Id suggest that you get a users manual from somewhere.
If you cant find your problem,then you should assume that its your solenoid.
Here you go i may be able to help you.heres a link to a blokes site where he has installed a profec a on his rotary.The diagram shows the points at which the boost controller should be connected.And it is for an internaly actuated wastegate like the one youve got.
