About the New Ballenger Motorsports AFR500v3 Air Fuel Kit

As one of the most critical tools a tuner requires for properly calibrating a vehicle, the AFR500 Air Fuel Ratio Monitor provides professional grade measurement of air-fuel-ratio without breaking the bank. This kit offers a linear analog output to be used as an input to engine control systems, gauges, or data acquisition systems and is compatible with HP Tuners’ software for diagnostics and calibration.

This AFR500v3 kit is capable of reading air-fuel ratio values from 9.0:1 to 16.0:1 (0.62-1.1λ) (standard range) with a resolution of 0.1 to provide excellent resolution in the tuning range of most performance vehicles.

Summary of Changes for the AFR500v3 and AFR500v3CAN:

  • A digitally derived output with a higher resolution digital/analog converter.
  • 4X times the measurement resolution (4096 increments compared to the previous 1024).
  • The ASIC chips, one of the most common points of failure from electrostatic damage, have been replaced with a custom board providing better protection and upgrade capabilities.
  • The ability to display from 0.0 to 6.0 in lambda setting for better flexibility with alternate fuels such as diesel.
  • Ability to upgrade firmware for future sensor types.
  • All harnesses, control units, accessories, etc. are backward and forward-compatible.
  • Options are selectable at any time via internal jumpers.
  • NTK Calibration grade sensor highly recommended for low AFR methanol applications. NTK Production Grade is the least expensive sensor we recommend for methanol applications.

The base AFR500v3 includes the following:

  • Large, bright digital display controller (~3.4in x 2.7in x 1.3in).
  • 13ft wiring harness with sealed connections.
  • NTK Production Grade Sensor.
  • Standard measurement range.
  • Display gasoline (standard).
  • Weld in steel exhaust boss and plug.
  • Mounting Velcro.
  • Comprehensive Installation, troubleshooting, and tuning manual.
  • 0-5 volt Analog Output Signal.
  • 11-28 volt Input Power (24v system capable).
  • Compatibility with most aftermarket ECUs.
  • Compatibility with HP Tuners.
