Install of the Gizzmo MS-iBC is pretty damn easy. You have the solenoid that I put out by the turbo with 2 wires. Then you have power. Hook up the boost reference and that's it. There's 2 more wires if you want an external scramble/setting button. The menu and navigation is a little odd so I keep the manual handy. It's 6 settings, all independantly adjustable, all have closed loop options. Set the gain and duty, do a pull to dial in the response/level, turn on closed loop and you're done. Button can be used to select the next boost setting [1-6] or trigger a scramble which will up the boost (to a level you program) temporarily. Like if you're on a track and want to get around someone... hit the button to dial up more boost to get around him. It doesn't try to be everything to everyone. It just does what it's supposed to very well. I like that it's compact and the display is just numbers.
