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.

/twospoons

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 ....

In CA that may work for the emissions test part but you still have to get past the visual. I still can't figure out how the inspection stations out there can tell if certain parts are stock or not. Down here as long as it has an engine in it the guy at the inspection station has no clue what it came with. I could throw a 4 cyl in an RX-8 here and no one would have any clue as long as it said Mazda on it.

Put it this way. Played around sum w/ the emanage and took away sum excess fuel at idle. It idels at 15:1 now. I passed emissions just a few hrs ago. Yes, the turbo can pass emissions.

here in austin, as long as the check engine light isn't on and all your lights work then you will pass..... they dont really do a sniff test on cars that new, just plug into the ecu and if everything checks out fine then you pass.

we had a few 350z's that had hks f-con's and they had no problem passing inspection once the check engine light was reset.

For California, you must reset ECU and drive like a grandma. Take it in, and you should be fine. Here is the dealio... they run your car up to 3500RPMS just enough to tick on boost... but, the ECU wont throw a cell right away if your car is rich... it has to see the condition for awhile.

Or wire the wastegate open and be done with it.

As far as the visual goes... engine covers are your friend. And if they get real feisty, just tell them most rotory engines come turbo charged... and worst case, join a club in your area and find someone willing to overlook the visual.

i know a buddy that couldnt pass emissions and he got a "$200 smog check" and they passed him no questions asked...so if your willing to pay the money and find a place that will do it.

Hmm .....

this is very interesting ....

Damn, now Im preparing about 15K for the whole project, Im not really "into" turbocharged, I still like Supercharged better for some reason.

Anyway, money should be ready, and Im just going to wait and see who can have something to show the world first. (Wheres Hymeeeeee? and Richard ?????)

Oh by the way speaking of SC, what happened to Blitz ? They got the SC like what, 1-2 years ago in Japan but it has "yet" to show in USA? what the.

I know this thread is a zombie, but has anyone tried to pass the sniffer test and can compare the results with a stock engine regarding HC, NOX, CO etc?
Beside the problems with errors in the ECU and running to rich, which can be solved, how far is a turbo charged renesis away from the allowed limits? As far as I know no one ever tried to pass the euro 4 test in Germany with a turbo charged RX-8. But I am asking myself if this could be done and when someone is crazy (and want to spend the money) enough to try it.

a properly running turbo renesis with good tuning will pass in texas. it just needs the right codes blocked and all the redyness moniters ready.

dang, I just re-read what I wrote like almost 10 yrs ago rofl

a lot has changed ...

to the question (fuck I'm answering it back to myself), as long as there is no visual, YES you can pass the test without any issues. u just gotta tune that sucker's ECU + a working cat.
