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.
Aggressive camshaft profiles, high compression, and most other horsepower-increasing modifications seldom run well with even the most radically tuned factory ECU. And if the project at hand is swapping a late model EFI engine into an older vehicle, prospective new “fuelie” guys have to gain a whole lot of electrical knowledge in a hurry, or dig that tired carbureted setup out of the pile of obsolete parts in the back of the garage. That’s where FAST™ steps in to save the day with XFI™ -the easiest to install and tune aftermarket EFI system in the industry!
