- Three easily identifiable lights: green - Fi2000R is adding more fuel to the air/ fuel ratio approx. 14:1; green and yellow lights - these lights will be on in unison when throttle is open more quickly and air/ fuel mixture is approx. 12.5:1; red - light comes on and stays on as long as the Fi2000R follows the fuel curve while adjusting to approx. 12.8:1 air/fuel ratio, which is where the engine will produce its best full-throttle power
- Corrects lean air/fuel mixture problems; eliminates overheating, hesitation on acceleration or an uneven cruising RPM
- Pre-configured from the factory for your make and model, but easy to adjust should your specific application need it
- Improves rideability by smoothing out the powerband and giving the bike more throttle response
- Full range of fuel adjustment (0-10 settings) across all RPM ranges
- No fuel map adjustments or computer downloads required
- More advanced tuning for modified bikes
- Plug-in OEM style connectors
- Step-by-step instructions
