The CA ref said that I have slightly too many hydrocarbons in my exhaust. How can I get rid of these? I did an oil change and changed my spark plugs before I went.

Also he said that I have to remove a fuel pressure regulator that isn't even hooked up. Can he do this (I'm guessing he can do whatever he likes)?

 

When was the last time you changed your cat?

And yes you have swap the regulator for emmissions, just swap it out for the stock one. Use the adjustable regulator when your going to run, if you get your hood poped by a cop he will sent you back to the ref and pay a fine.

 

what kinda numbers were you putting out?

i would do a regular tune-up and swap out the cat for a new one or one in better shape or lower miles.

btw: an adj fuel pressure regulater, adjustable cam gears etc are illegal and they will fail you for it...like what the other guy said..swap it for a stock one, pass ref then put it back on (if its really necessary)

 

Can you post up your smog report or do they not do that here. Yes, you have to remove the fpr they are not allowed in Cali. I was wondering what kind of numbers I needed to pass.

The FPR was not connected. My stock GS-R one was connected.

I dynoed once at 361 whp, 239 torque and 357 whp and 243 torque at around 8800 rpms, 11 psi (no 3 BAR map sensor), 91 octane.
I bought the cat from a member here on HT. It seemed in pretty good shape.

 

does not matter no visible fpr just remove it and put it back on if it is not connected

 

a tune-up will not reduce HC emissions whatsoever. new spark plugs won't either. unless your current spark plugs aren't even giving spark. was carbon monoxide (CO) absolutely zero? if so, i think that is a good indicator your cat is working. or maybe if u put on your stock fuel pressure regulator your car will stop running rich? either take your car to a friend that has a smog analyzer or take it to a licensed smog technician to get it done correctly. just don't blow your money on a tune-up like i've seen so many failed cars do with no change in their result. i'd know, im a smog technician. unfortunately, i don't have enough experience under my belt to tell you exactly what it failed for by just looking at the results.

PS - the fuel pressure regulator plays a BIG role in the resulting HC... HC = unburned gas. if fuel pressure is higher than usual, then you definitely will have excessive HC. if fuel pressure is too low, you'll run leaner and have less HC. you def need that stock fpr hooked up

 

do high-flow cats pass smog?

 

My hydrocarbons at 15 mph were 104 with the max for passing being 60. CO% was .02.
