Closed Loop Capability • When equipped with a dual closed loop sensor kit and running in closed loop mode, VFI tuning becomes a breeze! S&S supplies base maps for several displacement groups, creating a starting point to get bikes up and running Utilizing dual oxygen sensors (sold separately) placed in the exhaust, the S&S closed loop system modifies the base fuel map to meet the specific requirements of your engine! • Automatic tuning on the street or on the dyno • Each cylinder is tuned individually • Fuel map changes are saved in the module and can be merged with the pre-loaded base map • Works with stock oxygen sensors used on late model Harley-Davidson® motorcycles Closed loop VFI can also automatically compensate fuel delivery for modifications creating up to a 20 hp gain, such as changes in: • Displacement • Cams • Exhaust • Head porting or installation of aftermarket heads
