Emissions Question
#22
You can pass the actual emissions test w/o a cat if there's no visual. I was asking for the numbers on the actual results sheet. Those numbers tell you what you need to do to pass. My old protege would fail at stock timing, so I backed the advance down to 2* and passed. If you're that close, something little can mean the difference between pass or fail. With a programmable ecu, you CAN tune the car to pass as-is.

Yeah. Well, I'm just trading for the Jackson High Flow cause it's free, put it on there, fixing the tune to pass, and going back and passing.
Every place in my county does a visual check for the cat, even if they have to put a mirror under the car. Evidentally there was a huge bust on the local testing shops recently, that's what I was told anyway.

Well, they did 2 tests, a 25/25 test (25 pounds of load at 25 MPH) and a 50/15 test (50 pounds of load at 15 MPH).
Here's the results:
HC-ppm - Pass (25/15) Fail (50/15)
CO% - Fail (25/15) Fail (50/15)
NOx ppm - Fail (25/15) Fail (50/15)
I can't remember the numbers exactly, but I do remember that everything was just above the allowed limit, except the one thing that did pass, and it was actually well under the limit.
