  • This wideband O2 gauge is an extremely accurate and capable unit. Complete with its own LCD display, it makes precision fuel injection tuning easy.It allows the user to monitor and record O2, throttle position, RPM, and one other 0 to 5 volt analog input such as manifold air pressure, boost pressure,etc. It can be used as a stand alone unit or connected to a Power Commander V (PCV). When connected to a PCV, the injector duty cycle and percent of change can also be monitored and recorded. It has the ability to test the sensor condition at any elevation to insure the data you are receiving is accurate. The LCD display is a touch screen making it simple to use. A 1 GB SD Card is required for storage to use the record feature (1 GB is the maximum useable size). This unit is extremely beneficial for precision fuel injection tuning.
