Fuel Tuning

The most efficient way to true performance.


'Wakes up' performance

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 ECU, intercepting the signals sent to the fuel injectors and modifying them.
The precise data for these changes is stored in the fuel controller in the form of a fuel map.

Who needs it?

Every vehicle can benefit from fuel tuning.
Stock vehicles may come with an air/fuel mixture that can be too lean or too rich in various areas, affecting performance.
Vehicles with any modifications (such as exhaust or high-flow filters) must have their fueling tuned to accommodate the change in air volume to the AFR.
Variables in fuel tuning include: fuel blend or type, engine wear, exhaust, filter, engine modifications, air temperature, air pressure, and humidity.


Our fuel controllers and self mapping module make advanced fuel tuning simple.

The Z-Fi fuel controller is what stores the fuel maps. Plug and play to get started. Tune to a higher level with easy to use software.
