IN DEPTH Detail of REGEN - 3.0 Duramax Diesel - exhaust regeneration

[@bankspower]

Another amazing video. Thanks for sharing this iDash feature set. Regen activity can be displayed for not just GM 3.0L DMAX trucks but for almost all modern full-size diesel pickups.

[@duncanharriman2324]

Do you just need one gauge to monitor this ?

[@hammer-r]

I use the banks gage to let me know when I’m close to or in a regen and if I can I’ll extend my driving until it’s done. I hate to interrupt a Regen.

[@4961Studebaker]

Good demo and explanation for those new to the 3.0. I left for a trip at 74 regen load, happened to be towing a small enclosed trailer and watched the regen number go down as the engine was working more with the trailer. Believe EGT 3 was around 7-750 couple hundred degrees above what I normally run. Number dropped to 54 then gradually rose to 100

[@mr.yamaha2855]

Great video I am goin to see If I can figure out when mine is in regen. I like the huge antlers in the Ford beside you at 12:45.

[@FrogPondBrewery1]

Awesome explanation of what is happening during a Regen. Thank you

[@DemonWorks]

Glad it was helpful!

[@NMTRUCKER]

My LZ0 regens between 300 to 600 miles and at highway speeds it takes about 12 minutes with EGT 3 temperature about 1150 degrees. I need to update my IDASH firmware to monitor the soot load %. Nice review.

[@BC_Hunter]

Would love if you could do a proper engine break in on a new LZ0 3.0 Diesel. Picking my new one up in the coming months.

[@R3lyc]

Takes my 2021 3500 about 50-70 km and about 30-45 minutes on the highway to complete a regen cycle. The regen trigger will usually hit 100 at about 50-60% soot load on the highway and 100% SL in city driving conditions. The fact that I can use the banks to manually regen on the highway has been a game changer. If I’m around 75% or more I’ll trigger the regen about an hour before the city, then I have a clean system to rip around town in. If I’m just city driving and I need a regen at least I’ll know when it’s due for a highway drive, but if things work out where I can’t do that it does have a stationary regen option too, but it only allows it after 90%. From what I know if this method, stationary regens are hard on the system, and some recommend an oil change after doing a stationary regen. That said I’d personally try to avoid stationary regens but it’s nice to know it’s an option that’s available if I need it.

[@rockymountainjazzfan1822]

You illustrate why modern diesel emission systems SUCK if you are doing mostly city driving. Also, during a regen, shifting the transmission into neutral or park will cause the regen to cease on most light duty diesel pickups. An actual hazard is if the DPF reaches full and it is impossible to drive to regen--I've seen that happen when, for example, a truck is stopped in blizzard conditions and driving the vehicle to conduct a regen is impossible. Ford anticipated this in diesel work trucks--with an option available in certain models for the driver to initiate a stationary regen if when the DPF level reached 100% and the vehicle can not be driven to conduct the regen. In those, the engine (with the transmission in Park) would rev to around 1700-2100 RPM and do the regen, usually taking 10-18 minutes (and a more than a gallon of fuel), but it could save being stranded somewhere with a full DPF and no way to drive it. Supposedly, this feature is built into 6.6 GM Duramax trucks, but can only be activated on trucks sold into commercial fleets. Some scan tools (will the Banks system do this, too?) will also initiate a forced stationary regen, and that is likely the only way to do it on the 3.0 Duramax. I would not buy a 2007+ MY diesel pickup if most of my driving was city/suburban driving--it's just asking for eventual (and expensive) emission system issues.

[@nick-cb6dl]

In my truck I limit the idle time unless it’s really cold and I want to get into a warm truck. Another thing I do is if I am idling I rev the engine about 1500rpms. Also during a Regin if I’m driving in the city I drop it down a few gears and keep the engine running at higher rpms to keep it running hotter. Not really sure if your supposed to be doing what I do but it’s the stuff I do in a big truck at work, limit idle, if idling I high idle

[@rockymountainjazzfan1822]

As far as I know, the 3.0 Duramax has no capability of manually putting the vehicle into elevated idle. Some 6.6 Duramax pickups could do with a modification that would allow one to use the cruise control function with the transmission in Park to elevate the idle. Some Ford diesels could do it with circuit modifications that would enable optional upfitter switches to elevate the idle. My 2012 Ford Super Duty with the 6.7 Powerstroke was modified that way, and it worked well.

[@CrustyAbsconder]

I am 100% certain that the average adult in the USA, can not comprehend anything about regen.

[@bighitstepside]

Lots of car guys too (especially boomers) have no idea what anything diesel emissions actually does 😂

[@kirkketelsen7695]

Are you sure that the fuel is injected on the exhaust stroke. I thought there was a 7th injector injecting into the DPF. Reason I'm asking is the the turbo temp is fairly low. I had a Ram 3.0 diesel and that motor did inject fuel into the last 2 cylinders and my turbo temps very high when regening. My Temps on regen on my LM2 are low like yours.

[@DemonWorks]

100% certain - GM Tech here.

[@TheMacronical]

If you're having excessive regens (for whatever reason), try the DPF catalyst from Pittsburgh Power. Ran some through my boss's LM2 the other day & it's worked wonders. It brings the exhaust temp needed for regen down by 300F, which would help the truck regen more passively. still need to solve the lubricity issues of ULSD elsewhere though, this has no lubricity additive in it

[@Mjhggdwww]

Is EDT hot shot enough to not have any of these issues later on?

[@em2760]

I’ve been doing an experiment with hot shots winter edt and regular edt and while they say it adds lubricity my regen intervals are very short using it vs not using it.

[@M379-m1s]

You can tell if you are in a regen without the Banks idash by taking your foot of the pedal and if the instant fuel mileage goes to 99 mpg you are not in a regen. If it shows anything else like 45 or 60mpg you’re in a regen. I’ve tested this many times and it’s accurate.

[@christopherperrone2153]

Not true

[@M379-m1s]

Yes it is true but sometimes when you’re driving slow it doesn’t easily jump back to 99mpg when you take your foot off the pedal. Occasionally you have to try it several times. I have a banks iDash and every time it’s in regen, the mpgs will NOT jump to 99 if I take my foot off the pedal.

[@PaulandCathyKohler]

Cool info. Thanks. I found this video because of a weird situation that happened at a stop light and thought a regen caused it. I got a reduced acceleration warning and please restart the truck even though it was running. Now the check engine light is on. I have a 2024 AT4 1500 with the same engine.

[@mzrzfxr]

I need to get a banks pod, but even without I notice in a regen the mpg drop about 2-4mpg, idle increase ~200rpm and the smell if I’m stationary. Smell is kinda bad frankly if I’m stopped with windows down, my wife says it’s a sweet burning plastic smell, yeah kinda is I guess 😂 I’m at a regen every 200-300 ish miles, still fairly new. Mixed driving but a decent part of my commute is flowing highway (~70mph) so it gets nice and hot during the drive regularly. I also usually disable start stop, cannot imagine it’s good for the engine and emissions. Best I can tell I save maybe 1mpg tops in stop n go with start/stop enabled…

[@adamf468]

I'm confused. I was under the belief that the 3.0 Duramax has a SCRF that combines the DPF and SCR into one unit. It's a passive system that burns off emissions crud unobtrusively to the driver. There is no active regen cycle for this engine and there is no dash indicator for that reason. Also your banks unit only works for the LML and L5P engines to my understanding which are the bigger diesels that use active Regen and have DPFs. What this means is you don't have to worry about Regen in the 3.0 Duramax to my understanding, nor drive any extra mileage.

[@DemonWorks]

I appreciate your insight on this, however the 3.0 definitely has an active regen, as shown in the video. There is also a passive regen which seems to be extremely rare to activate. The Banks idash also for sure works, as shown and also on their website shows it for the 3.0.

Hopefully never, it’s programmed to only alert if there is an issue. I monitor mine through the banks iDash. In a factory setup, you will only know it’s in regen based on the things I talked about in this video with idle, smell and mileage.

[@johnmeeboer8971]

can you turn on the regen manually if you are going on a long trip

[@DemonWorks]

only on the early models.

[@rodgerb962]

Have you noticed the noise that your last truck was making? I took mine in and they said it was a actuator in the EGR making the noise and changed it out. My fuel mileage dropped 3 to 5 mpg after. Took it back 3 times no answers said nothing was wrong and the noise was still there. Basically told take a hike. Keep ‘‘em coming enjoying your video’s.

[@cje26]

Did you scan for codes? My LM2 has been making a similar noise for quite a while but I've never had a check engine light or any hidden codes, so I'm just letting it ride. It all started around the time my local stations switched to winter blend fuel, so I'm hoping that's all it is.

[@4961Studebaker]

New LZ0 will use more DEF but that’s a small consolation prize if some increases HP/TQ is what you want. I’m in the camp if the LM2 isn’t broke stick with it. Unless you want the new interior a new truck provides you’ll be choosing the vehicle for more attributes than just the engine.

Seems like unnecessary stress to worry about regen. Of 35k miles on my lm2 never had a warning light or CEL regarding it. If I did monitor it I couldn’t see myself going out of my way to continue driving to let it finish under any circumstances. I’d be curious to know the cost of a replacement exhaust and what the average life of the particulate filter is.

[@Vacationland019]

Lots of unnecessary stress. 41k on my 2021 i bought new in 2021 is been nothing but perfect. Regen on these isn’t as big of an issue as the older trucks.

[@daniejw]

How does Soot Load # differ from Regen Trigger # ?

[@1randyharbin]

Soot load is just the DPF soot load, the regen trigger accounts for DPF soot load and all the other factors the ECM takes into account to determine when a regen will occur, usually the regen trigger will equal or be 1-2 points above soot load, but for instance on a long road trip soot load could be reduced by passive regen but the regen trigger will still stay higher as miles and gallons of fuel used continues to increase.

[@DemonWorks]

Soot load is a measurement from the pressure sensor on how much calculated soot there is. Could go well beyond 100%. The regen % is the calculations from all of the sensors and fuel consumption with miles driven to calculate when a regen should take place.

[@jimhebert4261]

Is it possible to list all the parameters that are shown on the top Banks display? Thinking of getting one for my Duramax and this would help tremendously to know when it is in Regen. TIA Jim

You can select your exact vehicle then add the items you want to your cart. The supergauge is the lower gauge and the top is a datamonster. They are the same gauge but the datamonster is able to record data on a memory card for playback later. I would suggest a supergauge and stealth mount to most people.

Get 1 is just off the turbo, that needs to be monitored when towing. Egt3 is at the exhaust filter, that should go to 1000 when in regen.

Exhaust gas temps stayed 700 or lower during trip. Had a 2 day stretch with temps back to above 30 and noticed the soot load rise normally. Wonder why freezing temps lowered my soot load without a active regen?

[@HerrimanB14]

i had a similar experience, ran about 75 miles in -16F and mine dropped from 60ish percent down to 31 percent. I couldnt come up with an explanation that made sense, it would be a stretch, but im wondering if it has something to do with DEF being frozen and the truck using the exhaust brake to keep more heat in the exhaust?

[@kerlyb123]

@@HerrimanB14 IMO, I just think iDash SL monitoring is not totally accurate. Seen it go as high as 104% for many miles before regen kicks on. Seen it go from 30-40% to 99% in an instant and then regen kicks on. Seen regen cycle off with still 28% SL on iDash and exhaust temps have normalized but the SL continues to very slowly diminish to 0% over next 20-30 miles of driving.

On the i-Dash you can set a field to show gallons per hour of fuel usage at a given load/speed. Once the regen starts you can see the increase GPH rise. After you get a feel for what's "typical" you can get a good estimate on the additional fuel burned to accomplish the regen process.

It is not unheard of to have some infant mortality of components in a brand new truck, usually something to do with the emissions systems with the diesels, but other things can cause problems too.

[@gunsho11b]

They should have an idle or "parked regen" option that is standard on these vehicles that the driver can activate in the event that the DPF is full and you are not able to continue driving . A perfect example would be you are caught in a blizzard and stranded on the side of the road. Its -20F outside and you have to keep the engine running to stay warm. Or say someone lives in NYC and does nothing but stop and go driving and short trips, but they want a diesel truck just because. I know some of the heavy duty Ford's have a "parked regen" option. With all the fancy display's on these trucks there is no reason why GM cannot incorporate this on the 3.0 duramax along with all their other diesel engine options. From the smallest of diesel cars to the large semi trucks, every modern diesel vehicle should have a "parked regen" option.

[@DemonWorks]

It was probably some kind of safety reasoning. I can see someone doing a regen in a garage...

[@jasonwoody8041]

The problem with "parked regen" at least in semi trucks is your twmps dont get as hot and you dont get a complete burn. So the more you do it the less complete you clean. Think of it as a old rechargable battery. Where every charge you get further from 100% i work for a supplier to the big 3. And my semi does not see highway use. The dpf filter needs to be replaced about every 16 months at the cost of $18,000. All we can do is a parked regen. While in a pinch like the situation you gave it would be nice. Im willing to bet a lot of people would do parked regens as the main option.
