I think they are showing how idle timing compensates idle speed for loads at idle. Like being in drive, or maybe the A/C compressor kicking in,. By bumping the timing a bit, then can bring the idle speed back up. Thinking thats the reason the idle RPM's are entered in the app. Kind of a cool idea. I would think you still set the idle and base timing the same way you would otherswise.? this is just my guess of course after watching the video.
Would allow for a lower baseline idle similar to a manual shift car. Pretty much what is mentioned above
I would imagine that feature has an RPM cutoff to work correctly? hits 1000 or more and assumes your stepping on the throttle?
