Description

SLC Free 2 utilizes the Bosch LSU 4.9 Wideband O2 Sensor - a cost efficient Wideband O2 sensor providing 0.01 Lambda accuracy, fast response, and rated life of 100,000 km

Compatible with all fuel types

Lambda Range: 0.68[Lambda] linear to 1.36[Lambda]

0.01 Lambda accuracy without the need for any calibration

O2 Sensor Temperature Monitor

Did you know that the most common cause of inaccuracies and premature O2 sensor failure is attributed to the O2 sensor temperature being improperly controlled? Only 14Point7 branded Wideband O2 Controllers are able to monitor O2 sensor temperature?

Linear output allows easy interfacing with gauges, fuel management systems, and dataloggers

Linear Output: 0[v]@0.68[Lambda] linear to 5[v]@1.36[Lambda], 10[AFR] linear to 20[AFR] equivalent for gasoline

Note : sensor requires 12V fused power supply
