New digital input: Tachometer, show monitor value x to trigger the value presentation, Tach output.

New digital input: Neutral switch input and neutral switch interlock to the Starter motor control.

Starter motor input will now turn off the engine if it's pressed while running.

The minimum speed limit value changed to 5km/h (10km/h before) in Speed limiters.

New Tachometer value presentation function for the Tach output, to show any RealTime Data value on the tachometer for a short time (boost setting, tune selector position etc).

Added a sweep function to the Speedometer output.

Added a new tripmeter with a Tripmeter, reset input in distance counters.

Added settings to Idle control settings, to control the PID range either in absolute position (as before) or relative to the open loop position.
