So I see people moving the numbers around and can feel how the different maps work better here and worse there but what do the numbers mean?
For ignition, is going negative the same as advancing or retarding the ignition?
For fuel injection, are the numbers increasing fuel or changing the timing of the fuel injection?
Also, is it possible to create a curve that will overfuel or damage the engine?
Thanks!

On the old, hand-held devices, you could advance or retard the timing and increase (richen) or reduce (lean) the fuel flow in several RPM ranges and throttle settings. Based on what I saw of the video above, it looks much the same with the app.
EDIT: On the old handheld device, it was possible to make your bike run poorly, but not enough to damage it. I would be very, very surprised if Yamaha made something that allowed you to wreck your bike.
I pick up my bike soon and I'm looking forward to getting a feel for the changes it can make to the feel of the bike; like does ignition adjustments have more of an impact than fuel or vise-versa.
My understanding is that while you can tune dramatically, you can't break the bike with the tuner.

BTW, so far the best map that came with the tuner is the Hard Hitting(Loamy). To feel the difference, I suggest leaving the factory tune in Map1 and upload Hard Hitting(Loamy) into Map2. Then, hit the button after riding a few laps, you'll feel it!
Thanks!
