What goes into a Livernois Motorsports Custom tune?


 Fuel Mapping- The fuel map inside the ECU is able to adjust the air/fuel mix for maximum efficiency and performance in any condition.

 Air/Fuel Management- Air/Fuel management is one of the most important factors in the combustion process. Maintaining a proper Air to Fuel ratio is crucial to getting the most out of your motor and also to prevent damage.

 Rev, Top Speed Limiters and Shifting Characteristics- By dialing in the optimal RPM range and pressures for your transmission to shift at we are extending the life of those components. We also take this opportunity to revise your top speed limiter. These modifications are made to make sure that you are able to have a long-lasting and fun life with your vehicle.

  Timing- Timing is where we control when the combustion event occurs. By revising the moment this happens we are able to increase your vehicle’s performance and efficiency!

 Torque Management- Using our proprietary tuning software we alter when, where and how the computer tries to step in maintain control over your vehicle in a performance setting.

 Tire Size Alterations (Where Available)

 Axle Ratio Alterations (Where Available)
