I might not be understanding how the input mappings work. For example, I created a canbus xml custom input imported value, and in the input mapping, I set the imported value to be set by a dummy timer, but nothing happens on the imported value. Am I doing something wrong?

In input mapping you select two values, source and destination. When ever source value changes, it is set into destination.

Dummy timers are force updated by the system so you probably just get a ‘flash’ from mapped value until timer is updated again internally by RealDash.
