The CARB standards have been critical for smog reduction in California, which was important both environmentalls and in terms of public health. Wanting revisions to the standards, or criticizing enforcement seems like a good debate. But hating the standards just because is a little like hating science or public health.
I am curious about what VW actually did with the electronics. Full throttle enrichment maybe, as p-hack says. K like that idea, because it might explain the report's mention that the illegal changes increase NOx dramatically.
[EDIT: deleted graph of stoich for a gas engine]
What else could they be doing?
Maybe at speed for a sustained period of time, the ECU chages parameter too, perhaps the a super-lean mix?
