Proper engine tuning is essential to achieving maximum performance and avoiding costly, premature engine failure. Unfortunately, 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 carburetor jetting and EFI profiles with confidence and complete accuracy.
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 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.
Stop guessing and start tuning for additional horsepower and reliability with the new FAST™ Dual Sensor Air/Fuel Meter.
