Re: failed smog :-(

[Jeff Enderwick <tje@domain.elided>]

Ok - here are the details:

          idle           2500     (max allowed)
HC(ppm)   124/(100)      56/(130) 
CO(%)     0.10/(1.00)    0.23/(1.00)
CO2(%)    16.2           16.6
O2(%)     0.6            0.1

Didn't get any NOx numbers.

Thanks!

Jeff
