Stop guessing and start tuning for more horsepower!

KEEP TRACK OF GASOLINE/ALCOHOL AIR/FUEL RATIOS WITH FAST™
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 on one side of the engine, while being left to play a guessing game with the other cylinder bank. Now there is a way to eliminate the unknown, allowing you to tune carburetor jetting and EFI air/fuel ratios with confidence and complete accuracy.

MONITOR A/F RATIOS WITH EITHER 1 OR 2 SENSORS
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. And with its built-in methanol capability, racers who run “wood alcohol” can tune more accurately than ever before!

MORE FEATURES THAN COMPETING METERS
Beyond the innovative dual sensor capability, the new FAST™ Dual Sensor Air/Fuel Meter delivers several enhanced capabilities, in the easiest to use format of any digital air/fuel meter ever developed. One such capability is built-in data logging capability that plays back logged information on the lighted, full graphical display screen, unlike other units that require downloading to a computer. Additional standard features include outputs for external data loggers and digital gauges, and a narrow-band simulator function that allows you to feed your engine’s computer a factory signal while using the performance-oriented wide-band sensor for air/fuel measurement and adjustments.
