Does anyone have any ideas for testing our exhaust gas emissions, that is reasonably affordable? As we modify our engines to get the best mpg, we also need to be sure, what we are doing does not alter emissions for the worse. I was wondering if we can get away with just testing the O2, as it seems it goes up as CO2 and NOX go down, up to about 18/1 air-fuel ratio.
