to answer all of the questions I didn't know before:

Regen starts at 80%
Regen ends at 15%
Regen takes about 10 miles of driving at a normal, constant pace.

One question for anyone with a ScanGaugeII, I want to add the info for the turbo temp.
X-Gauge Categories » 3.0L ECODIESEL (scangauge.com)

Any idea which shows the Turbo Temp?

Thanks again all!

Scangauges are cheap, unobtrusive, easy to install, and highly informative. I actually brought one with me when I picked up my JLURD. It's operational after a five second install. Ten more minutes, when I got home, to get the cable routed perfectly.

It's like driving a stick-shift sports car without a tachometer - you can do it, but why would you?

I drove many manual vehicles and barely acknowledge the tach. I hate the look of the scangage and wouldn’t install it. 18,000 trouble free miles so far. Not that I should have trouble on a year old vehicle.

TRB is turbo temp.

Just FYI. Active regen should start at 80% and end at approx 8%. It should not be stopping at 15% if you are letting it cycle.

 

[Tread4Lo]

I will agree the regen does stop at 8%. Though, it does seem the percentages up to 20 come on REALLY quickly after a regen.

Even with highway driving (NETX to Austin), I couldn't get my DPF below 24%. This was mix of Texas highways and 80+mph on I-35.

The 80% and 8% are built into the algorithm. The system for Active regen has these set as triggers.

Passive regen, which is what you are referring to above, will never bring you all the way down.

Depending on how you are monitoring your regen status to will see none, passive, and active. If you do not have that ability, monitoring your DPF out temp will be another clue about active regen. Temps will hit 1100-1200F during active.

 

[Tread4Lo]

Yes. I was mentioning both. Thoughts some times get scrabbled.

I do not monitor DPF temps, which I assume the ScanGuage would do. I just need to program it in. It would be more useful than the Total Number of Regens (TNR for ScanGuage).

There is literally no benefit to watching regens or tracking wen they happen or complete. I was always surprised how many people on the Ram forums were obsessed with watching the DPF screen and what precent it was full. I am glad to hear that Jeep did not include that in the gauge cluster!!

I have owned 3 Diesel Rams and now a F350 Powerstroke - just drive the truck/Jeep and enjoy it.

I am picking my EcoDiesel JLU on the 6th and have no plans to worry about regens.

I like to keep tabs on it to make sure I do a complete cycle from time to time. I prefer not to interrupt a regen when I don't have to.

There is absolutely no reason to worry about interrupted regens. The process will pick up where it left off ...so many variables to what triggers a regen but do not fret...they will happen as needed regardless if the vehicle is shut off during a regen.
