Hard Limiter

The hard limiter helps prevent engine damage due to overheating by attempting to limit engine speed when it exceeds the value defined in currently-selected version of the Hard Limiter Engine Speed Threshold map.

NOTE: There are 4 versions of this table so multiple configurations can be stored. Use Hard Limiter Map Select to specify which of the 4 tables to employ.

This is the final line of defense should the soft limiter or staged cuts prove insufficient.

The method used to limit engine speed is selected using Hard Limiter Cut Mode.

When the engine speed falls below the Hard Limiter Engine Speed Threshold from the selected map minus the Hard Limiter Engine Speed Threshold Hysteresis from the selected map, the hard limiter will wait for the additional amount of time specified in Hard Limiter Timed Hysteresis. Then, it will stop trying to limit engine speed.
