When tuning your car, you need to keep an eye on your Air Fuel Ratio to ensure optimal engine safety and performance   I have one of these in each header to monitor both cylinder banks and log in HP Tuners Pro Suite.

The AFR500v2 is here! We listened to our customer requests and provided just the additional features customers asked for. 

Summary of Changes for the v2:

  • Lambda Display Option
  • Wide Range Option
    • 0.411-1.373 Lambda
    • 6-20 Gas AFR
    • 2.66-8.88 Methanol AFR
  • Increased display speed
  • Bosch LSU 4.9 Option
  • Methanol Display Option
  • Faster analog output
  • All harnesses, control units, accessories, etc (except the LSU 4.9) are backwards and forwards compatible
  • Options are selectable at any time via internal jumpers
  • NTK Calibration grade sensor highly recommended for low AFR methanol applications

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.

Technical information 

Standard Range:

  • Gasoline AFR (9:1-16:1) = 9.00 + Vout x 1.400
  • Methanol AFR (4.00-7.10) = 4.00 + Vout x 0.62
  • Lambda (.618-1.098) = 0.618 + Vout x 0.096


Wide Range:

  • Gasoline AFR (6:1-20:1) = 6.00 + Vout x 2.800
  • Methanol AFR (2.66-8.88) = 2.66 + Vout x 1.244
  • Lambda (.411-1.373) = 0.411 + Vout x 0.1923


Voltage Output from 0v at 9:1 AFR to 5v at 16:1 AFR
