Is there no EGT gauge on the newer Rams

[NIsaacs]

I have the Edge CTS and never notice the plug at all.

IIRRc the wiring comes out of the connector at a 90 degree angle-not real obtrusive.I have seen a few that have run various devices long term in the DLC develop poor fit in the terminals

Background:

Earlier this week, my truck went into active regen. Haven't had the EVIC message on active regen for over 2 years. But Tuesday afternoon while taking my wife to the airport and stuck in rush hour traffic, my EVIC gave me the active regen count down. DPF 100% full, 90% full, 80% full, 70% full. Then after 70% it stopped active regen and said that regen process was complete. However, I suspect the DPF was still about 50%-60% full, but the truck decided that was OK.

I put a trailer behind the truck and loaded my wife's car on it. Drove it like i stole it.


Edit: The EVIC was dinging annoyingly the entire trip to and from the airport (except for the last 5 mins). Seemed like it was constantly going in and out of Regen. And every time it did, it dinged at me again. My wife told me to get that obnoxious dinging noise fixed. I think I did...... at least for a while?

Never had any dinging, for that matter in nearly 3 years of ownership never have been aware of a regen. Is that something just on the 2013's ? My 2014 has never had anything pop up on the EVIC about regen. Everything I have read about these trucks, no news is good news on the regen

You get the warning once the DPF is to a certain percentage clogged (90%? I don't recall exactly). This will only happen if the driving time/habits of the truck do not allow ample time for a passive or active regens.

Wow Newsa.......you dwell a bit much! #ad

So yesterday, i went and rented a uhaul car trailer for 4 hours, loaded my wife's car on it and put it on the hwy for a while. I did this for no other reason than trying to get the EGT's up.

Sounds like truck micro-managing to me

Thanks, towing a 38' fifth wheel probably takes care of that, not a lot of city driving.

Absolutely.

I have a 15 mile, mostly highway commute to work everyday. Even this is enough to prevent the warning message as I have never had one in the 2+ years I've owned it. Obviously it still does active regens occasionally (without the warning message) but I rarely notice them.

You're probably right. But that dinging (15-20 times per minute -same ding that alerts you to a CEL or other EVIC message on 3 in screen) was driving us crazy. I honestly would do anything to get rid of it. Rush hour traffic is bad enough without all that racket.




I looked up Joe's column/article in issue 86 of TDR. Hope I don't get in trouble for posting the first paragraph here where he says EGT monitoring was the biggest reason for getting the Edge Insight. Excellent article that explains how he uses the device. Must Read!

The thing is.....you could have just driven around (preferably highway) without a load and it would take care of itself.....as apparently it already did. Active regen does not require the engine to be "worked".

I have done that in the past. But it takes a LONG drive to get any passive regen benefits and it didn't seem to have a lasting effect. On the hwy (without load), my turbo doesn't even seem to be doing much. Under a towing load, I was getting more turbo boost and i suspect higher EGT's.


I don't see fuel dilution after one or two active regens. But after 5 months and multiple active regens, I do see evidence of fuel dilution in the form of oil registering higher on the dipstick.

I suspect hwy driving unloaded is enough to keep DPF soot levels where they are. But doesn't efficiently burn off already-accumulated soot.


I believe the active regen that it wwnt tbrough did not clear out 100% of the soot from the DPF. It counted down to 70% and then said "Exhaust regeneration process complete". But i believe the DPF was still 50%-70% full. Still had a check engine light after the active regen. But the towing I did took care of that.... and the CEL cleared itself.

If your truck needs an active regen, it will do it. It will do it without you having to load the engine, it just needs time, like a bit of highway driving. The extra heat needed comes from the added fuel from the injectors on the exhaust stroke. It does this without having to work the engine hard.

It looks to me like you are confused on what the terms active and passive regen are. Your truck will frequently go into active regen when needed and you will not get any kind of warning. You only get the warning if the truck hasn't been driven enough for an active regen to finish the job and the DPF has plugged to a critical point.

During a passive regen, your truck isn't really doing anything special......the ECM isn't calling for a regen at all. It simply means that the engine is working hard enough that it is generating enough heat on its own to reduce the amount of soot it creates, as well as be able to burn it out of the DPF.

It sounds like you are just going to "believe" there is a problem regardless of what your truck tells you......but do you see how illogical it is to rent a trailer and tow a car around to fix an imaginary (in my opinion anyway) problem?

Yes, I know that my EVIC only tells me that there's an active regen when the DPD i 100% or nearly 100% clogged. And O can tell it is actively regenerating at other times. My experience with the acctive regen us that it will only tell you it takes the soot level down to 70% because the truck can run efficiently at 70% (cligged DPF). I'm not at all sggesting others do what I did by renting a trailer and towing. If my truck does another active regen (with or without message), then I know my experiment didn't work and didn't clear the DPF. I prefer passive regen where the truck doesn't do anything except work hard to active regen due to my fuel dillition issue on the oul. After 5 months on a oil change and one or two active regens per month, some of the sdded oil seeps past the rings into the sump. I don't believe U have an injector problem because i only see oil dillution after multiple regens.

A couple of months ago, I went off roadimg (put it in 4x4 on an everglades access road). It helped a bit to clear out the DPF. Didn't have time to drive out there this week.

 

[kthaxton]

Lol!, well 4wd certainly wouldn't have anything to do with it!

 

[Newsa]

Using 4x4 to put a load on the engine similar to towing

 

[kthaxton]

There isn't much load there from engaging 4wd. Some, yes, but it would be an imperceptible burden for a Cummins.....probably like driving an AC compressor. Certainly not enough to raise EGT's any notable amount, and even more certainly not enough to perform a passive regen.

There is much more resistance to movement (or "load") going highways speeds just from wind resistance. Wind resistance increases exponentially the faster you go.

I'm not going to argue with this statement. You could be correct. But it was a 3 hour trip (round trip) just to get to the dirt road on which i was able to get the RPM's up in 4th gear.

Edit:


I don't know why it posted this twice. But I wanted to add that it was 20-30 miles in 4x4 on the dirt road.

I would say the drive time is what gave you a successful regen.

I love my Edge CTS Insight on my truck! I had it for monitoring things on my '05. I have not drilled and tapped the EGT probe into the manifold... not sure if I ever well. I watch EGT1 when pulling hard, but considering adding the probe in the manifold just to help determine when it is safe to shut down the truck. I also love the fact it tells me when the truck is in a regen, VGT position, and trans gear & TC lock status.

I agree with 12v98... the new trucks probably won't ever hurt themselves in stock form, but I also see NEWSA's point... I like to have my finger on the babies pulse.
