n/a Using a Sun MGA 1400 exhaust gas analyzer, the %CO, %CO2

Resolved Question:

Using a Sun MGA 1400 exhaust gas analyzer, the %CO, %CO2 and ppm HC work fine, but the Air/fuel ratio meter does not. Can an a/f ratio chart be made up using either the CO or CO2 gases? Or is there an a/f ratio conversion chart available?
