O2 Sensor Voltage to AFR
Is there a way to convert the voltage from the O2 sensor to air/fuel ratio?
I just got a tune on my car and everything seems fine, but I'd like to see my air fuel ratio. I have a bluetooth OBD2 transceiver that I use with the Torque Pro app on my Xtrons head unit, but it seems that the AFR is not information that it receives from the ECU. However, the O2 sensor voltages are available so I was wondering if anybody knew the O2 voltage to AFR conversion factor.
Thanks in advance.
