I really hope you have some sort of plan to customize your engine management after doing this install. Otherwise......BOOM.
ok lets say he does, i kind of want to know how to anyways. i will be doing the same thing in a while. be cool to no how.
Ummmm....run new vacuum lines to the turbo, wg actuator and to the turbo inlet. Hook up the power from the harness, adjust the wgdc table in the ecu and then enjoy quicker spool. That's about it in a nutshell.
i have a vishnu stage 1 and my stock ebcs went out so the guys at the minnetonka morries suggested that i get this one since its a little cheaper and better...
i found this pretty good picture though http://i46.photobucket.com/albums/f137/SpDRcrWrex/WRX/my wrx/tech pics/ProdriveBCS_3port_hookup.jpg
Yeah....or try to find a used one. There's quite a few guys running aftermarket 3-port BCS controllers, so there's a good chance of finding a used stocker.
