Changes by last author:

Changed:
* The Goal: The goal here is to have a simple microswitch trip when the front wheel comes off the ground. The switch will connect with the VEMS unit to initiate a reduction in boost to reduce power and stop the wheelie without having to reduce throttle.

Changed:
* Track time would have to determine how much to reduce the boost. In the case of my bike as the wheelbase has been extended 8", it wouldn't need to be much. In fact, wheel spin is likely to be as serious a threat to performance.

* In fact, with 300 hp wheel spin is likely to be as serious a threat to performance.

* A manual override could be put on handlebars inline to induce boost reduction all the time (for safety on rainy days, etc.) more like a typical 2 stage boost control setup.

Because of latency of the system (retard works fast, but boost needs some time to decay) it might worth investigating a system that provides an early warning signal. maybe

* more than 1 switches in different positions

* analog inflation indicator

* or an inductive coupling system (similar used for pedal position sensors and other drive/fly by wire equipments). Very appealing but requires some (simple) electronics.
