As a followup to yesterday's 6 month update:

I just got my bi-annual emissions check-up.  Very much painless compared to
last time.

Here in Albuquerque, the following standards apply:
Hydrocarbons:  220 ppm
CO:  1.2%

Two years ago, I failed with the Wasserboxer on the first and second try -
the Dealer finally was able to pass the car with the following readings:

HC:  Idle=217ppm; At speed=85ppm
CO:  Idle=.06%;  At speed=.53%

I uderstand that it took a "severe" warm-up and a few tweaks to make this.

Today with the Eurospec:

HC:  Idle=12ppm;  At speed=45ppm
CO:  Idle=.01%;  At speed=.05%

I'm happy!
