There trying to cut costs from smog shops extra paperwork etc. You will still be required to smog your car but it will be a readiness test, just to make sure all systems are performing as they should. There won't be a sniffer for 2000+.

If they are interested in reducing pollution, then they should eliminate the visual and functional and keep the sniffer. Smog testing is done to mitigate pollution. Who cares if the car is modified as long as it's not grossly polluting. That law is absolutely retarded.

No one seems to know for sure yet. Not a lot published about that yet that I have seen. Tons of speculation, so take that for what its worth since it is the internet.
An interesting thing I came across not too long ago was that the FAST LSx intake is now CARB approved. However, the wording in the EO states "This Executive Order is valid provided that the installation instructions for the LSXR Intake Manifold will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer."
Thread about the EO here:

Here is a link to the EO:

How will they know? Not entirely sure but some of the leading speculation with the OBDII scan is a checksum comparison...or something like that. Not really too sure about that so take it for what its worth - internet speak.
I know the eForce Supercharger has something similar in that it is only legal if you use the tune provided. Again, not sure how they would be able to check. I'm would imagine they would have some plan in place.
I think the biggest thing that jumped out at me from AB 2289 is this:
'B. Vehicles known to release large amounts of pollution must test at stations with the highest performance ratings."
Not sure how they are going to determine how a car does or doesn't fall in this category.

At the smog test, they connect to your PCM via the OBD2 port and read these things (using Mode $09):
- CAL ID for each segment,
- CVN for each segment,
- VIN of your vehicle,
they then use the VIN to look up a database containing valid CAL ID and CVN values for your VIN (this is already in place for 2005+ cars);
the CVN's are like checksums; when tuning software writes to the PCM, the tuning software calculates what the CVN should be for each segment and writes it to the PCM; when you turn on the key, the PCM performs the same CVN calculation and expects to arrive at the same values;
if you have significant engine mods, you would have had your PCM tuned, which means the CVN for the engine segment now differs from original...
if you deleted codes, then the engine diagnostic segment CVN differs...
if you had your auto trans tuned, then the trans segment CVN differs...
if you changed your ring/pinion ratio, then your speedo segment CVN differs...
if you changed your fan on/off temperatures, then your system segment CVN differs...
[ if GM reflashed your PCM for some reason or other, CARB will know about it (since the PCM is an emissions device), and the new CAL ID and CVN will end up in the database ]
if your car is a 2005+ they will definitely see the differences in CVN values, and they will fail you;
if your car is 2000-2005 they may still be able to pick up on these differences, even tho they didn't legislate for a database for cars prior to 2005; that doesn't mean they don't have a means of looking up and checking (they have had the ability to store the CAL ID and CVN values from all your previous smog tests, and they have the computing ability to detect differences, they just can't necessarily compare them to the OEM values);
in short, this is looking bad."
