Bazzaz Z Fi

The Z-Fi fuel controller is race-level fuel injector tuning.


  • ‘Wakes up’ performance
  • Crisp and responsive throttle
  • Smooths out throttle transitions
  • HP and torque gains

How it Works:

  • 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 is 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.

Who needs it?

  • Every vehicle can benefit from fuel tuning.
  • Stock vehicles may come with a fuel / air mixture that is too lean or too rich in areas, affecting performance.
  • Vehicles with any modifications (such as exhaust or high-flow filters) must have fuel tuned to accommodate the change in air to the AFR.

Take it to the next level.
