How often has your exhaust system done a Regen

[Divided_Wood]

So lest anyone get confused here... this is a perfect description of an active regen. Happens when DPF gets to 80+, EGT3 goes to 1000+, definitely can smell something very hot, DPF rapidly drops to under 10. 6-7 over 3500 miles is about right too.

Passive regen is when you're on the highway, and DPF slowly drops by a percentage point a minute or so, no temperature changes.

I don't know what the iDash displays exactly... 0/1/2 I guess? My Scangauge just has a regen-active (RGN) readout (ON/OFF) and the top description is exactly what happens when it reads ON. Passive regen, where DPF drops a few percent, reads OFF.

Sorry, I guess I am just going by what the iDash says. The only regen statuses I've ever seen are "off' or "pass." I think of the passive, background regen as different than a regen where your Jeep dash tells you to maintain current driving condition until the process is complete, but maybe that's not correct. Either way, I've yet to see one of those and only know the other regens have happened because of the iDash.

No worries, it is pretty complex and confusing TBH. Like @BEERviper has been saying here, if you see anything on the dash, it's basically a last resort because the Jeep has been trying and failing to silently run an active regen in the background. If you do see the warning on the dash, pay attention and do what it says, because the next step is disabling itself, and having to be towed to the dealer for a forced regen.

(As long as your usage includes some long highway trips, it should never get to that point.)

I got my Idash installed today. So i will be paying attention I hope.

I'm not familiar with how the iDash is programmed, but there are 2 different types of regen that you would need to pay attention to (although I'm sure you know this)
DPF Regen status = 0 means no passive nor active regen
DPF Regen status = 1 + DPF regen type = 0 means Passive regen
DPF Regen status = 1 + DPF regen type = 1 means Active regen

These are the PID's that can be read from the OBD2 port...
If there's a way to program the iDash for regen type you would want to know that.
Also knowing the soot level % will give you an idea of when you might be hitting an Active regen (typically when it hits around 80%).

Will be interesting to see if the stats coming from the iDash differ from the OBD Fusion app that I use.

On the idash the regen status will show OFF/PAS/ACT you can also set an alert for active regen, set the high parameter to 2 for the active. If you set it to 1 the alert will go off during passive regen which is almost anytime the DPF temp is high enough, which is very annoying.

Nearly 1k (70% city) miles and I’ve had 2 active regens and one interrupted. I use the Torque app and have many of the same PID’s monitored and know I’m in an active regen when the DPF gets into the 1200* range.

I assume I've had a regen at 800 miles and 1300 miles. Nothing indicated on the dash, just the Jeep smells like its on total fire when I park. All temperature gages were reading normal when this happened.

That sounds about right

Mine did a passive regen last Monday. The way I found out. My SOOT% went from 77% to 4% on the iDash. Didn't even know it did it.

I've kind of quit watching the soot levels since 95% of my driving is the perfect situation to keep the system cleaned out. The Fusion OBD is still reporting 500-700 mile regen averages.

Do you mind sharing what parameter you are monitoring to get the soot% to show?

The top reading. DPF SL % (SL= SOOT LOAD)

I need to get an iDash gauge. Do you know if anybody makes an A pillar piece that mounts the iDash for Gladiator?

Haven't looked.

Interestingly enough, mine doesn’t have that option. I’ll try a firmware update and see if that does the trick.
