I appreciate the work you are doing to help with deletes and tunes sorry about all your issues with the JGC, but this drain and refill with 2 gal of def I cannot imagine this has any effect.
You could prove me wrong after driving 7000 miles since I never got a my first ever "exhaust system regen in progress keep driving" in my evic until 6478 miles. I took a pic while driving(spare me the lecture) to document it as I was on secondary road.

I want to do deletes using sims to fool computers and with out tuner as I do not need more hp,I do not want to leave any tell tails in case I have an issue occur and need service. I could reinstall egr,dpf,scr in a few hours if needed.

I have been all Diesel for 5yrs,to get away from ethanol mandated by aholes on capital hill. proven and known ethanol gas gets less mpg's and kills engines at 10%. The epa and the ahole and his cronies in charge on capital hill is going to up ethanol to 17% in near future. The same ahole made an agreement with Brazil to buy their ethanol and import it,while at the same time we subsides our farmers to grow corn for ethanol production. Our so smart government pays our farmers not to produce certain crops at all. Our farmers if aloud can grow enough crops to feed the world but we don't because it would flood the market,so people starve and that's ok with you?

To hell with feed starving people of the world,take care of the starving people of the USA first!!!

If you have a gas vehicle I would suggest you open the manual and see recommended fuel for max performance is HIGHTEST, strangely most high test gas in my part of the country has no ethanol!! Stations Here actually advertize that little fact!! Real oxymoron huh!

I had 2012 ram 2500 cummins with out def was in the shop 38 days the first 14 months of ownership for EPA CRAP ATTACHED TO IT got rid of it.

If you are on crusade to prosecute those of us who hate all the epa crap attached to our vehicles that are having/had problems because of this supposed installation environmental save the planet crap.

Then I suggest your quite your current job, if not EPA already and join the rest of the crusaders on capital hill and sing cumbaya that are in fact crippling the USA which already has the strictest standards in the world, as some on else mentioned 1 day of volcanic eruption taking place in Iceland currently and 1 day of Chinese pollution, each = more than 1 year of USA pollution. This does not count the remainder of the planet without any standards.
You can come back and complain after the rest of planet reaches our current standards before you even think about imposing more"good for planet improvements on USA and carbon foot print tax"

You go tell China they have to meet our current standards,or USA will embargo any China made products to USA and they must pay carbon tax and honor USA patient laws!! See how that goes for you!!

Better yet tell china no comply to epa standards all those promise note they are holding of USA are no good since they are holding like 91% of our countries debt.

I agree there need to be standards but give it a rest!

And yes I do my part in spite of not wanting or needing crap on my vehicles.

Sorry RANT OVER!!

From my perspective, it is trolling to come into one of these threads and attempt to hijack the discussion by white knighting for the environment.

Was anyone here *not* aware that the DPF and DEF/SCR are emissions reduction equipment? Anyone? <sound of crickets>

Maybe we should just stop feeding the troll, ignore him, and return to this very interesting topic.

I'll go: why is it necessary to empty completely and add the 2 gallons of DEF back? I have speculated a few possible explanations, but I would love to hear the answer.

Re: How to delete DEF injection with no software/hardware

EPA measures where they are engineered and implemented well do make sense (we need to be better stewards for the only home we have). OTOH with a high failure rate of DEF and DPF systems the engineering and testing phase of a new product has been poorly implemented. Thus as owners of these vehicles who want a reliable brand new vehicle, we should have the right to defeat these systems (not to pollute more) but to increase the reliability of a brand new vehicle we bought. Therefore, I think an exception should be allowed for defeat devices solely for reliability purposes that can be done by vehicle owners (or the reseller) who can prove (i.e. shop bills, service records of repeated emissions related problems) it. Now how to enforce / police this I don't know. And the proof is the vast majority of the reliability issues on the WK CRD (I used to own one - clogged DPF by 110k) and WK2 Ecodiesel (only problem thus far was a broken injector from splashing through a puddle on the highway) is almost entirely related to the emissions equipment (the WK's had major EGR problems).

Re: How to delete DEF injection with no software/hardware

As can be seen, there is a lot of angst here. These Libtard EPA zealots are brainwashed educated morons...just more of the same lefty idealist like those brilliant idiots in charge at the moment. If you want to promote radical environmental policies, go hang with the other morons and stay out of this thread. We didn't drink the coolaid and aren't interested in your advise.

Now, back to the discussion on how to make this $50k vehicle reliable.

The EPA estimates that the emission standards will prevent 8,300 premature deaths, more than 9,500 hospitalizations and 1.5 million work days lost due to illness, saving approximately $70.3 billion by 2030.

SCR is a so-called "aftertreatment" technology, which means that it destroys harmful emissions after combustion. This gives manufacturers greater scope to tune engines to improve fuel efficiency and increase power. Owners of SCR vehicles enjoy greater reliability and longer oil change intervals, which add up to impressive operating cost savings over the life of the vehicle."

Defeating DEF injection is just plain wrong.
Climate and Environmental fear-mongering is the prostitution of science in the service of liberal ideology. The EPA is an insidious cancer on our economy and liberties. There is no place on this forum for whining preaching libturds. BTW, Liberal has become a perversion of the word Liberty. Go away Troll and take your EPA propaganda BS with you!

And what further baffles me is that this doesn't only touch the SCR and DEF injection, but also doesn't cause the NOX sensor downstream to flag (and as far as some of us experienced, it doesn't take much in NOX increase to get the vehicle go haywire).

Re: How to delete DEF injection with no software/hardware

I am not 100% sure why it works... just sharing an observation I made.... and using resistors and other tricks to shut it off? Have fun. A stock tune with software edits will be way easier.

How many miles have you and your buddy put on each of your vehicles since you did this drain and fill with 2 gal ?

Is it possible you just have not driven enough yet to trigger regen cycle?

My first ever regen did not happen until 6478 miles ! truth!!

The only code so far mine has throw is " P20E9 Reductant pressure to high." knock wood!

This was fixed by reflash mentioned by willix in another thread.

Your jeep most likely has regenerated the DPF many many times and you never knew it.

Lack of the SCR (DEF injection) system will not likely cause the DPF to regenerate.
