over and under rev protection
The system monitors the engine speed and will automatically
shut the engine off if the RPMs rise above or fall below the
programmed levels. This feature prevents damage to the motor
due to fuel delivery system failures or other problems which may
cause the engine to race.
shut down inputs
This system uses several inputs to shut down the remote start
operation of the motor or prevent remote start if certain inputs are
active. These are the hood and brake inputs. The hood input will
prevent the motor from starting, as well as shut it down, any time
