DEF system removal.

[azjl#3]

Thanks everyone for your replies. Not trolling. Just ignorant of the law, but have no intention of acting on any of this. An employee of the dealer I bought mine from recommended it, but I was suspicious of his suggestion. Looks like my suspicion served me well.

Bad idea, besides illegal.

Your attempt at saving pennies will incur thousands trying to tune and maintain. Try taking it to a dealer, they will deny service.

There are places in the country that have no emissions requirements, however, they require vehicles to be dot, epa compliant, even if they don't actively enforce...

Pretty sure you can start a regen with JScan.

Really?? Do you know where in the menu that would be? I have a JScan and am very interested in this if true.

Just found it! Wow that's incredibly helpful thank you so much.

Obviously you’re asking to remove it so you can clean it and then reinstall he next day, obviously. Mostly squares here man, shadows are terrifying and we all support the thing.

Removal of the DEF system is 100% illegal if you are going to drive it on the US roadways. Its a federal EPA violation. The issue though is getting caught. If you live in a state that has a vehicle emissions program you will likely get caught. Outside of those areas you probably won't get caught unless you are excessively rolling coal. There have been too many major fines being levied towards companies that knowingly sell a system to a person to delete the system. You might be able to find a company in Canada to do the deed.

Right! Who needs this kind of headache for “I get 2 mpg better than you do”.

Just be thankful that you don't have a tier 3 diesel like a Kubota tractor. Every so often you have to crank up the rpms to burn off the particulars that collect in the clean exhaust system. DEF is just an additive to bypass this burn off process. All of this is to help keep our air cleaner. Not a bad thing....after all its our only Earth. I would not try and bypass the system.

I will not comment on the DEF things since others have already corrected it. However, I will comment on the DEF system help keep our air cleaner. While it does help reduce NOx, it is not an issue unless you live in a heavily populated area like Las Angeles or New York City. In less populated areas where people are spread out over a larger area(over 95% of US land mass) and the NOx has time to dissipate into the upper atmosphere where it is good for the environment since it is a ozone gas, it is not an issue.

However, due to the EPA's one size fits all policies, those who live outside of these areas also have to have emissions equipment. So even though your tractor will likely never be in an area like this, you have to have this equipment just so people can continue to have the amenities of city living. I will also point out that tons of NOx is made naturally with every lightning strike and forest fires.

EPA this, EPA that .... EPA can hold my nuts.

Just because alphabet boys say it's illegal, does not make it such. Administrative agencies and bureaucracies do not have the power to create law on their own. Do not cower to nor live in fear of said fools.

As with all things, use your judgement. I digress.

They will. Pretty sure they held this guys quite firmly.

That's fine. I'd give 'em more than they bargained for.

Delete all emissions. Back in the day we had muscle cars that made big power. Now there's nothing that makes that kind of power due to emissions. Same for diesels, back in the day they made big power. Today, they make barely anything. Plus mileage is garbage. So, take all of that stuff off.

Same for leaded gas. Nowadays we burn valves because the lead cushioned the seats. Never a burned valve back then but for today, it's a real problem. Then don't get me started on detergent oil or low sulfur diesel.

The only impact it will have is by reducing systemic complexity from a maintenance point of view. From a MPG point of view it will have no impact to negative impact - in that you will always have a CEL and probably limp mode unless you change the programming... If you do that, the benefit you will get will be solely from the tune, and there are good tunes from companies like Green Diesel Engineering which will still use the DEF and emissions system, and provide better benefit than removing the system. You're better off just doing that than you are removing the DEF system.

Do you have a resource for the benefits of a tune ? I'm not interested in a delete, atleast not at this point. But the idea of getting better performance from a vehicle that I am already very happy with, sounds solid.

Interesting interview with Gale Banks here. Ignore the title as I never heard him say he makes more power with a DPF installed. But he does say that when he tunes deleted diesels, the record holders do not make smoke, perhaps meaning that he thinks a properly tuned diesel may not need a DPF.

Just thinking... wow some folks here must squeak when they walk with such tight asses... ha ha

What muscle cars back in the day made more power than today's muscle cars?

Note, of course, that manufacturers started using SAE net horsepower ratings instead of gross in '72. They were all overstated by about 30% prior to that change.
