Does anyone have a link to some good docs on how the impreza turbo is controlled -

I'm interested in finding out as much as possible, for example 'how does the 2/3 port solenoid work' so that I can stop asking stupid questions like

'if the solenoid is acting up (e.g. needs cleaning) does the car over or under boost ?'

'Can loss of boost via a leak in the pipework cause lean AFR ?'

'Does fitting an uprated pump and regulator need a re-map ?'

Thanks,

Mark

 

Err - is that no then ? (Or is everyone busy getting ready for shootout ...)
