Just get any of the codes tuned out when you have the car tuned and you won't have a problem with emissions. All they do is hook into the obd 2 port to make sure your computer isn't throwing any codes.

so they dont actually put u on the dyno anymore?

Nope, they had all kinds of problems with that. At least that's what I've been told. I haven't had to go in a long time. Hopefully someone else can come in to confirm this. I suppose you could always call there.

yes, they discontinued the use of the dyno (IM240 I believe it was called) due to the lack of cars that were still OBDI. it costed more to keep the equipment operational than the state deemed justifiable. As far as I remember OBDII cars have never had to run on the dyno and have always just had the OBDII system checker plugged in and a fuel cap pressure test done.

I'm battling emissions as we speak. Don't be so sure. They check the readiness of the sensors so you cannot simply just turn everything "off":quote:

Also, if you have a custom tune, and your rear 02's are turned off, odds are you are throwing a P1000 code (system ready check). I drove on my custom tune for an extended period of time and the code never cleared because it could not complete the readiness check.

Quick way to tell if your car cleared the readiness stage is scan it with your SCT if you got one. I also, 99% sure, believe that if you turn the car ON, and there's a CEL that means it tossing the P1000, this CEL should go away once you start up the car.

fwiw KNOW what you are doing before getting tested, you can try being tested a few times but after 2-3 tries you get locked out of the system and need a signed mechanic notice to get retested.

correct on all fronts. OBDII cars never ran on the rollers or did the tailpipe sniffer. OBDII cars only get the diagnostic port check and the fuel cap check

now if your tune is "shutting off" the O2 sensor codes, it may show a "not ready" status of your O2's when they test it, in which case you would not pass. just a heads up

you beat me to it lol

you beat me to it lol

It's a bitch, lemme tell ya. car is stock tuned and running on a smaller pulley and has been nothing but 3 weeks of PISSING ME OFF

Also you are allowed 1-2 not ready's depending on your year car I am told.

this is not correct. The CEL comes on when the car is first started as part of the prove out of the dash indicator lights.
All of the lights should come on either when the key is first turned on or when it is being started. They stay on for varying amount of time. That's how you know if they are working or not.
