Can Turbo Pass Emission test ?
 

I did tried to search but cant find anything related to this.

Anybody here, whos in an area that requires emission test every year with Turbo 8 ?

I know that every state has different emission standard some dont even cared!

Why I ask ? because I dont think I can pass NYS emission test if I turbo my 8. (Yes Im looking to Turbo my 8 now)

Thanks!

It doesn't pass CA because there is a visual. There's no reason a well-tuned turbo wouldn't pass a sniffer test.

Depends on the county...

Aren't most states using OBD? Wouldn't that give up the turbo?

only if you have a CEL

i think maybe if you slipped the guy a benjamin then it would pass

.

Well in New York City you have to do your first Emission test on the "3rd" year of a brand new car (meaning I still have 1 year and 2 months) and yes, you HAVE to do it every year.

So, to those who have Turbo and HAVE to do emission test. No CEL for example. can you guys pass the test "NORMALLY" ? If not then, what you guys do in order to pass the test ? (I know you have to pass it to be able to get the window sticker, and please dont tell me about giving the tester bunch of Geroge Washinton bills before he let you pass, Im talking about LEGAL way)

Disable the turbo for a while and let it go back NA or something ?

couldn't one just leave the wastegate open so it doesn't increase boost? i'm sure it'll pass w/o any boost. or maybe some kind of a lock for the turbine shaft. i of course base this on absolutely nothing.

I have no idea how Turbo/SC really works since I never had owned a Turbo/SC car before. but ever since I got my 8, and I read this forum I learned quite alot.

As far as I know it produce much more pressure (duh) and it might pump out more "bad smog" than usual.

Just wondering did ANYBODY here can PASS emission (any state) with their Turbo on ?

If not ... what you do to disable the Turbo so you can "run" the test ?

I really need an answer before I jump onto the Turbo/SC group (Theres Awful amount of Traffic Cop in NYC, Thanks to Boomberg, the result is that you can get a ticket for Inspection sticker within 2 minutes)

you should pass the test at idle since you are not on boost, your turbo won't even be working.

If it's tuned right and you still have a functional cat, you should be able to pass. I'm sure if you have a boost controller, you could make a emissions tune and pass it easily...

There are companies working on ECU reflashing. What if you reflashed the ecu so that it was looking for the richer numbers and what not, anyone think it could pass then? They use the OBDII ports here in GA. So if the ECU was looking for the richer numbers and thus didnt have a cel then maybe it would pass

Well, I'm in that situation here in NC. I think by just subtracting sum feul at idle, so it idles leaner, then unpulgging my battery so the CEL goes away will get me to pass. But, that what I'm gonna try, and if that fails I'll have to pull sumthing outta my ass cus my inspection was due in FEB, so I have 4 more months until I get a 250 dollar fine! :eek:

If you pull the battery then it clears everything but you have to have enough data in the system of you will fail anyway.

The car runs pretty lean at idle now. If you lean it out anymore you may find it unwilling to idle properly. You actually need to richen it up to get a smoother idle. If you have no porting, there is no reason why you would need to lean it out at idle. It shouldn't read any different than it does stock. In some states such as here in Texas, as long as you don't have a CEL, you pass. Easy enough. In other states you do need to pass a sniffer test. The test loads should never be at a level that requires boost so again with no porting it should pass just fine. The maps only really change the mixture under boost. For the most part the vacuum/light load maps stay essentially the same. If there is a test that puts the car under a small load, then it may or may not be necessary to wire the wastegate wideopen. No boost, no added fuel. Simple. The only time I see it being an issue is if you have a visual inspection that needs to be passed as well. Here in Texas they don't care what's under the hood as long as it can pass the testing computer's standards.

Don't sweat it. It's fine.

From what I've read it seems like the interceptor-x always gives you a CEL since the ECU detects that it's running too rich .. So it beats me how you can pass emissions without reprogramming the original ecu.

Unplug the Interceptor, reset the stock ecu, leave the wastegate wired open. go get it inspected. Go home plug the Interceptor back in and unwire the wastegate. That's all pretty quick and easy. On my RX-7 I have to reinstall an air pump and a cat every year just for 1 day.

fortunatly for me there are only about 8 counties left in Ohio that need a emmissions check. Unfortunatly I live in one of those counties but the program is phasing out anyways. The ohio government is finally growing a brain on these worthless emmissions tests.

i live in nc. too and just got my inspection done. i removed my battery cable to get rid of a cel and took it in with no problems. most places i have been to dont do a visual so youshouldnt have to worry about that. most wouldnt know what they were looking at anyways. good luck.

I think Allegainy County requires emissions once a year...same as Beaver County. Last I knew, Butler County didn't require them...unless I'm all mixed up.

Ok, here...this FAQ covers questions regarding the counties NOT requiring emissions. There is a list at the top.

I was concerned about going FI on my 8. CA has some strict smog instpections. They do a visual, sniffer (they stcik a device into the exhaust pipe), and they run the car up to speeds of -/+30mph. So just as long as I disconnect my after market EMS and rewires the wastegate I should be good. Ohh and of course when I do go FI I will keep the stock parts (someone on here has a FI but you can't tell unless you start removing covers) so it doesnt raise a red flag to the smog technician. Thanks RG!

I drove my 8 about 65 miles on the highway today after getting the new starter kit. Starts up great, and for the whole trip my CEL was gone so I thought I'd be good to go for inspection. I take the exit ramp, and am in town at this point, and had boosted maybe 5 times onthe way home just to peak at my wideband gauge and make sure all was good. Well, my CEL came back, and I'm wondering about emissions for myself yet again. At idle, the car is running an afr of about 15, sumtimes alittle more, sumtimes slightly less. Not rich at all, and perfectly smooth. If I unplug the battery to reset my ecu, and then drive like a grandma to get through the arbitrary 5 cycles or whatever that number is while staying off of boost at all costs, is it possible that the CEL would not come back on so I could pass the emmissions test??

out of curiosity, doesn't oxygen fooler dongle take care of this issue?

Yea, AKA the CEL eliminator, but I have a wide band and I wouldnt wanna have one and throw off those readings.

In NYC they dont do visual, but sniffer is a must. and they run your car to 60MPH for a few seconds I think.

So dunno .... maybe if I go turbo/sc then I can just unplug piggyback, open the wastegate ALL The way just to get the new sticker ....
