The New WB-O2 Nano keeps your O2 sensor at the optimal temperature for accurate readings with 3 configurable heating modes via CAN; normal, fast, and current limited, in addition to auto startup. Additionally, it has an extended wideband reading scale with advanced hardware for fast and precise readings (reading range can reach values slightly lower than 0.21 λ).

Datalogs via CAN communication with our PowerFT and VisionFT line of ECUs, and allows multiple conditioners for bank to bank or individual cylinder O2s, all through the CAN network, preserving your ECU’s analog inputs for other sensors.

The display is a familiar look from our original nano, with some new options including day/night dimming configurability, shift light alert, and now is paired with an updated case to match the NanoPRO mounting points.

The New WB-O2 Nano is IP67 rated (when properly connected to the harness), making it perfect for marine, off-road, and automotive applications.
