FAST™, the recognized leader in EFI technology, has developed an easy-to-use Dual Sensor Air/Fuel Meter that delivers the complete story about your engine’s tuning. Tuners now have 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 new 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 unit’s 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 wideband sensor for air/fuel measurement.
