We took the industry’s best electronic fuel management system and improved it for 2004 with additional tuning options and a sleek new design. The new Fi2000 retains the simple installation and easy adjustments that made it so popular, but now features a third tuning pot for use with modified engines. Think of the third pot as an electronic main jet. Now the Fi2000 offers a full-range of fuel adjustment across all rpm ranges. The Fi2000 can handle your tuning needs even if you opt to upgrade your air intake or perform more extensive engine modifications.
