Ballenger AFR500CAN – Air Fuel Ratio Monitor Kit – Wideband O2 System

About the Ballenger Motorsports AFR500CAN

As one of the most important supporting tools any tuning professional or enthusiast needs to properly tune a vehicle, finding a wideband O2 monitor with superior quality, accuracy, and functionality is crucial. The Ballenger AFR5000CAN Air Fuel Ratio Monitor applies the same calibration quality AFR ratio from its AFR500v2 with the advantage of plug and play digital CAN Bus messaging. Furthermore, the AFR500CAN offers a massive variety of true wideband sensors depending on your budget.

The AFR500CAN reads AFR values from 9.0:1 to 16.0:1 (0.62-1.1λ) for standard range or 6.0:1 to 20.0:1 (0.411-1.373λ) for wide range with a resolution of 0.1. Additionally, the AFR500 utilizes sensitive Nernst style, pump, and reference cell-based sensors that can detect a broad spectrum of oxygen concentrations to accurately interpret AFR in a variety of combustion environments.

The Ballenger Motorsports AFR500CAN offers a linear analog output to be used as an input to engine control systems, gauges, or data acquisition systems, like HP Tuners. The output varies from 9:1 at 0v to 16:1 at 5v for the standard range or 6:1 at 0v to 20:1 at 5v for the wide range.

The base AFR500CAN comes complete with:

• CAN Flying Lead & USB programming harness
• PC Software for full digital programmability
• Large, bright digital display controller (~3.4in x 2.7in x 1.3in)
