VFI Closed Loop Fuel Injection Kit. S&S Variable Fuel Injection (VFI) modules for 2001–'03 Harley-Davidson® big twins with Delphi® style fuel injection are now available. Comes packaged with a dual oxygen sensor kit so they can be run in closed loop mode for automatic fine-tuning of fuel delivery – that brings older bikes up to 2007 and later technology. The S&S VFI module offers almost unlimited tuning capacity and can handle just about any performance upgrade possible. Once a base map for a particular configuration is installed, the oxygen sensor kit continuously fine-tunes the engine. To save time getting started, the module is pre-loaded with a fuel map for a touring bike with a 95" engine and the CD includes easily changed calibrations for other models. With the oxygen sensor kit included with the module, this map can be used as a starting point for this very popular engine configuration. Maps for several other engine configurations are on the software CD that is included with this VFI closed loop fuel injection kit. Maps are also available for download here.

The S&S VFI modules are easy to install. They directly replace the stock Harley-Davidson fuel injection module, and plug into the stock wiring harness. Minor wiring modifications are required for the oxygen sensor kit and to retain the "tip over" safety feature of the stock system. Also oxygen sensor bungs must be welded into the existing exhaust pipes. Full instructions are included.
