Took the car today to get it through emissions.

Mine Limit
Hydrocarbons: 2.97 1.00
Carbon Monoxide: 48.18 12.00
Nitrogen: .28 2.50


Car had stock cat in, Air pump routed straight to cat.

AFR's are around 12s at idle leaning out to 14s by 4000rpm (in vac of course)

Car does stink when standing behind it. Whats the next step here? I have absolutely no idea how to tune on the PFC. I borrowed this cat because I was told it passed.

My next line of though was buy two universal cats and have them welded into my straight-thru midpipe. and throw in a gallon of alky.

This is DUMB.

I had a hell of a time trying to get mine to pass..I never got it to pass. I had to get collectors insurance. And i have stock motors and stock sequential turbos.

Off topic, I would be interested in seeing the dyno numbers on your build. I have been talking to Glen at AZRR about a future streetport motor.

I made 267 whp on wastegate spring pressure, about 9 psi tops. Boost controller broke before we could do more. Its got ALOT more in it. Have Glen do your engine.

IMO, it sounds to me like your stock cat may be fried. I didn't see anything in your AFR readings that a stock cat shouldn't be able to handle. Did you thoroughly warm up the car (and, of course, the cat) by spirited driving before the test?

Move to NC where anything pre 95 is a safety inspection only, they don't even look for a cat (good thing because I don't have one)

How hard is it to get a street ported motor to pass emissions with the PFC? Is it possible? Even with the right tune? I know UMS does a great job tunning. Maybe give UMS a call and see what they say. Maybe he can detune the car. Did you go to the counter after the emissions test? They can give you ideas on whats wrong.
You borrowed someone elses stock cat? I cant image that its still in good shape.

Short story about Az emissions testing.
First time I tried to emissions my FD it failed. (bone stock FD). I went to the counter and asked the guy what the problem was.. He basically told me it was the guy who did the test. The driver gave the car way to much gas. They are horrible at trying to pass turbo cars. The driver even told me " WOW this car is fast". Not really what I wanted to hear trying to get my car to pass emissions.
The guy at the counter tested my car himself and got it to pass not even close to failing.

Ill try to look up my old test to see if I have similar numbers. It was 3 years ago so I dont know if I have them.

This test probably wont help you, but this is the differences in a test 20 minutes apart with different drivers.
First /second/standard(mine standards are a bit different)

Hydrocarbons 1.10 .42 .8
Carbon Monoxide 32.19 4.32 12.00
Oxides of Nitrogen .23 .55 2.00



I do have a High flow cat you can borrow/buy if you need. It only has about 4000 miles on it. Its less than 2 years old.

^ What changed between tests?

It was a different guy testing it.
I didnt touch anything.

That is so true. We tested the car about 5 or 6 times. Our second to last test I asked specifically for a tester that knows how to handle a turbo. We just barely falled that test. So we drove it around a bit and Jesse decreased a few fuel cells. We went back, about 20 minutes later and got another guy. This guy knew **** about how to drive a turbo. He fully boosted it about three times and we failed miserably, the worst numbers of all the tests.

So, the moral of this story is ask for the best tester and you will have much better luck.

I'm also thinking about adding some slack to the throttle cable so they can't go full open. Good idea? Bad idea?

you guys must have different testing methods than we have in Wa. If a tech ever went wide open at our stations I would imagine the car would jump off the damn rollers.

Maybe you could set the rev limiter really low to keep them from being able to put their foot too far into it.

last time i got my fd tested, i had to set up the damn wire and give it the gas and everything. he couldn't find the lead wire, and he couldn't keep the car at the right rpm, kept saying my throttle was too touchy so i told him to get out of the way. lol.

DaveW

There's no way you could loosen it enough to prevent too much throttle. Even 1/3 throttle will screw the test results.

There's dozens of threads on this subject, but, since I've been there...

Last year, all my seals were worn, and the FD tons of oil blow-by.

Not surprisingly, I didn't pass the first test.

So I had a muffler shop replace my destroyed cat with a Magnaflow one - which was about 30 lbs lighter than the stock one. I then replaced the oxygen sensor and EGR valve. Even with the aforementioned dying engine, the car easily passed the unfair/bs California test, legally. I do believe the new cat made the biggest difference. A street port or a 4" exhaust won't be the reason you fail the sniffer.

(I have a new motor now.)

I'm going to be looking into a magnaflow cat, but I don't know how soon i'll be able to get one.
