According to records filed in the case, Achtemeier conspired with mechanics in garages and operators of truck fleets to disable the anti-pollution software installed on diesel trucks.

Coconspirators who wanted to disable their trucks’ pollution control hardware system—a process commonly known as “deleting”—sought Achtemeier’s help to trick the truck’s software into believing the emissions control systems were still functional, a process known as “tuning.”

Monitoring software on a deleted truck will detect that the pollution control hardware is not functioning and will prevent the truck from running. Achtemeier disabled the monitoring software on his client’s trucks by connecting to laptops he had provided to various coconspirators. Some of the coconspirators would pass the laptop on to others seeking to have the anti-pollution software disabled on their trucks. Once the laptop was hooked up to the truck’s onboard computer, Achtemeier could access it from his computer and tune the software designed to slow the truck if the pollution control device was missing or malfunctioning. Achtemeier could “tune” trucks remotely, which enabled him to maximize his environmental impact and personal profit.

            The EGR and DPF systems used in diesel trucks cause (or caused, it’s been a while since I last looked it up) a big reduction in fuel mileage. I think it was a 2 or 3 MPG reduction.Doesn’t sound like much, but it adds up when you are running 200,000+ miles a year per truck. With the system running I believe the average fuel mileage for the trucks in our company is around 6 to 8 MPG depending on the route.

            Additionally the systems are expensive as all get out to repair and maintain. When the DPF and DEF systems on my truck went out, the truck was down for 3 months waiting on parts, and from what I heard from our mechanic, the final repair bill was around $15,000USD.

            That said, the fines for bypassing the emission systems are big enough that it’s really not worth it, but some owner operators don’t realize it as many don’t run their trucks like the businesses they are. They just know this is expensive as hell and they can reduce the cost by bypassing them.

              I think it’s worth noting that this is an environmental benefit, not only an economic one. In other words, it’s not that people defeating the emissions control devices are making their trucks purely worse for the environment for their own selfish benefit; it’s that they’re making a trade off between increased ‘regular’ (for lack of a better term) pollutant emissions like NOx/SOx/particulates, and decreased greenhouse gas emissions (CO2).

              I’m not saying they’re altruistic – obviously they do it to save money (at least until they get caught and fined) – but I am saying that we can’t just assume it’s bad without first doing the math and making a value judgement about what sorts of emissions we care about.

              Geeking out about an edge case where not having the fancy emissions controls is better: using biodiesel

              There are also more complicated considerations, such as how getting rid of these emissions controls and retuning the engine may also allow it to run on higher percentages of biodiesel. The trade-offs associated with that are not only the fact that the fuel becomes carbon-neutral (net CO2 emissions go to zero, at least for the percentage of the fuel that is bio- instead of dino-), but also that biodiesel naturally has zero sulfur in it (which means zero SOx) and burns cleaner (fewer particulates) and hotter (more NOx) than dino-diesel. On top of that, more NOx could be a bad thing or a good thing, depending on whether you’re driving in a NOx-limited or VOC-limited regime.

              In other words, using 100% biodiesel in an urban environment (VOC-limited) is IMO enough to actually justify preferring not to have the fancy emissions controls for legit environmentalist reasons: the better efficiency in general (as the parent comment mentioned), zero net greenhouse gas emissions, zero SOx, irrelevant NOx, and all at the cost of only moderate particulates (more than would be emitted from a vehicle with a DPF, but less than would be emitted if the same car were burning dino-diesel).

              Of course, none of those benefits occur unless you actually seek out B100 (or at least, significantly higher percentages than the B5 that normal diesel can be blended up to), and that’s a motivation much more associated with the hippie types that drive VW TDIs and old Mercs, not truckers.

The fact that people don’t understand it or appreciate how significant it is doesn’t mean it’s not a “now” problem, it just means it’s not a problem that’s ever going to get fixed because people like you don’t and won’t ever consider it a “now” problem. Enjoy the challenge of struggling your way through the increasingly impossible economy, it’s not going to get better.

                Don’t quote me on it, but I believe that the emissions tech is efficient enough that even with the increased fuel consumption there is an overall reduction in emissions across the board. That was my understanding when the tech was first being fazed in back in the mid to late ‘00’s. Whether that was true or just propaganda, don’t know. I just knew that full compliance was required to run in California and a few other states.

                  If it lowers MPG, it increases CO2 per work done. There’s no getting around that.

                  I always thought that the way auto manufactures went about meeting emissions by adding more parts(that will break and need replacing, $$$) and lowering fuel economy(I wonder who benefits from that?) to be at best, lazy and at worse, suspicious. I recently learned about a Swedish engine manufacture called Scania that’s managed to meet emissions without DEF. I’m definitely gonna keep an eye on that company.

                  For now, I’m just gonna keep making biodiesel for my farm and burning scrap wood for heat. The emissions tech they’re piling on to diesels actually precludes running biodiesel in them, so it’s not exactly like I’d ever be getting any new. Not like I’d want to buy a one ton piece of spyware anyway.

            My understanding from past reading is that there’s a history of diesel trucks pulling off emissions control hardware to increase their MPG somewhat, so they save money on fuel. First ran into it when reading about the practice in Europe, but also happens here in North America.

            I don’t know whether it’s possible to tweak the computer-controlled system to achieve a similar effect, but it’d make sense.

        For semi-trucks at least, my cousin (who drives a truck) told me it costs him a lot of money to have the DEF systems on his truck and operate them, and it costs him money he would otherwise be making on his deliveries.

        It refunds itself the second you have to replace any of the emission components and if done early you refund it by getting better MPG and not having to spend money on diesel exhaust fluid.

        Easily. Read my other comment, but this would pay for itself in a single afternoon if you didn’t maintain your vehicle and would otherwise get shutdown due to an exhaust failure.

        Or if you drive a truck in stop and go traffic, and the filters clogged up early, causing you to delay and let the exhaist system do a cleaning cycle (take 1hr, requires engine running and high throttle.) Etc etc.

      From the article:

      Achtemeier charged as much at $4,500 per truck for work that often took him two hours or less. Achtemeier advertised his services on social media nationwide, doing business as Voided Warranty Tuning (VWT) or Optimized Ag.

      When you run out of DEF or the DPF is clogged, you can’t run your truck for more than a brief while. You get half output in a limp-mode to go refill your DEF or have the DPF serviced. DEF is the reactant for the exhaust that makes diesel burn cleaner, but means modern trucks have 2 tanks now. Users hate it, but it cuts emissions massively. Also adds a few grand to the vehicle exhaust system in hardware and sensors and control units. Anyways:

      Time = money.

      For a commercial or even semi private vehicle if you bypass even one indicent of downtime by doing this is paid for itself.

      That said, the DPF is a filter, and can physically clog and cause an exhaust fire if there is no monitoring software. I hope at least this guy had it wait till it was almost critical and then stop, not entirely disable the stop signal. Otherwise there is a serious risk to the vehicle and passengers.

        It’s not an anti environment thing, it’s a money saving thing (as in, they don’t do it to intentionally harm the environment, it’s collateral damage). You spend 4.5k to make your engine reliable for hundreds of thousands of miles instead of having to spend 10k (if you’re lucky) every 100k miles to keep it running.

    The antipollution on a diesel engine (at least a big one) essentially reroutes the exhaust back through the engine and reburns it again. Before the antipollution devices were in place it wasn’t uncommon for big diesels to get 500,000 miles before they needed to be replaced. Now with the antipollution devices they’re getting somewhere in the neighborhood of 100k before they start having problems of significance.

    Those engines and their maintenance are expensive as hell. It saves a whole lot more than the $4,500 having that done. It saves them hundreds of thousands of dollars over the long haul.

        I’m assuming the engine would need some modification to run propane? If not to the cylinders themselves, to the fuel supply? I assume propane would be largely similar to LNG vehicles? I really only see that on city buses and assumed there was a range reason for that.

          Propane is way less energy dense per volume than diesel, so it isn’t feasible for long-haul trucking. CNG/LNG is more energy dense than propane, but still nowhere near that of diesel fuel, which is why you see it in busses and garbage trucks. I know a few massive fleets (UPS comes to mind) that use CNG for some of their local routes, but that is probably more for the “green” optics than anything else.

            propane is like 3/4 density of petrol and gram per gram carries more energy (propane 0.58g/ml, petrol 0.7ish g/ml) it’s slightly greener because it contains more hydrogen so more energy per carbon emissions

            LNG is cryogenic, has even lower density (0.41 to 0.5 g/ml depending on temperature) and CNG is less dense still depending on pressure

          petrol engines need little modification, what is def necessary is another tank for LPG. different fuel supply system is required, but if original is kept in place either petrol or LPG can be used as needed. propane is a liquid under pressure and much denser than gaseous compressed methane, and not cryogenic like LNG. diesel engines can also be converted, but it gets harder and requires either small amount of normal diesel used or installation of spark plugs (it’s still diesel cycle)

        God I hate comments like this, that are so un charitable. He’s giving us more information and context which is important and adds to discussion and here you are trying to start shit.

        This happens way too often on here, people providing nuance or a different perspective and some douche sliding in “so you think everyone should DIE!!!” putting words into OP’s mouth and attributing malice…

          A point was trying to be made. One - the information provided is absolutely biased and possibly untrue. Performing maintenance on your vehicle is a fact of life. Using emissions as a scapegoat and justification to pollute bothers me more than my comment bothers you.

          Fuck polluters and fuck their apologists.

            Everything is on a scale. The pollution control equipment only trades air pollution for increased throughout in landfills, increased industrial emissions to the air, water, and land by necessitating more frequent replacements, as well as more funds in the pockets of capitalists. Pick your poison because you’re never going to come away squeaky clean.

      I actually decided to search this because I thought the whole point of DEF was so trucks wouldn’t need to use an EGR like every car does.

      Apparently emissions is complicated and expensive lol, so lots of trucks have both.

      Newer models however have started creating systems that remove the EGR and instead rely solely on the SCR with a bigger DEF tank and a cleanup catalyst.

      I think DEF is still the right direction. Exhaust recycling has a ton of downsides that took car OEMs a while to hack their way around (or give up and plan for 150k mile expectancy).

      4,500 for a mod though is still pretty expensive for something you can do yourself. Most of that cost was probably due to it being illegal, not because it’s hard to accomplish.

    It’s okay to keep the hyphen in there. It’s more readable, and also it’s once again a word.

      The summary says he was having accomplices connect a laptop to the vehicle and then remotely accessing that laptop. Sounds like regular old ssh or rdp.

      Most cars come equipped with a sim card these days and there’s lots of news about how car companies are sending data about your driving habits to insurance providers. So um… Yeah.

      Manufacturers try really hard to stop their proprietary software from getting out into the world, because when it does this is exactly what happens.

      Case in point: I have a $35 phone app that lets me change software configurations on my BMW, and it is great. Can’t change anything related to engine, aftertreatment, or safety though…which is a good thing.

        Flipside of this coin: this results in repair monopolies because users cannot repair their own vehicles and equipment and manufactures use this exact excuse to claim they HAVE to run a monopoly cause the EPA. Literally John Deere has said this.

        In truth, illegal vehicle mods have been and will always be a thing. Manufacturers should still provide all the tools to users to repair, and emissions checks on trucks will have to be smarter to catch cheaters. Make the penalty for a deliberate violation (willful not accidental) so egregious that no one would consider it, even if it saved 50k+ per truck.

    Why? Just Why?

    I mean sure, there is some money aspect to it, fine.

    But why spend all that time and energy just to be able to pollute more. I mean, that is the benefit of more pollution? Even if you don’t believe climate change, polluii less shouldn’t be that hard to understand as something positive?

    I’m just… Not getting this. I’m assuming the guy has a mental illness that would explain this, maybe?

      If the “delete” was removing their catalytic convertor and not just reprogramming the ECU then there is a mild to moderate performance increase caused by reducing exhaust pressure. If it’s easier to push the exhaust out then there’s more power going to the wheels.

      If it’s just ECU changes it’s probably related to the air/fuel mixture it’s using. Often douchebags will hack this to “roll coal” but changing this can give you increased horsepower at the expense of emissions.

      As someone whose car has a tune but still passes emissions inspections, this guy is both bad at tuning cars and also an asshole.

      Believe it or not there is a subset of the far right who vehemently believe we are ruining the atmosphere but not pumping ENOUGH carbon into it.

      It’s a weird reverso climate change belief. These people blame all the historic hurricanes, wildfires and changing temperature on the completely unfounded idea that humans are limiting their CO2 output.

          During the July 20 edition of Your World with Neil Cavuto, Fox contributor Brian Brenberg called for more coal plants as a solution to extreme heat, claiming, “I think most of America wishes the coal plant was still there because… more people could be in a cool environment and be safer.” [Fox News, Your World with Neil Cavuto, 7/20/22]

          Climate denier Patrick Moore, a right-wing media darling who works as a nuclear energy consultant, has refuted the idea that carbon dioxide levels are “getting too high” due to human activity. In 2022, Moore wrote on X, “It has been known since at least 1920 that adding CO2 to greenhouses and even to open air causes a huge increase in plant growth, with no harm caused to plants or animals.

            We need to put laws in place to limit free speech for either companies or people with large followings. If you have a large following you should not be allowed to say what you want because it ALWAYS ends bad.

            You can say what science knows to be true and if you make bullshit claims that can be disproven you van either admit that you don’t know what you’re talking about and people stlhould stop listening to you, or you go to jail
