Take the test, pass, don't worry about it for 2 more years!

Took my 1984 500 SEC CA model with 164,432 miles in for it's biannual prostrate exam (smog inspection) and once again passed with no issues.

This year was unique. My SEC had been selected to test at a TEST ONLY or GOLD STAR test station due to the selection process done here by the State of California. Not sure why it was singled out but guessing it is due to a high number of like year/model failures recorded here.

Smog Inspection Report
Results for 06/2009:

CO2..O2... HC PPM CO(%) NO(PPM)
% %
Test MEA MEA MAX AVE MEA MAX AVE MEA MAX AVE MEA
15mph 11.5 4.6 120 41 41 0.76 0.13 .28 1074 399 496
25mph 11.8 4.1 95 29 49 0.56 0.11 .26 904 332 378

Results for 10/2007:

15mph 14.9 .04 120 41 38 0.76 0.13 .13 1074 399 490
25mph 14.9 .03 95 29 24 0.56 0.11 .13 904 332 381

MEA=Measured MAX=Maximum AVE=Average

RPM for 15 MPH test was 1295
RPM for 25 MPH test was 1251

The attached link is much easier to read than what I tried to insert above.

For those that understand what these numbers mean in regards to engine performance and tuning (I don't), feel free to comment on my engines settings and what I could do to make it better.

The only things I have done between tests as far as the engine is concerned is new Kingsborne 7 mm wires, NGK plugs (5's), oil changes and air filter and the replacement of the stock main cat with a 49 state cat (single flowmaster). I have a Magnaflow resonator and Magnaflow stainless muffler. Did an "Italian tune up" just prior to taking it in for the inspection.

I was unable to watch the inspection so I have no idea if his visual included looking at the cat up close and personal. He did not place the car on a lift so I doubt he could make out what cat was on it.

So long story longer, I guess it does not matter if you are running a 49 state cat for the California smog check. Don't forget to comment on how to get my numbers better!

Cheers,
Greg

JMO. You need to have the CO set and fine tuned by your Indy...or yourself.

Great that it passed. I know how it feels when it doesn't. The Blue Bird failed because of the Evap test and none of the other...Go figure! Next time she passed with lower numbers than before due to a CO and fine tune by the Indy.
