Our Single Wide Band O2 Sensor Kit is designed to work with our DataMaxx Data Logger system and does not have it’s own display. The O2 kit comes with a single wide band oxygen sensor and a O2 controller box that has the capacity to run two O2 sensors, allowing you to upgrade in the future. Complete air/fuel ratio monitoring system connects directly to the DataMaxx data logger. This versatile tuning aid is designed to work with carbureted or fuel injected engines and the sensor is compatible with gasoline or methanol.
