The ECU controls the inlet manifold pressure by applying an ignition cut and/or a fuel cut. The MAP limit mode also has a second switchable limit table that can be used for a different scenario
      • Speed limit mode that limits the vehicle speed. The maximum allowed vehicle speed is configured by the tuner and is able to be switched on or off. Perfect for use as a pit lane or valet speed control. The tuner can choose to use a driven or non-driven wheel speed source. The ECU controls the vehicle speed by applying an ignition cut and/or a fuel cut
      • Two general purpose RPM Limit modes, these 3D tables have configurable axis and so can be used for many different purposes. One typical use is to control the maximum engine speed based upon oil pressure. If the oil pressure drops the table can be configured to limit the engine speed or completely shut the engine down. The ECU controls the engine speed by applying an ignition cut and/or a fuel cut
      • Each of the above limit modes has the option of using the default limit settings, or the tuner can open the advanced limit settings and have absolute control over how the limit system functions
      • Each limit mode has an adjustable limit control range over which the limit is progressively introduced. This allows very smooth limiting to be achieved and is not harsh on the engine
      • Each limit mode also has the option of applying a hard limit in case the soft limit is not adequate
      • Other limit settings configurable by the tuner include an ignition retard trim, an engine start-up lockout and an activation delay
      • Each ECU also has a system voltage limit mode that is used to help protect the vehicles electrical system if the charging system voltage rises above the value set by the tuner. In the event of the system voltage exceeding the level set the ECU will shut down the engine
