Alex’s Stage 1 tune will pass CA smog. That’s one of the first questions I asked Alex before I bought his Stage 1 tune. All monitors should set to “Ready” once the drive cycle has been completed. CA allows one “not ready” but it can’t be the O2 monitor. I currently have a “not ready” on the O2 monitor. All others are ‘Ready”. I need to drive the car more to clear O2 to ready. I use a cheapy Innova scanner that can check for Monitor Readiness.

Longboarder, which monitor or monitors are “not ready”?

Alex has consistently posted to return to the stock tune before emissions testing.

hmmm, that may be but I understood all Monitors can go to "Ready" with Stage 1 tune.
