Does anyone know what the o2 voltage readings equate to in terms of a/f ratio? I have the SBC-IDIII with powermeter, and it will allow me to enter "fit" criteria for inputs so I can have it datalog in terms of a/f ratio rather than the voltage. I need only two finite points really.

If this has been posted before, or is in the service manual, please let me know. Anything less than 3 characters can not be searched, which is frustrating.

 

Volts A/F ratio

.1 --- 17:1
.2 --- 16.5
.3 --- 16:1
.4 --- 15.4
.5 --- 14.9
.6 --- 14.4
.7 --- 13.8
.8 --- 13.2
.9 --- 12.7
.985 --- 12.1

 

Thanks, that is exactly what I was looking for! Did you get that info from the service manual? I ask because I am able to monitor two other inputs as well, and I was thinking about coolant temp and intake air temp just for fun, since the SAFC will already be monitoring the other things I would use.
