DPF delete question

[Phillirdwn]

19k miles on my 2024 2500 and got the “service dpf system see dealer”. Cruised at 2500rpm in 5th gear to burn it out and it went away after about 5 mins. I knew the def system woud screw me at some point but didn’t figure it’d be this early. Are there any true cons doing a delete besides voiding the warranty?

You mean other then having to spend a lot of $$$$ for a new ECU & then the programs that need to buy and install along with the cost to carefully remove the extra weight along with voiding any warranty you have, how about just drive the truck more often on the hwy along with less stop & go city driving, you may also want to try using a fuel additive from Pittsburgh Power Max Mileage FBC or Archoil 6400D an 6500 to see if its helps as it has for many but not all.

It’s illegal.

My 2019 HO/Aisin/4.10 would do 24 hour regens like clockwork. In the almost 70K miles I owned it it never did a soot based regen. Yes, I kept track. On the other hand, my 2024 HO/Aisin/4.10, same drive cycle, same roads, same fuel sources started out reaching the 24 hour mark but would build soot % on the gauge, and very seldom reduces the % by passive regen. Over time it now regularly does soot based regens, lately as early as 12 hours, and it is pizzing me off. My idle percentage is LESS than 4%, and I regulary drive my "de-soot" route that worked for my 2019 like clockwork. I have even extended that route, and tried increased speeds to no avail. I have tried Archoil, and the new Power Service magic snake oils, no change.

I have not deleted, but I can certainly see the attraction. Having to change the $$$ ECU, and relying on foreign tuners with questionable support are a real problem.

DEF is not going away. And it’s not as troublesome to everyone as a few malcontents imply. My ‘24 Ram 2500 barely uses DEF and has given no troubles.

yet.

@ 8: mins you will learn DEF increases mpg and power output. Yep. True. (because engine mfr’s castrated engine-power to previously meet EPA req’s….. so DEF cured that issue. It’s a tail-chasing-dog thing.)
Enjoy the video, this guy’s funny. (accurate, but funny)

DEF only reduces NOX emissions at the tailpipe. No way it can do anything for mileage.

That comment suggests ignorance of the subject. It allows better tuning for engine output.

 

[tjfdesmo]

To meet NOx standards without DEF it was HEAVY EGR, and retarded timing. Fuel dilution was a big problem. When SCR was added they could reduce EGR substantially, and add some timing again. It did allow better tunes, and more HP while meeting NOx standards.

Right back at ya.
Emission control devices only have one purpose. That is to enable manufacturers to comply with ever increasing stringent EPA emissions requirements. They have nothing to do with “tuning” for HP or mileage gains. It’s all about what comes out the tailpipe. Nothing more, nothing less. SMH

It’s illegal.

Yea, so?

Our own government even knows this emissions crap is…well, crap. Hence why they outfit their own vehicles without it.

You can laugh all you want. It's true the intention is NOx reduction, BUT the benefits are less EGR and more timing. Fact. I'd rather have a full delete, but SCR>EGR all day long.

That is False.

It’s not nice to repeat or spread falsehood.

Other than some military vehicles intended for combat, gov’t vehicles must comply with EPA rules.

His original statement holds, the manufacturers are not capable of getting the HP/emissions numbers and be legal without using the SCR system to their advantage. If auto manufacturers could get the right HP/emissions numbers without adding a bunch of expensive parts they would.

You 100% have the right to be wrong, and you are. Happy trails to you. SMH LOLOLOLOL

Dang... Faecesbook is in full swing today.

Back to the original post/comment/question, I agree that driving the truck more at highway speeds (especially while towing if possible) is a simple way to "work" the truck and help keep the emissions stuff cleaner. Some have recommended using Archoil 6400 as a cleaner and 6300 for anti-gel purposes, but Archoil does not recommend mixing any fuel additives (even their own) with other (even their own) additives. This information came directly from Archoil.com Customer Service via e-mail today.

I mention this because I am currently in the process of burning off the 31 gallons of fuel treated with my last dose of Amsoil Cold Flow before using the cleaner. Before I add any of their 6300/6500, I will run the 6400 through the system, then refill the tank with fresh fuel and their 6300 or 6500 as appropriate.

One thing I have done for a couple of years is to build and maintain a spreadsheet showing date, mileage and total engine hours (my idle hours are <15% of total engine hours), with columns for mileage and hours since previous regeneration. This shows trends... I have ranged between 9 and 24 hours, and with varying mileages. Yeah, I know I am a bit of a geek.

EPA is a common bogeyman to blame…but here’s a truly accurate explanation of the relationship between Law, EPA, and emissions enforcement: (bottom line, EPA cannot get rid of , and it is a Federal offense to delete, EGR, DEF, or DPF):

Yea, so?

That claim is patently FALSE.

Deep in the Nevada desert on a dirt road from hell, my truck wanted to do a regen on a road I was lucky to get to 20mph on.

I went in the day before a delete and had the truck measured out the tailpipe for gases. The day after delete I had the truck again measured at the tailpipe by same state inspection place. I was now 2ppm cleaner than stock. No big deal and cost some dollars!

But I no longer had the same truck. My gas mileage went up 2 to 4 mpg. The power was hard to control and not spin the tires at lights. It was so much faster and powerful. Towing my heavy boat became a joy and I could pass people with ease going uphill. I no longer had to look for def when fueling up. I found it a pain, maybe you don’t. And best of all, I am never in the middle of the desert being told to go faster when it is not wise to do so!

Deleted at 27,000 miles, 266,000 miles now! You can say all you want, either way. But this story is fact!

Freedomworx does point out emergency responders may be deleted. You don't want a de-rate in an ambulance while rushing a critical patient.

I imagine LEOs wouldn't want this either in the very few that might be diesels (SWAT response vehicles, maybe?)

 

[Grams]

Emergency vehicles generally meet EPA emissions standards… but may be exempt from “limp mode” requirements.
