Holy .. I failed my emissions so bad..
I dont know why though, this is the first time I done emissions
its a b16
I changed air filter, new cat *the guy gave me a high flow*
pcv valve changed
changed oil.. ran 91 octan, new plugs, thermostat
hc ppm I got 162 O_O
co% 0.65
NO pp, 3918 O_O
RPM was only valid at 2520 and Dilution was at 14.20
Can someone help me out -_-

maybe you're burning oil

Ourstory

the oil is always full though X_X
I never had to top up

why not pay to have the car diagnosed, instead of randomly replacing parts?

did the car come with a B16 stock??..

Ourstory

I replaed the parts maybe couple months ago. I didnt realised I had to go a emissions test till I came back from China =[

Ourstory

nope it was swaped

Did you classifie as a hot rod??.. or stock?

Ourstory

I told them i had a swap and he said it wouldnt matter O_o

iTaLiAn_vIrUs

agreed.
Do that first before you start messing around.

or you can do it the ghetto way and do it under the table
lol

somebody told me there is no more hot rod classification.. I forget who that was. I haven't looked into it yet though.

Your NOx is pretty damn high..

Well, honestly.. just pay an hours labour to a qualified emission tech and he'll find the problem.

What ecu do you have?

Yeah I heard the same thing about the hot rod class. I have the same motor and it failed aswell in december. I also had a high flow cat, I had it checked and that was the prob, changed the cat and passed with flying colours.

allstar_6d9er

the hot rod class is still there.
it only kicks in if you changed the displacement tho.
vtec and non dont matter, but if u put a 1.8 in an eg for say it would classify it as a hot rod when they entered it in the computer.
Had it done up north as a buddys a tec and i swapped in a d15b jdm motor and he just ran it thru as a 1.8 so i had the added numbers

iTaLiAn_vIrUs

really the high flow cat was your problem??
what was the CFM rating on yours??

i just got mine installed and its 400CFM
dont tell me thats gonna give me a hassle ;s

seanv98

I don't really remember. My cat was pretty much just a straight through pipe, I doubt it did anything for emmisions.

b16a

i just did mine today
HC PPM =39
CO% = .07
NO PPM = 515
RPM = 2645
Dilution = 14.47

and the dude was telling me i was lucky and it wont make it next time ^o)

Hot Rod is still available i had mine done 2 months ago. hade mine classed has a 2 liter just to be safe and it passed with flying colours.

your NOx is really high but so is your hydrocarbon. this might point to a possible timing problem or the wrong ECU, or a combination of other problems. I gotta agree with letting a pro look at it. but starting with the correct ECU would save you a lotta hassles cuz that way you can eliminate one big concern.

Was your ECU chipped? Running more timing? More fuel?

iTaLiAn_vIrUs

well guys
i did emissions...
and yeah.. needless to say i failed


i only failed on the
NO ppm

the limit was 550 ... i got 868

IMO i think i know what the problem is... i have a AEM cold air intake.. and i have advanced my timing..

BUT it could also be

- Inoperative/ineffective exhaust gas recirculation (EGR) system
- Excessively lean/air/fuel ratio (i stated this before)
- Malfunctioning or missing catalytic converter (this has been replaced)
- Excessive spark advance
- Faulty thermostatic air cleaner system
- Engine deposits or mechanical defects
- Faulty cooling system


what do you guys think??
