State emissions

So anyone living is californish states with emission laws.. as in strick ones?

Going to washington soon, and of course they have, well I won't say strick but real emission laws. Two year emission testing and all.

Question is, when I start building up the lq9, where can I get the info to know performance wise is too much when it comes to passing emissions? or will my ecu be capable of keeping it within limits of what is legal? I want the power.. but I want to be able to drive it too. More than just the track.

When you say strict emmissions...does this mean that they stick sniffers in the tailpipe on your truck? I know Texas has some decent emmissions laws, but that also depends on the year of your vehicle. Most vehicles with OBD-II are just have to use a programmer plugged in to read everything--which is good for us that have a tune. But some may use a sniffer--and you will not pass those without cats...even a stupid big cam with cats may not pass emmissions!

From what I know all obd2 95 and newer just get put on a computer in washington. obd1 and non obd get visual check.. so I guess there is nothing to fear.

Just gotta make sure I don't crop dust them when I get it tested:LOL:

here in the great state of TX, if you have OBD1 they throw your vehicle up on rollers and put a sniffer in the pipe to check the emissions levels. That is if you happen to be lucky enough to live in one of the larger metroplexes that have emissions testing in addition to safety tests.

Ways around them all. Not going into detail, LOL. Just become good friends with a mechanic.

My 408 legally passed here in Texas, in an emissions county.

Yeah, only a little over a year. Persitence pays off!

so for the most part. obd 2 just gets tied to a computer? So forums, good mechanic friends, and google will do the work for me.

As long as the dont look under the truck. But you can put ''race'' converters on. I pulled into a oilchange place resently to see if tey would inspect my truck after the cam... he said as long as the CPU give it a green light, Im good to go. The lope doesnt matter. Some places will get out the book on you and fail everyone.

Where I live in south FL. there are no emmissions testings.

Funny how close I am by freeway time to RedHeartBeat yet anything goes here. Too bad they make you show address of insurance when you get tags...and the address on the tags is the county and the rules you get tested by....

Eventhough I don't have to have the sniffer, I want cats because I don't like the smell on my daily driver!

Eh, the smell isn't that bad. My friends joke with me and ask if I drive a boat...cause my exhuast smells a little gassy at idle--but then again, it is because of the cam...

Im assuming even though I have the newer engine in my OBS truck that it still goes by the yr of trk?

If thats the cause I live in an emissions county and it has to go on the rollers for the two speed test. :(

I guess I have to look into cats.

So do ya'll guys think a stock LQ4 with a tune with pass the sniffer with no cats?

I think it will pass everything but the visual inspection. The Gen3 engines are very clean running. :rock:

Fo sho. Greg is right--GM engineered the GenIII motors to run at a slightly higher operating temp--so that they could burn off all unwanted gasses. You should be good.

Visual would require all the emissions equipment from the donor, including all the EVAP crap.

Evap can be fooled by using a dummy setup. 2002 Camaro had hardly any emissions stuff other than cats, no EGR too.

This 2002 T/A I have here has AIR though....what a pain.
