If the common person had to handle that crappy def solution I think it would be banned. Its smells terrible and if you spill it on your paint job it starts to fade the paint. I am not 100% sure but I thought I heard that stuff causes cancer. Is that true. I do keep my def tank a quarter full for good looks.

I'm certain it's known to the state of California to cause cancer.

I think if DEF were cancer causing, our own urine would have killed us long ago. The stress and anger required to keeping DEF systems working, on the other hand, certainly will kill us.
In Roman times urine was collected from all the public bathrooms and the urea concentrated and used to make ammonia for washing clothes.

After having my delete redone , my truck feels like it got a new lease on life. I would advise anyone to be careful who you buy delete software from. Alot of it is actually knock offs just like rolex watches or a like. My first delete was one of those and the guy who did it does not take responsibility for the mistake. Cost me 4000 the second time but at least I have a good truck now.
One question I have, If we buy the software from a mechanic, shouldnt we own the computer program we bought and store it in our offices. If something happened to my ecm and had to replace it, wouldnt you need that same software again.

I heard a rumor about a guy that knows someone who heard of a guy that did deletes to never let anyone update engine software post delete as it would restore all emissions settings. He would come back and reflash it once but after that you'd pay again.
I don't know if it's true or not.

From what I’ve heard it would depend how good a customer you are. John Deere is the worse culprit for updating engine software while techs are working on the machine.

Was reading in a trucking magazine that the port of Vancouver is going to restrict access to only newer trucks, I think 2006 , and moving up every year. The unions and trucking associations are fighting back. Likely some government incentives for the port to do this. Eventually emissions testing will be part of the safety. Old stuff will eventually get phased out as stuff like this happens. It will work it’s way into ag, I can guarantee that. Like I’ve said before, government no longer needs to enforce the laws it makes, just needs to make life impossible for those that don’t want to comply.

The right engine tuner writing the software can get the engine to pass sniff test with a full delete…..

I have a delete and tune on my tractor using a little MyGenius device I keep on the shelf. Before having the dealer work on the engine I can flash it back to the stock. However if the ECM is updated or replaced, I still have to do a download process from the engine, upload to the vendor who makes a new flash file, and then I can upload that. They charge a fee every time you do that, but it's reasonable. But it's not ideal.

Until I see it first hand it is nothing more than a rumour. All these manufacturers have spent 10’s of millions to try getting their engines to meet emissions and some computer guy can make it happen with a simple software upgrade? If this was possible, the engine manufacturers would be all over this, they would have 100% market share as anyone buying something new would never even consider buying something with emissions on it ever again. I think possibly they can make an engine pass a couple parts of the test, but absolutely not all of them. In no way am I in favour of the emission crap, that’s been the worst thing to happen to the internal combustion engine. |

Didn't Volkswagen get into trouble because their system would meet all the emission requirements when hooked up and being tested but once the test was done it would revert back to basically a pre emissions engine? Not related but our old 2004 mack burnt up the engine wiring harness and ecm. They were replaced a few years ago. Apparently moisture can make its way into the harness through the wire coating and short out the whole thing. Of course none available for 3 to 4 weeks.

They charge a fee every time you do that, but it's reasonable. But it's not ideal. The tractor I traded off had a delete and i clearly pointed out to the dealership it had an engine delete. Well they flashed the ecm and now the new owner is having all sorts of problems because the tractor wants to go into a regen. I feel bad for the farmer and he is pretty upset at me but, I did all all could to alert those involved. I gave the farmer the mechanic who did the delete as the dealership says they will not help the guy. My mechanic said this happens more than you think. What usually happens to the original delete software? can it be reflashed on this tractor or does the dealership software lock out any re tuning. What a mess. Feel bad but feel not responsible at this point. Reason they reflashed the ecm was for LOSS OF POWER. It turned out to be a dirty air filter. This time I wish they left the computer behind and went old school. Torriem could you give more detail of the equipment you need for a tuner. Most farmers dont do this on their own at least the guys I know. |

Would just need it reflashed with the delete tune in it. John Deere is the worst for this. If there is an engine problem first thing they do is re flash the computer. And kind of problem on the tractor must be the tune. If your tractor has been running for hours without trouble it is not the tune. They don’t just wear out and go bad. A bad tune will show up as soon as it is started.
As to loss of power from dirty air filter the computer would have shown that if they looked at boost and air filter restriction.

Torriem could you give more detail of the equipment you need for a tuner. Most farmers dont do this on their own at least the guys I know. When I bought the tune from Ekotuning there wasn't a dealer close by so the dealer I was working with sent me a MyGenius DimSport handheld programmer. This is used for all kinds of engine programming all over the world. I believe he hard-coded the DimSport to work only with John Deere engines and once it had read some parameters off the engine it was locked to that engine semi-permanently. Once the tunes were coded up and sent to me I put them on the DimSport with a laptop and then used it to program the engine. Since my delete is software only (absolutely no engine mods), I can use the DimSport to put the engine back to stock anytime I want, and before the dealer does anything to it. If the ECU gets reflashed, Ekotuning charges a fee to regenerate the tune for the new ECU parameters which I can read with the DimSport. PM me if you want a phone number of an Ekotuning dealer to talk to about this. I did have a case where the dealer reflashed the ECU and I hadn't had a chance to flash it back to stock first. Ekotuning was able to get me a new flash but I had to wipe the DimSport and get it to re-learn the engine. Was more expensive than if I had flashed it to stock before the dealer worked on it. But it wasn't that difficult to get it tuned again. |

There is no need for the Deere dealer to ever reflash the engine software. Tag the plug in that it is deleted and also write in there to not flash without permission.
