Tune in CA, will it pass smog?

[Berns]

I wanted to know if there any members on here from Cali that have a tune and did you have trouble passing smog?

I don't think you'll have to worry. The changes a tune makes aren't enough to really set off anything. As long as the emissions systems are 100 percent they should keep up.

Thanks. My concern is that I keep reading about techs being able to plug into the obdII and then see that that PCM is tuned and then fail me.
Something about the machines being able to read and compare stock calibrations.

They plug in but cannot see the tune, all they can see if there is a pending MIL, a MIL that has not fully reset and one that is active.

We have plenty of CA members with tunes.

Thanks.
I took the plunge and contacted PCM of NC to tune my ECU and would hate to have it refreshed to get it to pass smog.

Got truck tuned this weekend and it passed with flying colors.
Tune not detected.
