adding my manual boost controller

hi guys i have bought a manual boost controller from ebay to help with my boost cut problem,
simular to this one

any ideas how to fit it,
this is a photo from my enginebay


im guessing this is right

1)from turbo
2)restrictor pill
3)wastegate
4)goes to 2 port solenoid
5)t piece

i know it has to go between the turbo and wastegate but where? and what way around?
any help would be great
thanks guys

Re: adding my manual boost controller

you could just get to the bottom of you problem rather then mask it

Try a Fuel cut defender made by HKS from memory, I ran a decat on a classic with no issues.

Re: adding my manual boost controller

after looking at your picture id throw my hat on the fact you haven't got a restrictor pill fitted now the hoses have been swapped.

Re: adding my manual boost controller

What’s the Common Causes For Overboost
Decat + High flow induction – Cure ( Reduction of the solenoid duty cycle or alteration of restrictor size will help return boost output to its normal level)
Split, poor fitting, or disconnected pipes – (Cure replace or refit pipes, the pipes that will cause this issue are between the wastegate actuator, solenoid (including upto the restrictor on the return pipe of the 3 port solenoid) and the turbo.)
Manual Boost Controller – Electronic Boost Controller set too high – Cure (Dont be so greedy and back the boost duty/adjuster off to a safe level smile.gif )
Restrictor Pill not fitted / size incorrect – Cure ( Ensure restrictor pill is fitted (3 port) if so on a 3 port reduce the restrictor size and on the 2 port increase the restrictor size to reduce the boost to a safe level)
Clogged 3-port solenoid It is possible that the flow of air through the 3-port solenoid could be restricted between the turbo outlet port and the wastegate actuator port if the solenoid is very dirty (usually oil vapor from the intake system), this allows the wastegate to remain clamped shut longer than it should be causing a potential overboost situation. Cure (Clean with carb or clutch/brake cleaner)
Loss of solenoid funcation Although this is not Overboost it shows itself with very simmilar symptoms, its an interesting senario I had brought to my attention today ( Thanks Mark wink.gif ), is it is possible for the solenoid to fail or even stick shut whilst under boost, this would result in a rapid reduction of boost pressure to wastegate pressure approx 0.5 BAR , so if you were running at full boost 1.0 BAR for example and the solenoid was to fail shut it would feel just like Overboost as the wastegate rapidly opens due to the solenoid blocking off the spill from the wastegate. Cure (Either clean the solenoid with carb or clutch+brake cleaner or replace the solenoid)
