i'm using EVC 5 (japan) or EVC 6 (usa) same thing but different version in this 2 country. found it very useful, i can have 4 setting of boost. when off it run on the actuator capability and when on you get to have 2 profile of setting and a scramble mode which you can set amount of add on boost to profile a or b and set a timer to run on that.
good for money
