VARIABLE FUEL INJECTION MODULES (VFI) FEATURES AND BENEFITS • Directly replaces stock Harley-Davidson® fuel injection modules – plugs directly into stock wiring harness • Includes ProTune II software and can be updated at sscycle.com/tech-info/ software/protune-ii • Three stage engine overheat protection helps prevent possible engine damage caused by improper modifications to fuel maps

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 The Barometric Sensor Relocation kit (part #55-1599) is required for any complete S&S T-series engine installed in a 1995–2001 EFI touring chassis or any engine used in these applications using the S&S T-series oil pump where the stock cam position sensor cannot be used. All current production S&S modules are closed loop compatible, and all older S&S modules can be updated with current calibration by simply download- ing software from the S&S website at sscycle.com/tech-info/software/ protune-ii Please note that maps created for older versions of the VFI software are not compatible with the new closed loop software, however they can be converted to closed loop if desired. S&S VFI systems installed on 2004–up Harley-Davidson® models incorporate a speedometer calibration feature.

• Altitude compensation automatically adjusts for altitude variations • Live tuning allows manual changes to maps while the engine is running • Self diagnostics and actuator test functions help tuning and verify proper installation/operation • Engine light can be programmed to function as a shift light • Closed loop capable • Knock sensing ignition control (USB Delphi® style unit only) • Optional closed loop sensor kit extend module capabilities • Speedometer calibration function for 2004-up Harley-Davidson® models ( does not require installation of separate speedometer calibrator)
