CALIFORNIA SMOG TEST with just a OBD port test?
Recently, I went with my buddy to get his car smogged. He has a 2003 mitsubishi lancer. All the shop did was plug in their obd scanner and did a quick visual test. In less then 10 mins, we were on our way. No probe into the tailpipe. I looked at the smog report and there seems to be no "emissions test" I know CA did some changes and i heard about the new obd scan check but I never experienced it until yesterday. Has it come now that vehicles years 2000 and up ECUs can read emissions test such as HC,NO, and CO reading through the new CA smog check OBD tool? Need more info on this.

sounds like AZ smog. I was in and out in 6 minutes and even got a reciept. I was blown away and all this with a Joe Z exhaust and a AOS. LOVE IT !

2000 model year and newer vehicles (except for vehicles 14,000 GVWR or greater) no longer require the tailpipe portion of the smog inspection.

I'm curious what the new equipment that they are using to read the ECU is looking for. Is it simply looking for the same items that would trigger the check engine light? Or does it do some sort of "deep dive" into the ECU looking for data that that nobody would ever have access to?
If the equipment is simply looking for the same items that trigger the check engine light, then this may be a good thing for ISF owners who have I/H/E being that there are no ECU tuning capabilities for our car. Theoretically, if SIM's were used correctly for header installs, and no check engine lights were on, the ECU should just tell the new equipment that everything is okay (despite haveing no cats, hi-flow cats, etc).

While I don't personally drive an IS-F, my car has CAI, Headers and exhaust. All i did was roll up and show them all my CARB stickers.
Plugged in that OBD reader, ran the test and I was on my way

semnosNSX, your theory is actually much closer to what could be the truth. While the dyno roller isn't needed for 2000-2001 and up cars the equipment may actually be able to detect reflashes by verifying the checksums in the ECU. Every time you flash any ECU this is the trace it leaves and it's a tipoff that the programming may have been changed.
So far no one has complained about not passing a smog test in any car with an ECU reflash but the technology to detect this is available. Remains to be seen what the ARB will do in that regard.
