I would like to put an A/F ratio meter in my 81. Not a permanant mod to the dash or anything, something I just can use to help verify I'm running where I should to be.
It is my understanding that the meter just monitors the voltage from the O2 sensor and uses pretty lights to display the results... Can I just pigtail my current O2 sensor with a multimeter or with the Summit Gage below to monitor my ratio? What is the voltage that would correspond to a "good" A/F ratio? I've read 0.45V?

Thanks! Not long before Roxy is back on the road and I want her running right!
