California Smog checks will now check for "illegal" software modifications
California Smog checks will now check for "illegal" software modifications
Looks like the crackdown will start sometime this month:
Hopefully tuners will go through the CARB certification steps to save us some hassle?

i doubt that violators will have much to worry about. i took my cayman to a smog check the other day and the guy said he couldn't do it because the engine isn't in the front, or it's in the middle, or that he couldn't see the engine or something. don't really remember what his excuse was... anyway, it's the same guy that's been doing my 2001 dodge ram 1500 and my vantage for years.

This is not that big a deal. At the most, Smog checks are done once a year. As part of the process for your yearly inspection, revert to the original ECU flash AFAIK is fairly straightforward. After inspection Reinstall the ECU flash and drive safe.
I was thinking about the flash to stock then flash back, I guess that it would have to be done right before the smog check if the tune was done for 200 cell cats, right? How long until the ECU detects any discrepancy between upstream and downstream O2 sensors and throws a CEL? For CA residents, there are other ways to do it so as not to have to smog every two years. I have done it for my 76 2002 that has a M42 swap for the past 9 years and just did it for my V8V.
