Well i failed my first try Here is what i got....

%CO2 %O2
14.0 0.4 15mph
14.8 0.0 25mph


HC (PPM) Max GP Meas
95 286 256 <U>Fail </U> 15mph
60 236 174 <U>Fail </U> 25mph

CO (%)
Max GP Meas
0.58 2.08 0.85 <U> Fail </U> 15mph
0.57 2.07 0.22 Pass 25mph

NO (PPM)
Max GP Meas
726 1981 2020 <U>Fail </U> 15mph
786 1781 457 Pass 25mph


What do you guys think is the problem ? Or what can i do to fix it ?

I have all new Cat, new 02 sensor, & new ngk v power spark plugs gapped at .44.

91 octane, fresh motor oil and try it on a cold day

pump up the tire pressure to get less rolling resistance on the roller.

I use Chevron 91 octane all the time & Mobil 1 Full Synthetec 10w 40 Oil. But what Psi should i go on the tires ?

You might retard the timing.

Dc4iNtEgRa

I ran 87 octane, and set my timing to 14... Passed the first time.

Did you have to switch to obd1 to get the car bar'd.

My timing was near 16 degrees, yes i converted my car to obd1. I passed the visual inspection, i just failed smog.

Dc4iNtEgRa, what spark plug gap did you use??

MIGPA26

I was thinking of changing my timing to 14 degrees also, Im using alot of fuel.

Is it hard to go from a obdo to obd1 .

I was told to get a ecu wire harness, dizzy, and new ecu

Just a thought...

You stated you have ITR cams in there. I'm not technical enough to state that the cams are you problem but it'd be the same thing (in theory) as putting aftermarket cams in a stock motor. Let's say you had another motor, would you go to get it smogged with a set of aftermarket camshafts installed? Again, just a thought. Maybe the ITRs are close enough to stock B16A cams but who knows. Maybe the TheSmogMan will chime in...

I gapped them at 0.049.... Specs for a DelSol B16a3 are 0.047 - 0.051...

P30-A00 ECU
ECU jumper harness *Depending on REF, Some don't like them.*
OBD-1 Dizzy *B16 or GSR*
OBD-1 Throttle body. * I passed with a GSR, But the nipple for the Charchol canister bent to the left instead of bending straight up. Needs MAP sensor*
OBD-1 Thermostat housing *Again depending on REF*
Electric VSS *Again depending on REF*
DATA LINK CONNECTOR *Again depending on REF*

I had the thermostat housing, so I installed it and extended the wires from the back of the block. When he and 2 students were checking out my car, they didn't say anything about the VSS. One of the students said my car was missing the DATA LINK CONNECTER, and the REF said 98% of swaps don't have them. I went to Santa Rosa JC to get reffed, and the guy that REFFED my car was from Alameda.

I'm here... I was just waiting for the other suggestions.

What the OP forgot to post is the O2 readings. Just want to see if it was warmed up enough first. So we need these numbers!!

All of the numbers are up at the 15 part? Hmmm. and the only one that failed at 25 is HC.

I am not at all experienced with cams however they will raise the numbers. Are the cams set at 0 or have you tuned them? Might want to take them back to 0. or back to stock for the test.

New cat??? Is it....hi flow? stock? from what motor? Need more info!

With those cams you would not want to run 87 I believe, however 87octane burns cooler and it is easier to ignite. Might lower the numbers a bit for HC because it ignites better and for Nox it burns cooler. You might be able to get away with it with retarding the timing like was suggested to 14btdc if your spec is 16btdc. Two degrees will lower the nox numbers 150ppm's or so.

So there is some info, let us know what the 02 reading was please!

Yes it's a new cat & the guy said it was good to pass smog. I din't care if it was a High flow one cause after i got it Bared i was going to take it out.

Janos Lin

Why? You're gonna have to get it smogged every 2 years, and if they catch you with a roadside sniffer, thats a ticket. The HP loss from a properly functioning cat will hardly show up on the dyno.

Get the right camshafts, ITR ones are too aggressive, and intended for a bigger motor than yours. 87 octane would be a good idea also.

Seeing as how Skunk2 stg 1 cams (pretty much the same as ITR's) are smog legal, i seriously doubt the cams are the root of your problem.

143MYVTECEF

i barred my LS with crower 403's so i doubt the cams are the issue but hey if you got a pair of b16's laying around throw them in there and retest

thesmogman

Well see... if your cat is a hi-flow it is designed for "Duh" hi flow. It is also designed to just do enough to get you thru. If the motor is at all modified you run into problems like the cat not reducing enough. Now if the tech is fimiliar with hi flow cats then that is another story.

I still didn't get the 02 numbers yet! If you were above 0.3% at 15 then I would check into a stock replacement cat that you can bolt in and out.

I didn't think cams were legal. since we can't check them I didn't even think about them. But you are correct cams are legal and if they are comparable you should be fine with the cams.

Skunk includes a carb sticker if u buy their stg 1's.

Are you sure you're using the right ecu?

mackadocious

take it to long beach ...they could pass you for 120

atarigamer01

Another thing also, I used to have an integra and I remember I took it to one smog place that didn't pass, but it wasn't a test only :/ So, I took to another place that was a test only near my work and it passed. Barely, but it passed. Maybe try another place. Sometimes the little hole in the wall places are actually the best.

Yea it is i bought it from some guy from here. It's the U.S P30 delso ecu.

where did you go? Riverside or San diego?

THANKS INFO HELPS..

But do I really need to convert to obd1 to get it refereed

Im going to modesto junior college.

Yes you do, since the first B16 was intrduced in 1994.
