Passing Smog in SoCal with mods

FL 4Motion

Interesting, I could have sworn when I perused the most recent EPA regs that there is still a carve out for converting street cars into non street legal race cars exclusively for the track. SEMA brought a lawsuit a few years ago to get this carve out bc otherwise ALL aftermarket car parts would have become illegal overnight.

Regardless, if EPA or CARB actually was only motivated by wanting cleaner air (which btw I’m all for personally), and not some socialist political agenda to push us away from POVs, then the ONLY thing that matters would be a sniffer test. After all, the only thing that hurts the environment is the tailpipe emissions, not the computer programming in your ecu. That would be a common sense practical application of clean air laws.

I agree with you about emissions. What they should do which makes too much sense that they won't do it is if you modify your car, it should have to pass a sniffer test instead of the obd test. And even if there were some kind of surcharge, that would be fine too. My car still has cats and I run e85. Probably runs cleaner than a stock z.

Yup, most good tunes that still maintain the cats actually run as clean or cleaner than stock but I suppose it’s not politically correct to “encourage” souping up cars anymore

Flashing back to stock with uprev would apparently delete the tune forever/require full retuning due to uprev software changes over the years, so the solution is a secondary ECU from eBay with stock tune and one of the fobs reprogrammed to match it. Back to the tuned ECU for track days.
