- Three easily identifiable lights: green - Fi2000 is adding more fuel, making the air/fuel ratio approximately 14:1; green and yellow lights - these lights will be on in unison when throttle is open more quickly and air/fuel mixture is approximately 12.5:1; red - light comes on and stays on as long as the Fi2000R follows the fuel curve while adjusting to approximately 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, backfiring on deceleration, hesitation on acceleration or an uneven rpm
- Can fine-tune the non-acceleration air/fuel curves using the Bluetooth® app
- Works with stock or modified engines, air cleaners, and exhaust systems
- Uses T-tap connectors
- Made in the USA
