Example - Custom Electronic Ignition Advance Gauge – The following two screenshots are an example of
an installer-defined engine gauge used to display the timing advance for an electronic ignition which
outputs 0.01 V/deg. In this example the gauge spans from 0 to 45 degrees of timing advance with tick
marks at 20 degrees and 40 degrees.
Vertical Power: When using a Vertical Power unit, trim and flap positions will automatically be displayed.
Connecting, configuring, and calibrating the POS inputs is not required when the position sensors are
connected to a Vertical Power unit.
