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.
