A gray area on smog
Talked to a few tuners in the Bay Area where I live about the ca smog laws. Does anyone know that if you do a tune will the car pass smog?
I'm hesitant on doing a mid level tune with 2maps
Thanks

You can do a tune and also do the force obd patch on this forum and it will pass. The tune isnt the problem its the visual that can fail you. I did mine for 2015 and it passed the obd test thanks to the force patch and they no longer do the sniffer test. When Ive gone to do the tests they guys doing the smog were pretty laid back and didnt care much for the mods.

I can confirm that the force OBD patch works perfectly. Just make sure you don't enable any monitors that don't exist otherwise they'll flag your car. Just passed smog with rear 02 disabled, full tune, and all I had to do was unplug my wideband gauge.

The forced pass rom patches are to disable smog dtc. If you have the patch doesnt mean youll pass smog.
Especially a car on 91 w/out a catalytic converter.
The e85 cars passed cause they run 14.7 on the meter since the different afrs it runs clean at.
I know the smog is changing to just readiness monitors but the visual is still there.

Not sure about CA but in IL we can pass with a lot of stuff if you read some good threads on this site. Our testing isn't by tailpipe, they just use an obd2 scanner to see if you have any codes.
PS and they check readiness of all the systems, only 1 can NOT be ready to pass.

I would think if they test whats actually coming out of your tailpipe you would not pass, but I'm sure someone here knows more. But if its just a OBD2 readiness test then read up on how to pass emissions on evos. You can make your ecu tell their computer that everything is ready and working well even though it may not be ;-)
