this device is intended to help you "tune" your bike. You can't tune a bike blindly without knowing what afr is on a dyno or logger. I am trying to help you from hurting something. you can de-restrict 6th gear, increase limiter, hard cut / soft cut etc, ignition shift kill, plenty of things that can be done, but the main focus is to tune fueling and ignition, which just can't be done by guessing.
