Whats this about using the second input channel to read the O2 sensor voltage?
The S-AFC has two input channels in order to support cars that have two O2 sensors (such as the awesome Nissan Skyline GT-R). Since we only use the primary input for the O2 sensor, the S-AFC ignores the second channel in the monitor screens. However, we can still view the voltage readings at the Sensor Chk screen, although it is awkward, and there is no logging facility for it like for the other primary sensor inputs.
