AuthentiKit Tuning App 1.4.0

Takes button/encoder inputs and turns them into a virtual axis that you can tune for optimal experience in sim (e.g. map the number of turns of a trim wheel more precisely), and much more!

What does it do?

This software maps joystick buttons and encoders to virtual outputs that can be tuned for an optimal in-sim experience. Outputs can be virtual axes, or virtual buttons. A typical use would be mapping your AuthentiKit Spitfire elevator trim wheel to a single virtual axis that you use in sim. What's more, you can tune the sensitivity of the axis to approximate the correct turn rate of the trim wheel in sim. There are various other mapping types to choose from too, as specificied in the user guide.

The software is primarily for the our community, so if you have an AuthentiKit project that you think think the software could help with, do reach out!
