Ballenger AFR500v2 with NTK Sensor

The Ballenger Motorsports AFR500 Air Fuel Ratio Monitor has proven very successful. In a world where cost-cutting reigns supreme, we’ve kept the calibration quality air fuel ratio meter made by ECM going strong. Previously sold as the NGK Powerdex AFX, it was replaced in the NGK/NTK product line due to high cost and low margins despite its popularity. Sometimes quality comes at a price, and we plan to keep offering this high quality product to consumers, dedicated tuners, and industry professionals.

The AFR500 makes true wideband technology with top of the line measurement equipment available to enthusiasts and tuners for the first time. Air fuel ratio offers critical feedback for tuners to alter parameters to achieve maximum power and efficiency from their engine.

The Ballenger Motorsports AFR500 Air Fuel Ratio Monitor offers a range of true wideband sensors from low cost options to lab grade sensors. No competing system offers this flexibility in this price range. Comparative systems typically sell for thousands of dollars for dedicated calibration equipment. The AFR500 is capable of reading air fuel ratio 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 to provide excellent resolution in the tuning range of most performance vehicles. The Ballenger Motorsports AFR500 utilizes sensitive Nernst style, pump & reference cell based sensors that can detect a wide range of oxygen concentrations in order to properly interpret air fuel ratio in a variety of combustion environments.

The Ballenger Motorsports AFR500 offers a linear analog output to be used as an input to engine control systems, gauges, or data acquisition systems. 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.

Summary of Changes for the v2:
