Control your air/fuel ratio from fuel injectors to improve horsepower, torque, and throttle response. Correct fuel delivery for maximum performance, especially after modifications such as an aftermarket exhaust. The Bazzaz Z-Fi Fuel Control Unit takes operational command of all fuel injectors, not just half like competitors. This is a significant advantage in realizing the perfect tune, resulting in significantly better throttle response and overall engine performance. Z-Fi is a plug and play unit that piggy-backs onto the stock ECU. Each unit comes with an application specific harness that utilizes OEM connectors for simple installation. Stores two modifiable fuel maps, one pre-programmed for specific bike with a slip-on exhaust.
