Generic DPF filter delete.

[L47TLBwannabe]

I was referring to the pressure differential switch that Eric was talking about. My Kioti dealer told me that you can unplug this switch from the two balance tubes if you have a DPF issue where it keeps plugging up. The tractor will keep running like there is nothing wrong, the CEL light will not come on, the tractor will not go into limp mode and the automatic regen cycle will not work.

And where is this switch located? lol

On top of the DPF connected to the two exhaust balance tubes.

Are there any long term consequences to doing this?

Not sure. They did say that you could still run the manual regen if needed. My DPF was constantly plugging up due to a bad fuel injector spewing 50% more fuel. This was mentioned so that I could use my tractor to get some needed work done before returning it again to be fixed. Unfortunately it went into limp mode before I had a chance to do it. I never had a chance to try it. You would also have to put two hoses on the two pipes and plug them or risk burning the paint on your hood.

Well its something for me to keep in mind in case it does malfunction so far my CK3510 has done one regen and will probably do another in the near future. I got a quote from an outfit that does delete's as they aren't illegal in Canada and it would cost around $2,000 CAD to get done.

IMHO it would be well worth it once the tractor is out of warranty.

Yeah I wholeheartedly agree!

The tractor will keep running like there is nothing wrong, the CEL light will not come on, the tractor will not go into limp mode and the automatic regen cycle will not work.

That pressure differential switch is the primary control that tells the ECU to do a regeneration cycle I'm surprised to hear that we can run our tractors without it plugged in without the ECU timing out and kicking into limp-mode. Either way, the DPF would eventually plug up limiting power to the point where the tractor wouldn't make power. That said, with the plasma table expected to come in next April, my Tinker-Time will be spent trying to learn the software and immediately making some of the upgrades I hand made for my tractor like the steering cylinder guards, the skid-plate out of heavier material, a insert for the brush guard that works with the headlights, and some other stuff before I turn my attention toward a DPF delete kit.

That said, since it is winter right now, one thing I do suggest to anybody who runs their tractor in lower than freezing temperatures and is experiencing frequent regenerations cycles as a result of their tractor never warming up, is to swap out their thermostat for a warmer T-stat. Running too cold and having regeneration cycle problems was a real problem for the first few years of Tier IV engines and their field repair in fleets was to pop in warmer T-stats. In our case with the NX tractors (and l suspect any Kioti tractors that take the same part number T-stat as our NX tractors) a Stant 48808 is a drop-in replacement. Do not worry that the bypass is a little longer and stronger than stock as the T-stat works great even in high 90 degree temps here in Minnesota. Don't reuse the existing stock T-stat gasket, it'll leak even with RTV, so make a new one or get a new one.

My only comment besides your music on your video's suck Eric is... Don't ever plan on trading it in or selling it because once you do that it's yours forever. Reason I say that is if you tamper with the emissions system and sell it or trade it without reverting all the components back to the OEM state, you are 100% liable for any and all emissions repairs whether you own it or not. How it works bub.

Smoke that...

Because you're a lawyer, right? Just like all those Chevies, GMCs, Fords, Dodges, Kenworth, Peterbilts, et Cetra trucks have never been sold after adding a DPF delete.

You have little to contribute, but I get it and have seen people like yourself my whole life: you're just there to be a hindrance, making small-minded, resentful remarks to those of us who puzzle out problems and create. I already know your spirit and it would be better if you wouldn't say a thing and remain silent. Not. A. Word.

Thank you!

No butthead (Minnesota Eric), because it's Federal Law. It's actually a felony to alter emissions systems and likewise on cars and trucks if the vehicle won't pass an emissions test because it's modified, the original owner who did the modifications that render the emissions hardware / software not operable is still on the hook for necessary repairs to make the vehicle pass. But you aren't stupid, you already know that but chose to ignore it which, is you choice entirely.

Don't play ignorant. It's not becoming of a person of your 'intel level'. But, then, maybe it is considering your video's.....

I don't care what anyone does, you do own it (tractor or motor vehicle), just be aware that your actions can be used against you for compensation down the road if you ever sell it and the next owner has to have it certified or needs service at ANY dealer. Franchised tractor dealers will not knowingly work on an emissions modified unit when the repair consists of emissions components.

Why any 'chip' seller for a car or pickup or whatever states you need to pull that chip and restore the ECM to the original settings BEFORE taking it in for service at an authorized dealer.

of course people disregard that, but then most people don't bother reading instructions anyway in as much as we live in a 'plug and play' society today.

That fine print will burn you every time.

I'm done with this thread. Do what you want but just be apprised of the ramifications down the road...

Why I don't own and never will own a post 4 diesel tractor. Both mine are pre 4 and how I like it.

Thank you!

As to you, I didn't do anything but state the facts. You chose your own path, I think (maybe wrong) that you are an adult. You make your own bed, you get to sleep in it and, I'm quite comfortable in mine....:drink:

 

[ptsg]

Let's face it... What other answer did you expect? Every single emissions related thread, either Kubota or Non Kubota, you come out of nowhere with the same old post saying that you don't have nor want a Tier 4 tractor without any contribute whatsoever to the threads in hand and you actually scare people to stay away of them for some reason, even though you haven't dealt with any of that on tractors.

I'm pretty sure Eric is aware of all the legal bureaucracies related to messing with Emission systems.

As far as I know, there is no inspections on off road vehicles in the US, so I don't think there is a problem. And if they do start something alike, it can fire both ways. Either Eric will have problems for messing with the DPF or you may have to upgrade the tractors to the tier 4 stuff, like California does with the trucks.

If it is a simple as unplugging the balance sensor then why couldn’t you unplug it and replace the dpf with a straight pipe? I sure wouldn’t unplug it just to bypass the auto regen, besides with out the pressure switch you wouldn’t know when it would need a manual regen. As Eric has said you’ll just end up plugging up the dpf and cause more issues.

 

[sd455dan]

interesting thread.

Yeah Doesn't look to be as easy as unplugging a sensor


Just a guess but looks like somebody got creative with an arduino project, looking at the DPF emulators on ebay.


Young person built this arduino project which emulates a diesel engine that utilizes/controls regen on a functional DPF

If Kioti employs competent software engineers, the control system will recognize that back pressure isn’t increasing during operation as it should be as soot accumulates in the DPF.

Lack of a signal from the back pressure sensor would lead to the generation of a fault code, and eventually put the engine in limp home mode.

Not sure of the competency of their software engineers or calibrator, though.

Lack of this software would be a serious problem if the EPA or Carb discovers it, and would lead to penalties and emissions recalls.

Several automotive and truck dealerships and repair shops have been fined and have signed consent decrees over removing emission control equipment. The crackdown started in Ernest last October when several “tuners” were effectively put out of business. Most Heavy duty truck dealerships will not work on a truck that has been tampered with. It’s only a matter of time before the message gets to it Tractor dealers.

Oh man, so well said.

As for the "unplugging the sensor". .... can some one just try it and verify that the ECU doesn't hit a limp mode? You wouldn't want to leave your OE DPF in this state for too long, because regens are NECESSARY, and a good thing to clear out the soot. But after a regen (or after a manually initiated one), you could unplug the sensor for at least 40 or 50 hours without worry, I'd think. If no codes, derates, limp mode, then we'll know we can just straight-pipe the dang things.

However I will also say this: DPFs are a good thing. They hold the carcinogenic, deadly particulate emission until it can be burned away much more cleanly. If one experiences frequent and recurring or expensive issues with a DPF system, I would never judge them for deleting it. But I can't encourage anyone with a perfectly functioning emissions system to intentionally modify it this way "just in case" it has problems down the road. Simply wait until it does, and heck, hopefully it never will! In the meantime by keeping the DPF intact, you will be exposing yourself, your loved ones on your property, and the world's atmosphere with less poisonous garbage. I am looking forward to upgrading to a tier 4 machine in the next few years, partially just to breathe cleaner air while I'm out tractoring around. Plus, the tier 4 engines are much quieter running, which is also a nice benefit!

 

[JimR]

Just thinking out loud here; but it makes me wonder if you could just drill out the particulate filter and run it like a straight through pipe, leaving the differential pressure sensor in place. it would never sense a differential pressure and therefore should not trigger a regen.

I see no reason why you couldn't do this.

 

[JimR]

Why go through all that? Does it cause you that much grief for a simple regen on a tractor?

To answer your question, YES it does when Kioti refuses to pay in full the warranty costs of fixing a tractor that is under warranty and it costs the customer over $1500.00 to have his tractor fixed for failed emissions. I have the bills to prove this. The posts are up on this forum of my issues with Kioti.
