Would anyone have a graph, or at least numbers I can use that shows the voltage output of a stock honda narrow band o2 sensor? I'm using my narrow band for the next few days, and the readings I get from it are way off.

 

thats cause it sucks

 

Hook up an Apexi Turbo Timer and use the voltage function.

 

.9 volts and above is good->rich, below .85v you could be running into lean conditions. I believe .5v is stoichiometric, however, the scale is not linear (at all!) and ramps up very quickly right around the a/f ratios we are looking for...
