A dual channel air-fuel ratio (AFR) system designed to interface with the Power Grid (PN 7730) to monitor and record the AFR of internal combustion engines.

Part Number: 7766

To provide accurate backpressure compensated AFR readings on turbocharged applications, the addition of an Exhaust Pressure Module, part number 7767, is required. The MSD Wide-Band O2 Sensor module also provides a 0.5-4.5 VDC analog output proportional to the AFR. This analog output can be sent to a gauge or a data acquisition system. A dual-color LED provides the system status at a glance. The MSD Power Grid Dual NTK Wide Band O2 Module is a dual channel air-fuel ratio (AFR) system designed to interface with the Power Grid (PN 7730) to monitor and record the AFR of internal combustion engines. The Dual Wide-Band O2 sensor module is capable of measuring AFR as low as λ = 0.5 (7.35:1 Gasoline AFR equivalent). The AFR range is configurable using the MSDView software in conjunction with the Power Grid Controller (PN 7730). Excellent range of the NTK sensor gives this unit the ability to accurately monitor AFR's even on alcohol cars.
