F.A.S.T. Air/Fuel Meter - Single Sensor

Ideal for carbureted and EFI engines, this Air/Fuel meter kit features a standard length harness for use with cars. Requiring no laptop, this single sensor kit can datalog internally which is ideal for tuning on the go.

With no laptop required, FAST has developed three simple, easy-to-use air/fuel meters for gasoline, diesel and Ethanol/Methanol (E85) fuels. Available in single or dual sensor units, these meters give tuners the power to read two wide-band O2 sensors individually or average them together for maximum accuracy of the engine's air/fuel ratio reading. The FAST Air/ Fuel Meters include several enhanced capabilities, including the built-in data logging capability that plays back recorded information on a lighted, full graphical display screen rather than using a laptop computer. Additional 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.
