Hi
Closed loop boost control has not yet been enabled. You should not select it even if PC Link lets you (it lets me). Only open loop boost control should be available.

Any info you can share with me would be tops mate. Also, where abouts are you doing this (i.e what state)? I had hoped to make up my own loom to plug into the existing harness too. Are you using a WRXLink or a LinkPlus?
Cheers
