On-Screen Timing Advance
The on-screen display of the current actual timing advance is primarily used for diagnostic purposes, for example a timing miss-match or a disconnected manifold pressure source. Other than that, its just one more thing to watch so you don't have to look out the window.
Kidding aside, the real value is the means to set the timing advance exactly for your engine and your desired performance objectives. All the things you can do with your EI Commander.
