WHY/WHEN YOU NEED THE 02 CLOSED LOOP MODEL: The new 2007 Harley engines utilizing oxygen sensors and closed-loop technology possess lean air/fuel mixtures. This leanness can rob power and make the engines run very hot. The Fi2000 O2 digital fuel processor is designed to work with all H-D exhaust systems (stock or aftermarket) equipped with oxygen sensors in place. It accurately adjusts the fuel-injected engine's air/fuel ratio in order for it to run properly. Best of all it works much like a carburetor jet kit with adjustments similar to the air-mixture screw, the needle and clip positions and the main jet.
• The Fi2000R has connectors that snap directly into the bike's fuel injector bodies, making installation even easier than the Fi2000 models
• Operates with three preset adjustment screws called Pots:
Pot 1 and 2: adjust low speed and mid-range settings that should take care of most lean air/fuel mixture problems
Pot 3: is for high range settings and functions much like a main jet on a carburetor (This third tuning option is for use with engines that have high flow air filters, extensive modifications such as big-bore kits, higher compression or other performance increases where more fuel is required in order for the engine to run properly in full-throttle positions.)
• Improves overall rideability and virtually eliminates backfiring on deceleration
• Installs quickly and easily and comes with detailed tuning instructions (There are no computer settings to make nor Internet downloads to configure)
