Regen indicator

[Jwskj]

I want to have a positive indication when my 2016 is in the regen process.
Does anyone know of a wire that I can tap into so that I can power a LED mounted in the dash to give me that indication???
To the best of my knowledge, there is no factory dash indicator to provide this indication.
I've got 15K miles on my truck and I periodically get a stinky exhaust smell that I think might be related to the regen process, but I'm not sure.
I never really noticed a significant reduction in the instantaneous MPG indicator, but I never thought to pay much attention to that.
The overall mileage with the truck is much better than previous CTD trucks so I don't have any complaints, I just want to know when the regen happens.
Anybody know how I can get the LED to tell me when it's happening??

Do not tap into any wires.There are aftermarket monitors but they are not cheap.In my opinion there is no need for the average consumer to know when the truck is in a regen.Aparently FCA agrees with me lol

 

[Jwskj]

Apparently, I'm not the average consumer because I want to know.


FCA may not agree with me, but I still want to know. I don't want an pricey aftermarket monitor or a power booster, just a simple indicator to tell me when the CTD is in regen. There has got to be an easy and cheap way to get this done!

 

[Bob4x4]

Since you are an engineer and not an average consumer tap away......................

How did you know I was an engineer?

 

[phantomusa]

Your profile says your a mechanical engineer

If you get a Bluetooth OBD2 dongle and the Torque app, I ***THINK*** you can monitor lot of the functions of the truck. I'm not entirely sure if there is a specific monitor for regen... but you would be able to monitor your DPF EGT's, which would let you know when you are in regen. I have an Edge CTS JWA "tuner" on my truck that has a regen light, not sure what triggers that light. I would imagine that if the Edge can tell when its in regen, the Torque app should be able to as well.

I don't care if I need to know or not either. I would love to know when the truck is doing it's thing.*

I remember when my truck first went through it. Had a haze of smoke burning off the exhaust tubing, but my first thought was that my truck was on fire. Would have been nice to have a dummy meter or light to let me know that it was normal.*

 

[Jwskj]

If I get it figured-out, I'll post the solution.
Don't hold your breath, though. My first project is to get the power mirrors to auto-close when I lock the truck...the good part is that I'm pretty far along with that project.

Are higher RPM's better to regen the dpf. 60MPH in 5th gear vs 6th gear / 30MPH in 3rd gear vs 4th. Or just leave the trans in drive and let the truck do it's thing.

Maybe because you can't find and read a wiring diagram but you know more than the guy who fixes them daily.

I notice slightly higher EGT's with an intentional downshift and higher RPM's (and throttling up a little) in most situations. Using more fuel will generally raise EGT'S. It also engages a bit more boost. Remember that torque management will limit your boost at low RPM.

Coastimg is zero or almost zero fueling so that will reduce your EGT's

Many MOONS ago when I was working for a Large Heavy Equipment Manufacture we were wrestling with this idea. Should the owner/operator know when the engine went into regeneration of the Diesel Particulate Filter. The decision was made that they did not need to know and the operation should be seamless to them. Why? The reasoning behind this decision was they would be stressing out whenever the engine went into regen, especially if this happen right before the engine would be shut down for any reason. Would the operator shut down the engine during a regen process at this time or wait for the 20 to 30 min's it could take? Would the operator operate the machinery different in the regen process? These were only a few of the questions we had when this anti-pollution device was required for diesel engines. As you can see the automotive industry also has followed this same path that the owner /operator does not need to know!

With the updated emission system on the 4th gen trucks when using the DEF (Diesel Exhaust Fluid) the regeneration of the DPF is less and very infrequent compared to the 3rd gen and very early 4th gen trucks with just the DPF system

On the 3rd gen and early 4th gen trucks there was a simply way to understand if your engine is in regen or not was to add an EGT Gage and probe into the system. When the engine is in regen the exhaust gas temperatures could be as high as 1450F during this process or around 1250F. When the regeneration is not taking place the EGT's could be between 450F and 900F, if you are not towing.

LOL..LOL.. You would want to know Regens... wait until you get the message thats 70-90% full massage, C'mon....I worked at Cat for 2 years under contract That the gag order has expired... Many of our innovation's were trump out buy the Bean counters... So thinking that your are getting favorable intel form the manufacture is generally water down Vision.... BOB4x4 C'mon how many work abounds you perform daily that FCA corp would not approve of, Its your professional Knowledge and expertise thats honor here..

My 2500 Cummins went into active regen on the way home from dropping my wife at the airport. I had my OBD2 sender and torque app on my phone monitoring EGT #1, #2, &#3. I was driving unloaded 55-70 mph and got the 100%-70% count down along with the dinging that always accompanies the (active regen) EVIC message. I realize that active regens may also occur with no message if the DPF is not 100% full. This happened Thurs. March 2nd, 2017 so it is fresh in my mind. The regen only took about 10-15 mins at hwy speed and was complete just as i reached my off ramp. EGT's on the 3 monitors were not what I expected. I would have expected 1100-1400°F EGT's. But the EGT's pretty much topped out at 973°F (EGT sensors#2 &#3 were the highest, which i was also surprised to see) .

This was an active regen with EVIC notification that didn't seem any different than normal operation passive regen.



Here is my expeeience with passive regens now that i have an OBD2 monitor: It does seem that when passively regenerating, the third sensor gets hotter than the second sensor because the burning soot helps create a tiny bit more heat. But before it passive regens, the 2nd EGT seems to be higher because the soot is still absorbing heat and hasn't yet started combusting. So with passive regens, it seems the temp differential between EGT sensors helps me see passive regeneration.

Best way to monitor things on these trucks in my opinion is with the Edge CTS Insight. Mine works great for indicating when DPF regen is active and monitoring a pile of other items.



With the way these trucks are setup on CAN-BUS i wouldn't be taping wires for nothing.

 

[RB33]

I have my Edge CTS 2 Insight set up to monitor 12 different PID's with the last columns on the right showing EGT's 2,3,4 & 5. and I think 3 and 4 are the ones that get the highest during a regen, I have yet to have any indication on the EVIC about regens so I assume the passive regens are taking care of the soot. Of course, I only have 2500 miles on the truck to date. Correct me if I'm wrong on any of asumptions.

I didn’t know there were 5 EGT sensors. I think my 2013 has only 4 EGT sensors.
