passing emmisions with obdI conversion and turbo i CO
 

Hi guys today i went to do emmisions on my sisters car 97 jeep grand cherokee and i though it would be fun to eperimet so i took some picks off a comb and plged up the obdII diagnosis port, i watched the guy try to hook up the scanner and the computer gave an error mesage anyway they let the car pass anyway well here's my question does this mean im in the clear when i get my turbo setup on my 98 civic with a p28 ecu or what? i though for shur they would have failed the jeep,,, does anyone now all the emmision rules for Colorado? tried searching but that just fucked me

Around here (in MA.) when they check the diagnostic port, if it sends back an error message they hook it up to the "dyno" and sniffer to do the tests and see if it passes. Maybe it's different in CO.

Scan Port is not required in Colorado. As long as you pass the dyno sniffer you pass period. I just did my Civic a couple months ago and passed with fastpass. That means it beat the requirements in the first 30 seconds and that was it.
Good Luck

Emissions in NC are done on a county by county basis. The majority of the "hardcore" emissions counties are just focusing on OBD2+ vehicles, '96+. You HAVE to have a working OBD2 scanport. You HAVE to have NO CELs. You can have two readiness codes not set, but no actual CELs. Otherwise they give you thirty days to have the car fixed, or your registration is suspended, and fines out the ass.

Older cars get a visual inspection, but nobody cares much about those since they are all dissappearing... (at 15 years old, 95% of cars are still on the road, at 20 years only 15%). I've gotten inspection stickers for open downpipe turbocharged no-cat pre-OBD2 beasties recently.

Thats a givin. In Colorado you can pass with your CEL light on. That change was made a couple years ago. They don't care about which OBD system you have. They will go to hook up the scan port if your car is OBD II. But they won't fail it if scan port doesn't register. In weld county you are not required to have an emmisions test at all. So if your that worriedabout it, find a friend there and register it under their name.

I dont know where ur from in colo but if ur cel comes on they dont pass it till its fixed
weather it passes or not. i just recently took my car in for smog, CEL comes on no pass, reason being was the way my head and timimg was set to acommadate the cam i was using, changed the cam back to si and reset timing and no problem

They pulled your chain bud. They can't fail you for a cel anymore. Want proof? go to cleanaircolorado.com.

Abort, Retry, or Fail?

My bad I got the site name wrong its http://www.aircarecolorado.com/
Here is the direct link to my "proof".http://www.aircarecolorado.com/check.htm
And if your as lazy as me here is a quote "Effective April 1, 2003, an illuminated "check engine" light is no longer a mandatory pass/fail component of the emissions testing process. If the "check engine" light is illuminated, it is noted on the vehicle inspection report each motorist receives at the end of the emissions testing procedure. However, it is an informational tool for the motorist, rather than a reason for failure."
