See PDF2008 model year and older on road motorcycles originally equipped with an oxygen sensor, as listed in Exhibit A of Executive Order. See PDFThe Fi2000R-ARB is an electronic control box designed to increase fuel into the combustion chamber during high load conditions. It uses the existing oxygen sensor(s) to monitor air/fuel mixtures and increases fuel injector pulse when the oxygen sensor readings show lean conditions. The Fi2000R-ARB is installed electrically in series to the oxygen sensor and the fuel injector wiring harness. No wires are cut during installation and factory style connectors are pre-installed on the wiring harness of the Fi2000R-ARB. The Fi2000R-ARB has no user adjustments and is not designed to allow a user to download or modify the programming.
