Air-Fuel Meters & Loggers

AFA-4 Multi Channel Wideband System

Professional grade wideband system used by top NASCAR engine builders

  • Ideal for all racing engines running ANY fuel included leaded gas
  • Measures actual air-fuel ratio or lambda. Displays air-fuel ratio for gasoline or methanol.
  • Uses the Bosch LSM-11 sensor which is very lead tolerant.
  • Easy interface to any data logging system. Has optically isolated 0 – 5 volt analog outputs which eliminate ground loop and ground elevation errors.
  • 4 Channel controller greatly simplifies installation.
  • Accuracy is better than +/- 0.1 AFR over the full range. Repeatability is better than .05%. Response time .02 seconds.
  • Has 0 – 5 volt linear outputs (for both channels) which are compatible with virtually any data logging system.

WBAF-4D Dual Channel Wideband With Display and Data Logging

Great entry level data logger for engine tuning. Tuning with air-fuel ratio logging eliminates guesswork!

WBAF-4D Data Logging Features

  • Logs 2 channels of Air-Fuel Ratio, RPM, and one analog sensor (0 – 5 volt) such as Throttle, Fuel Pressure, or Manifold Pressure.
  • Automatic start and stop of logging, USB download to PC.
  • Always saves the most recent data in flash memory.
  • Logs 40 minutes @ 5 samples per second, Sample rate selectable from 1 to 10 samples per second. Simple, easy to use software included.

The WBAF-4D, ideal for V6 & V8 motors and Twin Cylinder bikes, is a 2 channel wide band air-fuel controller that includes a display and data logging features. Suitable for in-car or on-dyno use. It is compatible with Methanol, Ethanol, Leaded and Unleaded Gasoline. (Sensor life is limited when used with leaded gasoline.) Our experience is the sensor lasts from 10 to 50 hours of run time on leaded gas, life depends on lead content and number of heat cycles.

 

  • Measures actual air-fuel ratio or lambda. Displays air-fuel ratio for gasoline or methanol.
  • Ultra bright daylight readable blue LED display with automatic dimming in low light conditions.
  • Easy free-air calibration proceedure. Uses the Bosch LSU 4.2 sensor which is accurate and low cost.
  • Unlike many other wide bands, the WBAF-4D output does not vary when power supply voltage changes. This is extremely important in cars running total loss ignition. Voltage output is constant with power supply voltage of 11 to 16 volts.
  • Accuracy is better than +/- 0.1 AFR over the full range.
  • Has 0 – 5 volt linear outputs (for both channels) which are compatible with virtually any data logging system.
  • Compact size: 4.2″ x 3.1″ x 1.1″
  • If your current data system is maxed out or if you do not have a system this is the least expensive way to get in to logging Air-Fuel Ratio!

WBAF-3 Wideband With Display and Data Logging

Great entry level data logger for engine tuning. Tuning with air-fuel ratio logging eliminates guesswork!

WBAF-3 Data Logging Features

  • Logs Air-Fuel Ratio, RPM, and one analog sensor (0 – 5 volt) such as Throttle, Fuel Pressure, or Manifold Pressure.
  • Automatic start and stop of logging, USB download to PC.
  • Always saves the most recent data in flash memory.
  • Logs 26 minutes @ 5 samples per second, Sample rate selectable from 1 to 10 samples per second. Simple, easy to use software included.

 

The WBAF-3 is a wide band air-fuel controller that includes a display and data logging features. Suitable for in-car or on-dyno use. This miniature controller is fully encapsulated, completely waterproof and can be mounted in any engine compartment. It is compatible with Methanol, Ethanol, Leaded and Unleaded Gasoline. (Sensor life is limited when used with leaded gasoline.) Our experience is the sensor lasts from 10 to 50 hours of run time on leaded gas, life depends on lead content and number of heat cycles.
