So I was smogged the other day and although I passed I was curious as to what others have gotten on their tests as I was under the impression I should have produced less emissions than I did.
15mph 25mph
HC: 32 20
CO .22 .39
NO 180 227

Mght about half of what is legally allowable and was trying to figure out why it wasn't lower. REVI intake with ram duct, Mazdamaniac ignition. Mazdaspeed catback, and stock cat. Denso iridium plugs have about 30k and probably due to be replaced but was all I could think of.

Are these numbers about right?

 

I got
15 25
Hc:3 4
Co:.02 .07
No:1 2
17k miles

This was prior to my coil upgrade.

 

Interesting. My car has 85k but my engine and cat have about 30k, catback has about 20k. I guess maybe I can chalk it up to old plugs since my numbers are about 10x yours.

 

subscribing...
I know two guys in SoCal who recently smogged their cars, maybe I'll get them to post.


P.S. what the heck is a "mazdamaniac ignition"? Do you mean the BHR Ignition?

 

No, this was something someone else made a couple years back. They had a horrible service rep and went out of business but this was the ignition kit everyone bought before BHR.

 

do you mean Mazsport?

 

OK i smoged month ago failed once passed 2nd time.

1st time was RP supercat 2 years old Gross polluter FAIL

HC CO NO
15mph : 364 .3 1923
25mph 208 .18 1723

Stock Mazda Cat with like 32k miles on it left outside not covered under trees.

HC CO NO
15mph 0 .02 15
25mph 0 .01 127


pretty much i know my RP as catless because i cleared it out with rebar and sludge hammer. hope this helps people.

 

Resurrecting an old thread of mine. Was smogged a few weeks ago with much different results. Of course since then I've replaced the engine, cat, ignition system....

15mph 25mph
HC: 9 9
CO .11 .18
NO 4 3

Quite a difference I'd say.

 

My results (original engine):

2010, 32K miles

Code:

            15 mph     25 mph
HC          0          0
CO          0.06       0.07
NO          0          0
CO2         14.9       14.9
O2          0.1        0.0

2012, 62K miles

Code:

            15 mph     25 mph
HC          1          0
CO          0.01       0.15
NO          9          8
CO2         15.0       15.1
O2          0.0        0.0

I was surprised about the huge jump in NO emissions (does that mean my cat is failing?), but the rest appears to be OK. Everything is still way below the passing grade.
