3rd Generation 6.7L Engine and Transmission FAQ's

I've had my truck for about 2 months now with about 3000 miles on it. I've yet to see it go into regen. When did you first notice your truck in regen?
 
If everything is functioning the way it's supposed to, I don't think you will know when it is in regen. I've got a little over 5000 on mine and I can't say for sure it has ever regened.



I suspect it might have once or twice because the tone of the exhaust changed a little bit. It had a different tone to it, almost a low roar, though not that loud.

In 3000 miles of driving your truck has performed a regen but without gauges it is very difficult to detect the occurrence as DBoggs stated. If you are driving at steady-state highway cruise speed when the computer activates a regen you will never know it. If the truck is being driven around town in stop and go mode the driver can detect a slight increase in exhaust sound level and a slight throaty sound or roar. You may also notice a very slight momentary reduction in off-idle throttle response followed by slightly stronger acceleration for a given accelerator pedal movement.

The computer programming that manages exhaust regeneration was done well and it is almost imperceptable to the average driver. Over time as you become more familiar with the truck you will probably detect the slight changes but without an exhaust temperature gauge it is not real evident.
 
Harvey is also right about the throttle response, I have noticed that I get a little stronger acceleration if I'm puttering around town or something like that. I never put that together with regen though. Ya learn something new everyday.

Thanks for all of the replys gents. I guess I was expecting it to more ov an "event" than it has been. I also thought that something would come up on the overhead that said "regen in progress" or something like that. As for the comment regarding milage - I'm averaging a steady 15mpg (hand calculated) - which is acceptable to me (mainly because it's hard to stay off the power :)
 
I never really knew when mine went there but now that I have got my guages hooked up I can see an increase in manifold temp when it goes into re-gen.
 
The type of driving you do really does make a big difference in regens. Mine is a daily commuter of about 20 miles (takes 40 minutes) each way of stop and go with a top speed of 45mph. about every two weeks I take a 40 mile trip on the freeway at about 60mph.

I have the Edge Insight guage and with it you can track almost any of the trucks sensors. The trucks system has two EGT sensors post turbo, one before the Nox absorber and the other before the DPT. The guage also monitors the DPT load and the time since the last regen. Normal dirving keep the EGT around 600 to 700. Regen jumps to 1,100.

My driving causes a regen every 4,500 seconds or about 1 1/2 hours of running. If it is not able to complete a regen sometimes it will restart one as low as 2,000 seconds. If the temps are higher or on the highway it can go as long as 15,000 seconds. My DPT load varies from 29% to 70% so I have never seen a overhead warning.

When a regen starts it bring everything up to 1,100 degrees for about 8 to 10 minutes then if conditions permit it finally starts the de-soot phase of the regen. That is when you see the filter load start droping. The coments about power are correct, very noticable at low speed and starts from stops. Nothing at speed.

Mine started having codes at about 4,600 miles and when the pipe wrap and new O2 sensors with the AY flash was done at 19,000, no more codes and mileage when from 13. 4 to 14. 6 city and 15. 2 to 17 highway. They had also replaced the turbo back around 12,000.

Maybe see you folks at May Maddness.

Estarns - thank you for your detailed reply to my question. I am planning on adding the Edge Insight to my truck next month. A little off topic, but are you happy with it's performance? And how much did you pay to have it installed?

Good information.

Your detailed explanation combined with the original poster's question and the other posts is the first and best fairly detailed explanation of when and how regeneration takes place and how to detect it. It is useful for new owners. I've asked administrators to consider saving it as a sticky thread for future reference for new ISB6. 7 owners.

The edge insight just plugs into the OBDII port. Run the cable by the door up to the top of the dash and plug it in. I also got the dash pod to mount it. It uses double stick tape. Most people think it is factory installed. I paid $350 locally. I plan to later add the EGT probe when I get time to drill the manifold. Updates can be done via your PC plus you can record performance and display it on your PC.

I have the Edge Advantage which is the complete system. . You will be surprised how many times you have shut you motor down when it was in Active regen. . Their are as you may know Active regen that takes 10 or so minutes and Passive regen as you are driving it on the freeway. When it is in the Active mode, if you put the truck in park it shuts it down. Do this enough times and I am sure you end of with a clogged DPF filter. That is why you want to install the Edge. . It helps let me know that if I didn't drive through the Active regen it is going to come back on and I need to be prepared to drive through it. Kind of like a self cleaning oven that you never let finish it's cleaning cycle without having the guage. . I bought mine not for the power boost function but for the turbo timer, and the guages and of course the alarms that you can set one being when Active regen is taking place. . One hour to install plus the pyro... be careful tapping the manifold... if you are handy you can do it... .
 
About 5,500 miles, my overhead console told me it was time to change the oil, and when I reset the indicator, it did a Regen the next time I drove it after the oil change.



I heard a chime, and it said on the OH console the DPF was 80% full, and it was going into Regen mode. I was on my way to work, and I couldn't get over 40 mph for about 10 minutes. Once I got up to 55 - 60 mph, and was able to pull a small hill, it seemed much happier.



I've got almost 8,000 miles on it, and it seems to be just fine. I'm more concerned about EGR soot buildup.
 
The only reason you got the message is that your filter was getting full... I incorrectly stated above that I had an advantage. . It is call the Juice Edge with the controller. . Without having the guages you will never no when its in regen either passive or active. I drove my truck to work yesterday and in the 120 mile roundtrip in was in passive regen constantly while only for two second or so. It went into active regen one time... . without knowledge you will most likely being turning your motor off while it's in active regen never totally cleaning the filter until it's almost too late. . Installing regualar gauges will not tell you when it's in active regen only will show you the increased egt for the passive regen... . hope this helps... well worth the $800 investment
 
I have the insight and it's great for monitoring the engine and clearing codes. . Which I seem to have a lot of since I went with the delete kit. .
 
What can you say about the delete kit. . i. e. what is the parts needed, brand, and cost as well as benefits etc... thanks...
 
Fellow members, the forum administrator made this a sticky thread for retaining the detailed info about the regen cycle.

Lets keep the thread just for comments or questions about regeneration and post other subjects in new threads.
 
Great information all. Question for 1NebelO and EStarns - what DTC (Pxxxx?) code(s) do you program into the Edge Juice or Insight to watch for, that will tell you when Regen is in Active versus Passive mode?

To answer the question about what codes your program. . First you can't program any codes as the Juice reads codes as a function. It has nothing to do with Active and Passive regen... Passive regen is on going when you are running down the road as you can see it on the EGT window. It will go from 750 egt's to around 1050-1150egts. It does this constantly and seemlessly... I have on one of the four windows active regen on or off showing on the screen. I also have it set up as an alert so... . when I am going down the highway, the alert comes on and stays on until I push the display buttom. Then it goes back to the regualar screen which can display up to four functions. I have trans temp, engine temp, egt, and regen as my four screens. The regen will say on for around 14 minutes or so and the egt's soar to 1200-1300 during that time. . Without having this whole setup you will never know when it's in Active regen. . Example from yesterday is that I went to Lowe's 1 mile from my house. As I pulled into Lowe's it went into Active regen... the problem is that the egt went to 750 as I was turning the engine off. As soon as you put the truck in park, active regen turns off however the egt's were very high as they wanted to start their climb upwards. This unit has a turbo timer which I have set to shut the engine off at 350egt's. When I came out of the store 8 minutes later the motor was still running on the turbo timer so I had to push the brake to kill the motor only to start it up again. If I didn';t have this system, I would have driven it home one mile and it would have started Active regen again only to be shut off again. I truly believe that this is why so many people are having clogged DPF filters and egr/turbo problems. I having this system started the truck began to drive it and of course it went active again and I jumped on the freeway to drive through the active regen process. Is is a hassle, I would say so but again I truly believe that I won't have the sooting problem so many others are having or will have. Should we have to buy an 800$ system to keep the truck from dying, No... . I also believe that this truck was not made to drive around town as it will load up and cause it to do more regen's then one being driven up and down the freeway. Also believe that these trucks used for towing are keeping the egt's up by nature of their loads which is also keeping the DPF filter clean. The only time your overhead is going to chime is when it is paramount that you drive through a regen cyle. . God only knows when that will happen... Save your money and invest in the Edge Juice complete system... it is so worth the money for the turbo timer function, the code reader function, all of the alerts as well as the power boost function. Just my opinion as I love mine. . Sorry for the long post and hope this helps!
