I installed a TVS 1900 back in March and I'm due for my first smog inspection next month - July.
I've been sweating passing the visual. Otherwise, the car is basically stock from an emissions standpoint.
I'll see how it goes.
Phew...
Passed without the least bit of trouble.
Good numbers too.

i know this is a super old thread but, whats to prevent someone from flashing there car back to stock just in case the smog computers can detect tunes, and driving it down there and smogging.
as long as you keep your foot out of it, IE limp the car down there, basically any set up can run the stock tune and as long as you have high flow cats you won't throw a code so you should pass the smog test.
then reflash your dyno tune when your done and your back to the fun?
sounds like the new smog laws in 2013 will be easier as long as you flash the stock rom on it before you tune. and for those with very aggressive set ups you should still be safe as long as you keep your foot out of it till your smog is over right?
dyno tunners wanna chime in and say what you think since your the computer experts?
1st they can't detect tunes. Many CARB approved devices come WITH a tune.
2nd if you flash you reset all the system checks. You will fail the ODB2 test.
3rd not any cars can run on the factory tune. Many use larger injectors and it wouldn't idle right. Also a large cam can surge like no tomorrow without a tune.
Yeah I was hoping they can't detect tunes. I'm deciding whether or not to go with a cam as I'm full bolt ons now. So before I get a cam I wanted to be sure before I get a set up that wouldn't run on a stock tune if I had to.

Dan,
#1 I was reading that the new system will check the "database" for your VIN to see if any parameters have been changed on your ECU and for CARB tuning like the CARB legal tunes that come with the MP112. I've seen this on a couple other websites and on the CARB manual for performing the tests. Just wondering. It also states that any parameters such as rear gear ratios, transmission changes or anything that has been changed on the computer will be detected and marked as a fail. If I'm missing something please let me know.
#2 Yeah relating to #1
#3 Totally understand this.
If this is a repost I apologize and will take down my post.

This would be a nightmare...

that cant be right. gear changes have zero to do with anything in the way of emissions. That's like saying you'll fail a smog test for having an aftermarket radio installed.

I was reading that it's in the operations manual for teaching new smog techs. If you have a completely stock A4 GTO but change the shift points that you will fail because the ECU codes don't match the ones in the database for you VIN.

I was thinking that too but it says rear gears would be detected if you changed the speedometer to correctly reflect the accurate speed after the swap. again I read all this on the CARB website
Hopefully more information will come out as guys get Star tested.
If what I read was true it would fail 90% of the GTO owners I know and how would we get the stock mapping back into the car if we wanted to? I'm trying to be patient Dan.

This is horseshit. Sometimes the same exact car can have different tunes from the factory. Half the time the smurfing dealers dont know what is supposed to be in there.

Yeah I think we are giving the OBDII test and "database" a little more credit than it deserves. I find it hard to believe that they would be building in EVERY SINGLE ECU setting for every single car made after 2000. Previous smog checks where not even able to detect timing settings as you could advance or retard timing as needed to control NOX. I used to smog my 99 corvette with the laptop in the passenger seat, aside from having to take a drive thru town to reset the monitors after a flash it was cake and the smog guy never knew the difference.
Now the new OBDIII stuff might be capable as it would have been designed from the get go to do it. I'd think it may store the factory calibration within the ECU forever, then the smog machine is merely comparing the current tune with the one stored in the ECU. Thus eliminating the need for the "database" of all cars since 2000, each car carries it's own factory tune on board.

Think about it, every tuned car in CA would fail...gm,ford,dodge,etc.... Every speed shop would go out of business... All you could ever do is a filter and catback.... Talk about killing car sales.

Read this on another forum from a cat that had to have his 2005 car smogged today...

Just came back from smog test, literally.
Talked to the tech, he said the non-sniffer test won't start until next year.
However, they've renew their smog test system (Star system) staring this month.
Making sure the techs are doing what they are supposed to do instead of cutting corner.
And required to get the new machines for the non-sniffer test (OBD2 only) later this year.

so one of my questions is will the stupid cost of a smog going to come down? I remember that being one of the selling points. Yes I know nothing run by this State gets cheaper stupid question
There is a CVN (calibration verification number) and a relationship between the pcm id (software part numbers) and the mathcing CVN. This could be checked, and would make your "tuned" pcm fail.
I hope it does not come to that, but that technology has been around as long as the OBD2 pcm has been for GM.
