|
|
Last month, I received notice that the 85 needed emissions testing and with only a couple of months from it turning 25, i figured what's the point, especially, since it will fail anyways. So, i called up the Dept. of Ecology and asked them if they could waive my car and let me get tabs now instead of letting the car sit untabbed. The guy took my VIN and a few minutes later called back and gave me the go ahead. I thought that was pretty cool. Now it's time to remove the cat and be completely emissions free. _________________

I just took the emissions test on my '87 on Saturday, and it passed.
I now plan to take the cat out! I thought I would have to put it back on one more time, but maybe I can do this too!!  _________________ -Donald

| Chip can help a lot of stuff get past. Had nothing but trouble running stock or near-stock chips and passing emissions. As soon as I messed with timing tables it passed like a champ. |

Hehe you should add more timing then.
One of the best tricks to pass emissions is to retard the timing to get a more complete burn from an emissions standpoint, not as good for performance. _________________ A redline a day keeps the carbon away! |

The trick for that particular engine (which had obviously not been reading any books ) seemed to be advancing idle timing, while retarding cruise timing, that gave the best idle and roller emissions numbers.
Of course as soon as I passed, that chip came straight back out.  |

I have no emissions gear on the Camaro and a hollow cat and it passed last time just barely. Wonder what it will do this year.  |

if you let the car sit without tabs for one year, go in a couple of days later and buy the tabs...they only inspect cars during their required years. _________________

I bet. The cops up there don't care for people who own cars. _________________

The Camaro has been sitting since January so perhaps I can wait a bit longer.  _________________ '86 Trans Am - 5.0L TPI - LT1 cam - 700R4 - WS6
