WB-O2 Nano is characterized by an extended reading scale up to 0.35 λ*, compact size and CAN communication with our Power FT line ECU controllers. This is very useful when using O2 sensors per cylinder. The reading from the O2 sensor is sent via CAN to the ECU and recorded in the internal datalogger, without using any analog input. *The reading scale can be larger or smaller than 0.35 λ, in depending on the characteristics of the sensor.
