Im wondering if there is a switch that is activated by boost or rpms. i want to have the alcohol injection turn on at certain boost or at least rpms, instead of manuel, but can't find anything of such sorts.

They make a great kit. One question though, why? On a 9:1 motor you can run 18+ pounds of boost on pump gas and make way more power than is controllable in a street car.
