Hello.
maybe what you need is already there.
edit the SimDash.exe.config file that is in the SimDashinstallation folder.
change these lines:
<setting name="ShowTestControls" serializeAs="String">
<value>False</value>
</setting>
to:
<setting name="ShowTestControls" serializeAs="String">
<value>True</value>
</setting>
Now start SimDash. In the Pro-Shift configuration screen there is a new DEMO button.
if you click it, all the LEDs are switched on in sequence, from LED 1 to LED 16, one at the time.
Is it what you needed?
Regards
