Bazzaz Z-Fi Fuel Controller Suzuki GSXR 1000 

An engine's power is dependent on how well the air / fuel mixture is ignited in the cylinder. Air / fuel ratio (AFR) is controlled by the engine control unit (ECU). Bazzaz fuel controllers piggy back onto the Engine Control Unit (ECU), intercepting the signal sent to the fuel injectors and changing it. The precise data for these changes are stored in the Z-Fi Fuel Controller in the form of a fuel map. The Z-Fi comes pre-programmed with an enhanced fuel map for power gains and improved throttle response. With a proper fuel map the rider can expect a smoother and more responsive throttle along with horsepower and torque gains. 

Motorcycles with any modifications (such as exhaust or high-flow filters) must have fuel tuned to accommodate the change in air to the AFR. 


  • Bazzaz Z-Mapper software makes it easy to view and easily adjust fuel maps
  • Load and save fuel maps that are downloaded, manually edited, created on a dyno, or made with the Z-AFM air / fuel self mapper
  • Switch fuel maps on the fly with the handlebar-mounted Bazzaz Z-Fi Fuel Map Switch
  • Made in USA
