There are lots of differant types of Electronic boost controllers, I have the Blitz SBC ID-3
it's basically a solonoid which changes the point the actuator opens the wastegate, basically like a manual boost controller with an electronic control unit in the cockpit, comes with install instructions and are pretty easy to install
on the Blitz one i have Setting it is pretty easy, you have the option of 4 differant boost settings and also a boost map function ( basically mapping the boost acording to speed) if you have the Power Meter, it also has other functions like outside imputs ( with an optional Harness ), I have mine set up to out put the factor ECU readings for the Intake temp and Water Temp, It also has a digital boost guage built in, You can set it from anything between 0 to 3bar,
there are other options available but i would recomentd either the Blitz, HKS or Apexi Units because of quality and funcionality
