so you have zero clients with current registration on a vehicle from 1976 or newer from California? yikes.
I cannot be responsible for every customer's whereabouts, or where they register their vehicle. Or how they go about passing smog.
I believe in this crazy concept called "personal accountability" .
California has become such a professional hazard due to their respective political climate and ever tightening emissions laws, it is hard to navigate through what is legal, and what isn't.
My tunes are not CARB EO'd, so if we are using that as a litmus test for acceptable versus not, then that should answer your question.
That said, I do not defeat emissions devices (o2s get left on, evap remains intact, etc) in my tunes.
Some things , mentioned by others in their own posts, do end up passing due to grey areas and "ref's discretion" even though they are technically not legal.
I have had customers that reside in Cali that have previously passed smog and did their due diligence to keep their setups smog legal, that now cannot due to having a non-OEM calibration detected. Certain localities within California are looking for non-OEM calibrations and have the means to do so!
Again, alot of this is very grey and subject to what side of the bed the smog ref woke up on that morning.
Officially , I would tell you to follow your local guidance on engine modifications. They will be the best and most up-to-date authority to speak on the subject.
Speaking only on the subject of emissions output and fuel consumption- my tunes in most cases, if anything, burn cleaner than the factory calibration due to extra timing producing a cleaner burn.
I have passed EURO IV emissions compliance on other older platforms that use the JTEC controller, and see similar stringent emissions standards.
I care about the environment and put my best foot forward towards calibrating with a socially conscious approach.
