Anyone know offhand what the voltage for running lean or running rich is? I have my s-afc rigged to read the first o2 sensor as one of the aux-inputs for the S-afc and i don't have nice little bars.

 

Decker, 0 volt is very lean and 1 volt is extra rich,at idle and while cruising normaly the sensor should fluctuate from 0.1 volt to around 0.9 volt
at WOT you should get a reading of 0.95 to 1.0 volt on a stock car but with the SAFC you should be able to get 0.8 to 0.9 volt (a bit leaner then stock specs) remember a O2 sensor is more a diagnostic help then a real tuning tool use it carefully

i wasn't planning on tuning it using it, i was just hoping to see the a/f ratio.

i have a dyno appointment #3 on saturday to tune it.
