Wideband kit fits most Polaris models and works with your PV3 module. This is the module we use in development of tunes to easily log/view air/fuel ratios. This is helpful for those with custom setups, or if you simply want to keep an eye on your air/fuel ratio ensuring your fuel system is in good working order. If you have a wideband RZR turbo model with the blue o2 sensor lead, this would not be necessary as you can log real time AFR's already on the PV3 The Wideband module plugs into the vehicle’s diagnostic port and seamlessly integrates AFR data from the included wideband O2 sensor(s) with the OEM databus. When used in conjunction with Power Vision you can view and data log wideband O2 data alongside custom channels directly from the vehicles diagnostic port. The logs are stored in the Power Vision memory and can easily be downloaded for review in DynoJet’s Power Core Software Suite. The Wideband CX is a plug-and-play kit with no extra cables for power, ground, and signal that are typically associated with wideband controllers. Wideband CX ensures real-time wideband O2 AFR accuracy with negligible latency and avoids any signal offset issues with its industry first, innovative design.
