Wideband O2 sensor display and conditioner for Bosch LSU 4.2 sensors.
 
The WB-O2 Nano features an extended reading scale down to 0.35 λ*, compact sizeand CAN communication with our Power FT line ECUs. This is very useful when using O2 sensor per cylinder. 

The O2 sensor reading is sent to via CAN to the ECU and recorded in the internal datalogger, without using any analog input.
