How does Edge Insight indicate a regen?

[DMosby]

I really hate the idea of making a lot of short trips with my 2008 RAM 6. 7 trying to regen and having no way to know that this is happening. I have seen people mention that the Edge Insight will alert them of a regen taking place.



I just received an Edge Insight. I have not installed it yet, just a really fast read through the manual - a more through read will come tonight or tomorrow. So far I have seen the following:

TRK Soot = Truck Soot Filter Pressure

I have not seen anything regarding indication that a regen is in progress. Can someone with an Insight tell me what indicates a regen and if this is a parameter that must be selected?



I have a turbo temp gauge and boost pressure gauge located near the mirror. Other than the ability to set an alert on turbo temperature is there any benefit to connecting the temp probe to the Edge? If I decide to do this can I simply run this in parallel with the existing gauge?

A quick follow up to my post. When the car was in for ERG valve replacement last week the service advisor told me that I had 40 regen attempts and no successes. Is this data that I can read with the Edge Insight?

I think perhaps your trying too hard to make it complete a regen. If you are not having a DPF full warning on the overhead, or a check engine light with a DPF plugged code, the truck is doing exactly what it was designed to do. The whole idea is that the regen process was to be transparent to the customer. It is perfectly OK for you to shut it down during a regen, and it is possible based on your specific duty cycle to NEVER complete a regen. That does not mean the DPF is going to fill up, but that the system is reducing or holding the soot load steady. The newest flashes have done a remarkable job at keeping the DPF from plugging.

The most important question to ask and have answered is what is the soot load of the DPF doing. If it is not being reduced or holding steady while your driving there is some other underlying problem with the system, and the DPF will fill. Trust me, if you drove 1500 miles with no regen occurring, the DPF would have plugged long before now. Your truck is working as it was designed, so if it were mine I would forget about what is happening behind the scenes and just drive it. The DPF will not plug unless you have some other problem. Forcing a manual regen would just buy some time before the DPF plugs.

I am not trying to force a regen. If I drive this thing in town, making lots of short trips I want to know if it is continuously trying to regen. I do not want to make two weeks of very short trips with it continuously attempting a regen.



I have now seen several posts that lead me to believe that the Edge Insight will indicate a regen. In fact the back of the box states "And for owners of new diesels with DPF traps, the Insight displays DPF regeneration status". I can send Edge an e-mail but as I know there are Insight owners on this list I thought I would ask here and see if someone could tell me the manner in which the unit indicates a regen.



I have a 2008 RAM 2500. At 3524 miles the turbo was replaced. At 5249 the EGR valve was replaced. That was just a couple weeks ago. The service advisor told me that it had 40 regen attempts with none successful. He also told me not to idle it, as soon as oil pressure came up to drive, and unless coming in off the highway towing to just shut it off. I was told that my short trips killed the EGR valve.



Yes, I do have the latest flash and ever since the turbo replacement have been driving with exhaust brake on.



I think the basic truck is great and think the engine is great. Plenty of power, I don't need more. But I think the EGR/DPF combination is a complete and utter disaster. On a hot day can I shop for a half hour while the truck idles and keeps my wife cool inside? Nope. Can I make a lot of short trips around town without it wasting fuel in constant regen? Nope. I told the service advisor that no one told me I couldn't use it around town when I bought it. His reply was "We didn't know when you bought it. People that use it on the freeway towing will love it and people that use it for short trips won't be happy with it. " There is his story - short trips and you won't be happy.



Anyway, I'm an engineer and engineers have a personality trait of wanting lots of data. So if someone knows how the Edge Insight indicates regen please let me know.

I think you’re over reacting. Have you ever seen a message in the overhead about DPF load?

If not, you can continue to drive the truck as you always have. Contrary to what your service advisor told you, you can idle it, especially with the latest flash. Starting about two flashes ago, they introduced "net zero" idle where the truck will reduce soot load or at worst hold it steady during idle. You might have noticed the idle speed go up while idling. This is the net zero strategy working.

I don't know what happened to your turbo or the EGR valve, but with the latest turbo and EGR changes along with software changes the trucks have been performing very well under all but the most severe duty cycles.

You can minimize idle times to keep the soot load down, but I don't think you have to drastically change your lifestyle to do it.

I have the insight and it flashes when the truck enters regen. Of course it hasn't flashed in several months... No DPF. .

I use the idle up feature that I had the dealer enable when I bought it. I turn it on when the truck has been sitting in the hot sun do get the A/C going before I get on the road. If I am in a store or my wife is going in to pick up something quick rolleyes: Yeah right ) I idle it up and all is happy.

What I was trying to determine was if the Edge Insight had to be set to monitor specific parameters in order to display a regen. I'm pretty busy at the moment and wondered if it would indicate a regen if left with the default parameters for a few days. The answer is that you must choose the parameters associated with a regen. They are under the Chrysler specific group.

Hi DM
on my insight I have a profile from Coalsmoke, monitoring the following parameters:
RG filter
Lst regen= counter by seconds
Regen Soot= off/on
Regen Sox= off/on
Regen Cmp= count
Regen Des= count
Regen Inc= count
on my 07 6. 7 I have Cmp=12, Des=217 and Inc =0 I'm guessing Des means discontinued?
my Rg Filter right now shows 7. 9. I, also make short trips, work is 11 miles each way. I try to take the truck out on weekends and work it to complete a regen watching the timer to time when to drive it longer. hope that info helps

Can you remove DPF on 09's

DM,



The Insight can monitor Regen status.



"And for owners of new diesels with diesel particulate filter (DPF) traps, the Insight displays DPF regeneration status. "

The answer is that you must choose the parameters associated with a regen. They are under the Chrysler specific group.

My Edge Insight came with 4 default values on each of 4 displays. One page of mine (4 values) is all about regen right out of the box.
