I can tell you from experience they are not checking for deleted codes. Active codes, yes, of course. The big thing for me was monitors. There are a group of 10-12 they check for. They will fail you if a monitor such as the evap monitor is not enabled. Simply unmarrying an AP is not enough to get the monitors turned back on. It took quite a few cold starts to get mine enabled. Give yourself enough time between the time you unmarry your AP to the time of your smog check for enough cold starts. I can't tell you how many it takes as every car/ECU is different.

Update: I was able to obtain a Stock ROM from my tuner. He sent me the rom, and I had a buddie who had the EcuTek software on his laptop, reflash my ECU back to the stock ROM. I drove approximately 80miles, cold started maybe 6 times. I went back and got re-smogged and passed! )

I passed SMOG in January with my swap with BAR certification plus a COBB AOS and COBB Ecu tune with CARB stickers in the engine bay... They just looked at the stickers and didn't check the actual ECU tune at the SMOG shop.

The 91 ACRN map included with the Accessport. They have all the CARB documents on the COBB website.

This was not a STAR smog station? I thought they were suppose to check even the CARB approved maps.

It was a STAR station. I thought they would check the maps too, but I think the sticker allows that to be bypassed.

I wonder if they're still updating the process or if that is going to be how it works.

I have a 2000 RS with a 99 EJ207 BAR'd as a 2004 EJ205. In years past, 04 WRX MT ECU was good enough to pass since the car had all its monitors pass and no CELs.

Wish me luck, I'm going to try to pass with a Cobb APv3 OTS ACN91 Stage1 tune. I swapped out my 816cc injectors for stock 440s, Perrin EL header for stock manifold, k&n typhoon for stock box, and MRT DP for stock DP. Non-stock items currently on the car are only the Grimmspeed Up-pipe and Prodrive axle back.

My smog guy is strict, but he doesnt care about up-pipes and axle backs.

Not much info out there regarding the CVN and running the Stage1 map and smogging though.

Update on this...

Just passed SMOG for the second time with the swap. This time I was running:

-VF48
-STI Uncatted uppipe
-Resistor mod
-COBB 3-port EBCS (VERY well hidden for visual)
-STI Injectors
-AEM 320 Fuel Pump
-Pro Tune
-COBB AOS with CARB sticker

Passed with zero issues! Very clean on the charts/stats actually, not like I would fail the sniffer just the visual would be the issue.

Rumor has it anything 2005 or older isn't in the ECU database for CARB, plus my CARB sticker for the COBB tune is still on the car along with the BAR swap sticker of course. The SMOG guys see those and basically give you a pass for a lot, and they DID NOT scan the ECU for the map just the readiness monitors and for CELs.

Theoretically this means quite a few other mods are quite possible, along with changes with engine internals since the ECU tune is open to pro tunes. Turbos are pretty much free game too, as are injectors that look OEM (IDs would probably fail visual). Wondering if I could even get an OEM twinscroll downpipe to pass since they didn't go under the car

Newer cars like the BRZ and VA WRX/STIs are getting their ECUs scanned now though, wouldn't try to do too much with those. But an 04/05 STI should have lots of possibilities.

Dumb question, how do you know they didn't scan the ECU map?

It actually takes a considerable amount of time to do. I watched the BAR ref scan it during certification, and sat and watched what the smog station did and asked too since the guy who checked me in also had a swapped Subaru.

If they scanned it they would have found it didn't match the COBB CARB tune I have the sticker for, which is what the BAR guy did. Other newer CANbus cars are getting scanned and failed (BRZs for example), I've seen a couple posts on other forums about it and mention of it on social media.

Got it, thanks!

I guess most smog guy probably won't bother scanning low-risk cars...or do you think perhaps the scans are initiated from the state?

I just swapped to a stock ECU on my 2002 WRX to prepare for next year's smog (takes awhile for all the monitors to be ready with my driving habits). Maybe that's something I don't need to do?

The state supplies the reference for the maps. I'm starting to suspect its only CANbus cars in the system but can't confirm it.

Probably unnecessary.

Hide a camera in the next car that gets smogged to see if they scan it

Is it going to look different from what they usually do hooking up to the OBD2?

Of course. Checking readiness monitors takes seconds like with any OBD scanner. Checking a map takes awhile.
