Guys i need some advice, this is the digram i have come up with for installing the manula Bosst Controller,
buti cant cant figure out why the T Peace is needed or if it is is my diagram wrong
(http://www.ocgamer.co.uk/img/GTi/Parts/MBC.jpg)
The Ball and spring is in the "T" but i dont see how the dial controles it... and is the T actually needed, can i just need run the controller between the wastegate and turbo housing?
Normaly i can look at these things and figure them out, but if connected them up on the bench and ran a foot pump to the controller and some hoses with a gauge to see what happens.
i can controll using just the controller, buti can make any changes in pressure using the T?
Please Help!!

why are you wanting to run an MBC in the first place?
-
I need to mkae sure the N75 hasnt died.... so this was supposed to be a quick plumbin and test to see if i get the same reults or if the boost holds steady, if steady then i know the N75 needs replacing.
I need to fix this quick as its booked in at R-Tech on th 7th for a stage 1

be quicker to get someone local to swap an N75 with for 10 minutes, and cheaper.
If the N75 was faulty you would have a fault code
-
I would, if i had someone to swap one with... :wink:
dont know any GTi owners yet near me who are friendly
-
Yes that is the correct setup. Also a faulty n75 doesn't always give a fault code. If you set the MBC too high your car will keep hitting limp mode

or worst case go pop

this is why a never let revo near my car as they wanted 1 fitted before mapping it :grin: nick and ben @ r-tech had a wee laugh about that idea

Dude, that would have been cool... but my N75J has arrived :)
and i found that with heatsoak the valve was sticking and a blown breather pipe allowing in air pass the MAP... All sortedand she runns like a beast :D
so ool, ive even boughter her a new badge "The Interceptor" and after Tuesdays trip to R-Tec she truely will be...
I have such big plans for her, she will eat Ford's, Mig's and Scoobys for breakfast
Also gave up with the MBC as i could not get the damn thing to regulate boost, no matter how or where i installed it :/
-
Just as a warning, R-Tech won't map it with the J valve fitted
-
They will certainly prefer the latest revision from the dealers. E, F or G whichever is latest revision now. Older valves are less responsive so the ECU/valve takes longer to react so you get a touch more boost before the valve steps in.
Go to dealers, spend £40 and get a good working valve on your motor.
