TUNE FOR HIDDEN POWER & DURABLILTY

FAST™ Wide-Band Air/Fuel Gauge Kits
Single/Dual Sensor and now 2 1/16” gauge style Wide-Band Air/Fuel Kit

Stop guessing and start tuning for additional horsepower! This is the first tool you need when tuning engines for maximum horsepower & torque.

Proper engine tuning is vital to achieving maximum performance and avoiding costly component failures. Until now digital air/fuel meters have only offered single sensor measuring capability. This meant engine tuners were only able to monitor the air/fuel ratio in one side of the engine, while being left to play a guessing game with the other engine bank. Now there is a way to eliminate the unknown, allowing you to tune with confidence and complete accuracy.

FAST™ has developed an easy to use Dual or Single Sensor Air/Fuel Meter that delivers the complete story about your engine’s tuning. you will now haave the same technology that tuners have, and the power to read two wide-band O2 sensors individually or average them together for super accurate readings of the engine’s true air/fuel ratio.

Beyond the innovative dual sensor capability, the FAST™ Dual Sensor Air/Fuel Meter delivers all the features that tuners have come to expect, plus several enhanced capabilities, in the easiest to use format of any digital air/fuel meter ever developed. One such feature is built-in data logging capability that plays back recorded information on a lighted, full graphical display screen, unlike other units that require downloading to a computer. Additional standard features include outputs for external data loggers, digital gauges, as well as a narrow-band simulator function that allows you to feed your engine’s computer a factory signal while using the wide-band sensor for air/fuel measurement.

/SNIPER TUNING Wide-Band Air/Fuel Meter/

Regardless of what some people may claim, it is impossible to properly tune a fuel injection system on a modified engine without some means of exhaust gas analysis. Sniper offers the AF-5000 as a low cost alternative to expensive systems. Conventional (narrow-band) exhaust gas oxygen sensors have been widely used in automotive applications since 1981. Conventional sensors have one to four wires and can only sense air/fuel ratio over a relatively narrow 14.5 to 15.0 range. They are intended to be used with 3-way catalytic converters that require operation near the stoichiometric point (14.7 air/fuel ratio). The range of narrow-band sensors is inadequate for performance tuning. While originally developed for lab and specialized automotive applications, wide-band sensors are ideal for tuning. The 5-wire Bosch LSU 4.2 sensor used with the AF-5000 operates over a range of 10.3 to infinite air/fuel ratio.

The AF-5000 features built-in data logging. This data logging capability greatly facilitates engine tuning and diagnosis of driveability issues. The AF-5000 can store data up to 2 hours of operation. You can use our WEGO Log software to download and display this data on a chart recorder type screen.
    Available data includes:
  • AFR (air/fuel ratio)
  • RPM
  • 0-5V analog.
Additional Sniper AFR features include:
  • Complete air/fuel ratio metering system with built-in data logging. Includes WEGO II Wide-Band Exhaust Gas Oxygen Sensor Interface, Bosch LSU4.2 5-wire wide-band oxygen sensor, 18x1.5mm weld nut for mounting sensor on exhaust pipe, and software on CDROM
  • Versatile tuning aid for all carbureted and fuel injected engines displays AFR (air/fuel ratio) and logs over 2 hours data including AFR, engine RPM, and a spare 0-5V analog input for sensors such as throttle position or manifold pressure.
  • Can be used for on-road or dyno testing.
  • Suitable for automotive, motorcycle, and other small engine applications.
  • Highly accurate with less than ±0.10 AFR error over 10.3 - 19.5 AFR range.
  • Easy free-air calibration procedure corrects for sensor aging effects.
  • Red LCD display with backlight provides great readability in all conditions ranging from bright sunlight to total darkness.
  • Compact size: 3.7"L x 1.7"W x 0.75"H.
