What law? I'm in California are you referring to?
California now enforces a law they actually made back in 2013. The change to enforcing it was done middle of last year. The Volkswagon diesel debacle finally made them implement it all. Basically, CA decided it cannot trust any vehicle manufacturers or drivers on the road with regard to their emissions. So what they now require is all ECU programs to be registered with the state and they go through this whole testing procedure to know that the specific ECU code is emission compliant. If you have a tuned car, you WILL fail smog check now. A smog check does do an actual emission check of the specific vehicle sensor data, but they also now look at ECU checksums to detect a non-compliant tune. This means that if your car is tuned at all, you fail smog and cannot get registration tags. They do allow
OEMs to register "performance tune products" that modify car performance as long as they are staying within emission specs, but you as an individual cannot go through this tune registration process without spending many thousands of dollars and time to get your ECU tune registered and tested with the state. Thankfully, Up-rev has a CA compliant registered tune you can put in your car to get a bit better performance than stock. So if you currently have an Up-Rev tuned car, you have two options before your next smog check: put the stock tune back in AND remove your Up-Rev license as that will cause a fail, or buy a generic CA compliant Up-Rev tune and have that installed on your car.
My problem is that my engine has JWT camshafts, larger injectors, and runs E85. I cant run a generic tune that is registered with the state. I could go back to stock injectors and regular (expensive!) gas
(E85 is normally $2.49/gal at the pump), but I really don't think a generic Up-Rev tune for CA compliance will work with larger degree and lift camshafts. Id have to take the engine apart and put the whole thing back to stock, which would be a lot of money and time. I could do it of course, but at this point I also dont even want to go back to a stock M35. So I am left in the position that I cannot register the car, even though the car was registered before this change to the law and meets all CARB smog emissions tests for being within regulations. Plus, I already bought a 4L crankshaft from a VQ40DE I was really looking forward to trying to fit into my engine as a next project hopefully this summer.
