[s-cars] Emissions Question (NTC- no turbo content)

[Mark Strangways]

I just did my emission here in good old Toronto,
I drove back from Bellville, about 150 miles, then went home, shut down for
a short time.
Drove to "Drive Clean" testing facility, and shut down. Car sat maybe 10
minutes.

idle.
HC     limit 200, my car 75
CO%  limit 1,     my car .02
2500 RPM
HC     limit 200, my car 45
CO% limit 1,      my car .18

This is with Stromung mit cat, Lehman stage 3. Stock everything else (I
guess, can't remember).

Good numbers ? Works for me
