Oh snap there might be a DPF Delete now :D

[ThatStinging_Jeep]

How bout start with green diesel tune? Always heard good stuff from them and won't require deletes. If I make up my mind to switch to diesel (my own reasons), I plan to go that route.

As long as GDE makes a tune and some sort of EGR i would be happy,but i would kinda like to delte the new ecodiesel cause used to have a Duramax that i had deleted and boy oh boy was the difference night and day dude,but i cant make up my mind

Yea, I'm all for the delete, but at the cost of warranty, the risk is still a tad high at this point. Seen pros and cons with the diesel, some of which could've just been user error. I'd like to hear more input on those with 30-60k miles... if any have driven that far yet of course. If we can get 60k roughly worry free miles, then a delete may not be "necessary". But if many are having emissions issues before then, then I would strongly look into it. But I think the gde tune will more than suffice for many... until truck needs to go in for warranty work. Just no winning with stealershits

So question,if your a person that owns a deleted diesel truck can you get fined? I wouldn't think so but can you?

The EPA has made light truck diesel modification a high priority target because it went unregulated for so long. Even in CA, diesels were exempt up to the point a PZEV gas engine could pass the sniffer with almost nothing coming out the tailpipe.

They are targeting shops and manufacturers more than people but they're using social media and the like to find out which shops are doing the work. People love to talk about their trucks and they're just handing them targets.

Alright now listen to me you little s#it......my bad ??
See the thing here is that I wanted the diesel engine because of its torque and fuel economy,2 it would outlast the gasser cause it's a diesel 3. If I can do a whole def/dpf and egr delete that would be awesome cause it would result in the motor being more efficient, run cooler if you could do a egr delete and of course make more POWAHH Babeh cause really.....who doesn't want more power and also you can get even more mpg's cause of what you done

Also if I can do a emissions delete theres less you gotta worry about cause of the additional sensors and all that fancy jazz and i could fab up a whole exhaust remove all that junk out and save weight and since I will actually use my truck and not leave it a pavement princess that could be in my benefit,but anyways not too come off as a dick dont say dumb close minded s#it it's like saying "if you dont wanna deal with catalytic converters dont get a gas engine"you also gotta think of what other people do/think :D

What an entitled little child. I’m frankly pretty surprised our economy finds someone with this kind of attitude valuable enough to reward the funds to be able to afford such an expensive vehicle.

Your right when it comes to other people,not for me though,I was just joking around though cause everyone has to have a little fun and If you like memes you will see that used this meme,ofcourse I added a little twist

So I’ve had the diesel for a few months now. Before getting it I was somewhat interested in a delete but realistic about there probably never being one. The main reason was engine longevity, and I did a bunch of research to see what might be coming down the pike, e.g. GDE, or what maintenance issues I needed to be ready for. There’s a lot of moral panic over these systems with varying levels of legitimacy. Actually there’s a lot of moral panic over everything and from every possible political angle. It’s fatiguing. But there are some reasonable technical concerns about whether particulates are the right focus and whether people are sacrificing their engines for it. There’s no denying that there’s a lot of expensive stuff to break on these things. Anyway, based on what I read while waiting for my truck to arrive, it seemed that life for eco-diesel owners is just a series of endless regens and boxes upon boxes of blue cow piss.

One of the first things I did to mine was put a scan gauge on it to monitor DPF and regens. I’ve noticed some things:

1. After almost 5000 miles, I’ve still got 1/2 tank of DEF left. I’ve read and listened to countless testimonies of folks getting 2500 miles on a tank of DEF. I’m not experiencing that at all.

2. I could count on one hand the number of times my truck has gone into regen.

What I’m experiencing is what people have said about diesels long before moderns ones came out. They like highway miles. This is the point where I have to reveal my privilege. I don’t commute in this thing at all because I work from home and because of where I live, paradoxically, I often have to get on the interstate for a good distance to go most places. It’s always been annoying, but now I like getting this thing out on the road and running it hard. I do very little short distance, low speed or stop and go driving.

I find that the DPF percentage often drops substantially just getting it up on the interstate without a regen and it makes sense. It might creep up to 50% and then drop down to 20% on a good drive. On the trail, the DPF percentage climbs precipitously which also makes sense but is a little concerning. I’ve had it go into regen twice while crawling up a Jeep trail. From a DPF perspective running it long and hard seems to keep it fairly cleaned out.

My take away from this is that this is not a great commuter vehicle unless your commute is really long at 70MPH. It’s not an around town vehicle either. I’m willing to put up with the emissions shenanigans on the trail because this is about only time my truck does regens.

For my usage, and given my experience, I’m lot more sanguine about all this stuff now. Obviously stuff is going to go wrong at some point and sensors, filters et al., are expensive. I’m just going to enjoy it for now and not let it worry me. Obviously for a lot of other drivers who use there vehicle differently your mileage may literally vary.

I also keep thinking about my last 2 Jeeps. My 2004 TJ went 120K miles without a single problem and I dogged that thing hard on and off road. My 2013 JK spent half of its time in the shop with what I am convinced was the fallout from a sand casting engine problem. Maybe my luck with Jeeps is like the Star Trek movie curse. Every other one is crap. Fingers crossed that I’m due for a good one.

I am happy to deal with a catalytic converter, as it reduces emissions. Likewise the aftertreatment system for a diesel engine reduces emissions. The DPF in particular keeps the black carbon from shooting out the tailpipe. I don’t want to return to the smog filled air from my childhood. …and I want to reduce the global temperature trend. Gaining a few HP for an individual versus the impact on the many is not worth it.

The rise in temperature is impacting the places we like to visit with our trucks, such as our National Parks. So, I repeat myself…. If you don’t want to deal with a DPF, don’t buy a Diesel engine.

I agree... pollution sucks. Black ass exhaust is ignorant. But this planet had been warming since last ice age for past 20,000 years as a fact, and will continue till the end of current cycle. Estimated in another 10,000 years or so. Then we will be in a global cooling situation, were northern cities will be scoured from existence from enormous glaciers. We maybe extinct as a specie by then. Modern Human 2.0.
So what I am getting at is, pollution sucks and no one has the right to spread it Willy nilly with out care to others and the environment. Read up on the major pollution makers, volcanos... one large eruption in a single day has the potential to produce as much gasses and particulates into the atmosphere as humans produce in a year. So us slowing down global warming? Along with China not letting up. We may slow the trend by a few days in the course of many thousands of years.

It's shame this thread devolved into a "my-facts vs your-facts" political bs. If I wanted to read that crap I would read the news.

Maybe a simple understanding of how the technology works.
1) EGR technology was developed for the gasoline engine. unburnt fuels recirculate to the intake and get burned. Applying this to the diesel recirculates unburn or partly burn fuels back to the intake that is more often than not in the form of soot. Carbonized soot. It provides no reduction in emissions and no benefit to longevity.
2) the soot that doesn't get rerouted to the EGR gets trapped in the Diesel exhaust filter until it builds up to the point flow and temps are restricted.
3) Regen, purposely retarding the timing to build hotter Exhaust temps in excess of 1600+ degrees to burn the exhaust filter clean and blow the re-burnt soot out the exhaust pipe at temps that can and have started fires.
4) Diesel Exhaust fluid is used to control Nox emissions by combine the DEF with the hot exhaust gas to reduce emissions.

So now we have an idea of the technology being applied... longevity in diesel engines is due to several things. 1) clean fuel, 2) clean air 3) Good maintenance 4) long run times.

-So why port carbonized soot back into the motor? it serves no purpose but to break down cylinder walls and rings. eventually passing into teh oil and bearings. no emission benefit. destructive to teh internal working of the engine.

- most folks don't drive a diesel correctly. No warm up, short runs and expect it to run like a 500HP gas engine. When they tow, they over load and ask it to maintain speed with little to no regard to exhaust gas temps and then wonder why the POS blew up a turbo or melted a valve or piston.

Like others I was hoping for some good information here.... maybe this will help understand what is going on in the diesel with respect to the "enviromental controls"

This is misleading at best and #1 is flat out wrong.

EGR technology was implemented on gas engines to reduce combustion chamber temperatures. Exhaust gas is largely inert so piping that that back into the combustion chamber reduces the available air to burn and reduces NOx emissions as that reaction only occurs over a certain temperature.

EGR serves the same purpose in a diesel engine only the higher combustion chamber temps make controlling NOx production much more difficult. Instead of controlling their production, manufacturers use DEF to fix the problem after combustion. EGR is most effective at idle while DEF is most effective at cruise/load - the two work in tandem.

The particulate filter is to prevent that soot from reaching the atmosphere directly. That soot is either dealt with passively with a catalyst or actively by heating the exhaust gasses to the point the particulate matter combusts. Regen is nothing more than the latter, burning off the particulate matter that has accumulated and a forced regen is only required if the vehicle is not driven within the required parameters to burn off the soot regularly. That should not be a problem with a daily driven vehicle for anyone where a diesel makes sense.

All of these things massively reduce the emissions of diesel engines.

The largest cost to longevity, as I've said many times here, is that most truck owners don't want a 5.9L Cummins 12v, they want the torque and performance with regular truck mannerisms. That means lighter components and more aluminum so what you have now is far from the tractor engines of old. There's no reason to build a 1M mile diesel engine like that 12v when the truck will fall apart around it in 20 years or when your new buyers are going to dump it before 100k.

There is no real need to delete any hardware on this application. The Gen 3 engine has a high pressure egr and also a low pressure egr. The new GDE tune coming out makes use of the low pressure egr the vast majority of operating time. The low pressure pulls exhaust from after the DPF, so there is no soot (PM) in it. This allows for good oxygen control along with cleaner engine oil and cleaner intake. The factory exhaust is also not a limiting factor for performance. The JL and JT perform amazing with the Green Diesel tune, the factory tuning is lackluster at best.

Excited to be able to actually buy the GDE tune. Hopefully the wait is nearly over !

And what are you going to do with all the batteries from the EV's??? No one has really adressed the issue of burying hundreds of thousands of batteries in landfills...

That's a bit of a straw man argument, no one in their right mind should be putting EV batteries in landfills with how much used LI-ion batteries are worth... The recovered Cobalt alone is worth a kings ransom.
Its like saying "think about all the lead acid batteries that end up in landfills"... no dealer/ repair shop would think to toss a lead acid anymore, when there is cash to be made recycling it. Unfortunately recycling pollution is a whole other problem that still needs sorting in some places...
