CA Smog monitor readiness emissions California

IllSic_Design · 12-06-2017, 06:52 PM

Sorry if this has already been asked, I searched pretty well but I'm sure I didn't search the right terms. Just wanted to make sure that all my monitors are set and the ones that are not available are not applicable to our car. I have to get my car smogged, put on OE dp's and stage 0 MHD, here is what I got. Also, I have no check engine light but do have a 2AAF fuel pump plausibility code, can they reject me for that? Thanks for the help.

I think if you have no check engine light, and all monitors are ready, you are fine. Can anyone else confirm?

I also have a related question -- Do I need to go to MHD stage 0 for smog check? If I have an MHD stage 1+ tune flashed and all my monitors are ready, am I good to go get a smog check? I think I should be fine since they are just checking monitor readiness, and no check engine light, right?

I got it tested this morning, all was good and no problems passing. Now I just need to buy some engine mounts and then I'll throw the dp's back in when I swap those.

Skyotee why not just flash to stage 0? It takes 2 minutes to do and then you don't need to worry about it and can switch back in another 2 minutes.

Because if I flash back to stage 0, it clears readiness. Then I have to complete a drive cycle to reset readiness.

Unless I am mistaken? A stage 0 reflash clears codes & readiness, right?

I just drove my normal commute to work(which is 70-80mph freeway) and all monitors were ready. I did do the 2 min cold start warm-up and 3min at 20-30mph out of the drive cycle procedure though just to be sure they would all be set.

Thanks for the info IllSic_Design! Good to know you passed, and I might try a re-flash to stage 0, since it seems like you got readiness to set pretty easily. Trying to get my smog this weekend, so I would need to get to readiness pretty quickly.

Unless someone can confirm that an MHD tune will pass, regardless of stage, if ll monitors are set to ready?

Also, does anyone have the exact drive cycle details for an E9X bimmer? My XTERRA had the complete drive cycle in the owner's manual, but I have not seen that detailed out for my bimmer...

This is what I referenced. Came from another thread on here about smog checks and monitor readiness.

An update, got my car smogged again this year after flashing back to stock(and putting stock DP's back on)

A good thing I didn't know, CA let's you pass with the EVAP readiness not set, which was great for me as I was having trouble getting that one to set. CA only lets you pass SMOG with that one readiness open, no others.
