The WBC purpose is to “operate” a BOSCH LSU4 wide band lambda sensor for the accurate measurement of AFR values from 10 to 20 AFR.

• Small size
• Temperature controlled heater circuit
• Indication of heater and sensor malfunction
• External fault reporting
• Linear 0-5 Volt output reporting AFR
• High-resolution lambda conversion
• Bar graph AFR indication
• Low power consumption
