MSD offers replacement wiring harnesses for the Power Grid Dual NTK wideband oxygen module—a dual channel air/fuel ratio (AFR) system designed to interface with the Power Grid (P/N 7730) to monitor and record the AFR of internal combustion engines. The oxygen sensor module is capable of measuring AFR as low as ? = 0.5 (7.35:1 gasoline AFR equivalent). The AFR range is configurable using the MSDView software in conjunction with the Power Grid Controller (P/N 7730). Excellent MSD range of the NTK sensor gives each unit the ability to accurately monitor AFR's even on alcohol cars. The MSD wideband oxygen 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. (To provide accurate backpressure compensated AFR readings on turbocharged applications, the addition of an Exhaust Pressure Module, part number 7767, is required.) MSD can provide a replacement main harness, sensor 1 harness, or sensor 2 harness for your application. Order the model needed to restore proper performance to your vehicle.
