Since plastic is banned in those states, how will they make the blades and components for the wind mills to generate electricity? Or is that plastic good for us.

any flashed tune, flash back to factory tune will pass with no issues once the monitors are set. |

can anyone confirm BM3 flash back to stock will return the original checksum and pass the latest smog verifications?
some people sam the BM3 flash changes the DME permanently that it's impossible to flash back to stock? |

There are companies staring up right now to recycle them.

Has anyone actually failed smog yet for a flash tune? Until I get some real world experience from folks, I'm planning to go in with my flash tune and see what happens (in 1 year).

Any reduction in pollution is good…it's a journey, as they say. Given we are several months into this regulation there doesn't seem to be much of an issue. |

For what it's worth, I know of an NM tuned N18 MINI engine that passed a star station inspection under the new rules. NM verbally claimed the checksums would match--different engine, different tune, but same manufacturer so I thought it worth mentioning...

That NM tune or whatever looks like a piggyback, which if it is then that doesn't affect the CVN/checksum as it is still using the OEM tune, just fudging the input/output numbers or however they do it. Flash tunes are where you have to worry about the CVN/check sums

I mean, I understand that in theory, this is true. What I'm asking about is real world experience - for example, visual inspection - some places spend 10 minutes and get under your car, others spend 10 seconds and don't. I am betting this isn't up to the discretion of the tech, since it's data, which they have to send in, but figured I'd ask if anyone gave it a shot anyway.

I feel like we have too much short term solution and not enough long term consideration. We are essentially creating band aid fixes to please the masses and their "I want it now" mentality. Take electric cars for example, yeah, EV are a great to cut fossil fuels and emissions, but what a lot of people don't realize is at our current rate of demand and what the world gov'ts are pushing to achieve for EV sales in the near future, we will deplete the Earths lithium reserves in under 30 years. I went down a rabbit hole not long ago, I don't remember the details exactly but I read that it was being pushed to have something like 80% of new vehicle sales worldwide be EV by 2035, something like that, so I sat down and figured out the math and it's actually under 15 years before we deplete lithium reserves if we do actually meet those demands, but I think 30 years is more realistic as engineering and manufacturing will advance and require less lithium per vehicle over time. Regardless, we don't have an endless supply of lithium, and with more and more devices becoming wireless and requiring battery power, we use more and more lithium every year. We more than doubled our lithium demand between 2016 and 2020, and thats without a massive increase in EV production like we will potentially see over the next 5-10 years. Hell, 2021 already saw an 80% increase in EV sales globally. Additionally, we don't have the means to recycle batteries in a clean, cost effective and efficient way that doesn't require massive amounts of heat and power, so what are we going to do once we have millions of vehicle batteries needing replacing every year? It's a great "right now" fix, but what about long term? And yes I know, this is coming from someone who drives a smelly, dirty, evil diesel, but I'm not against EV. I've been watching and waiting, and I'll get one once they can meet my demands of a vehicle, they just aren't quite there yet.
