EBay Bans Sale of Aftermarket Emissions Defeat Components

ebay bans sale of aftermarket emissions defeat components

The tuning world has always had to adapt to changing laws and regulations, but the industry is grappling with tightening emissions regulations that have changed almost everything about how they can do business. Iconic Miata tuner Flyin’ Miata announced it would no longer sell completely converted cars or conversion kits because of the changes, and now eBay has banned the sale of emissions defeat devices.

Road and Track became aware of the changes at eBay through a private automotive Facebook Group, where a user detailed their experience selling a tuning device for Hondas. The sale ran afoul of eBay’s Emissions control defeat devices policy, which states that users cannot list “products that bypass, defeat or render inoperative emission-control systems.”

eBay’s ban covers hardware and software and includes language that bans components like modified ECUs, off-road exhausts, and more. The company’s information page says that it has the policy because it “helps our buyers and sellers follow government regulations,” but in reality, eBay could face thousands in fines for every sale it allows. 

The EPA notes that its initiative focuses on “those who manufacture, sell, or install aftermarket parts known as defeat devices.” Though it will fine entities it finds in violation of its policies, the EPA may allow a rollback of fines for companies that take voluntary action to remove products from their business.

    Most newer vehicles the emissions are controlled by microprocessors so tampering with emissions can effect the overall performance of a vehicle. Best to leave the catalytic converter in place unless you have the misfortune of having it stolen and then when you replace it you can have a steel plate welded below it to prevent future thefts. Eventually pollution devices will not be necessary if all vehicles are EVs. Don't really have an desire or need to make my vehicles run any faster they do just what I need them to do and they have enough power to meet my needs.

      The anti-theft plates are typically riveted in place or held in place with security bolts. Welding makes it impossible to repair certain things like replacing a cat that's gone bad or replace a transmission rear seal (RWD vehicles) without resorting to a torch, which you don't want to do on frame rails, especially on BOF vehicles.

    What about tuning devices which can improve performance while still meeting emissions standards? I'm guessing they've banned those too.

  • VoGhost Five years ago, Tesla was ten years ahead of the competition. I haven't seen anything to suggest that's changed.
  • Varezhka They cheapened out on the hardware side too, so we'll see how much they can improve with the software updates. I know they're using faster processors with some of their newer vehicles, but not sure how much faster.
  • Varezhka I mentioned yesterday that I wasn't a fan of Mazda Connect v1.0 in MX-5. Now I count Mazda Connect v2.0 in Mazda3 as among my favorites. Clean, fast, and intuitive without being a distraction to driving.I also don't mind the v7 BMW i-Drive, though BMW also seem to go back and forth between quite good and quite messy between updates. I also liked the screen position better before they incorporated touch.
  • EBFlex When you support socialism I guess it makes sense to support countries that are socialist.This is absolutely ridiculous though. The dementia-riddled, installed president won't allow drilling here and as recently as early November said "NO MORE DRILLING" ( https://www.forbes.com/sites/davidblackmon/2022/11/07/biden-promises-no-more-drilling-just-days-after-demanding-more-drilling/?sh=eeef4a578e7a )Why help people here and give them work when you can ship it off to Venezuela? Next, he will be advocating for giving jobs to China who are continuing to commit crimes against humanity (something the elf Fauci wishes he could do).This is insanity. We have tons of oil here. We should be drilling for it and aggressively building refining capacity to turn it into lovely, lovely gasoline and diesel.
