mattdavies Posted April 5, 2012 Share Posted April 5, 2012 I have installed a Greddy profec boost controller on my car and went out for a little drive, while driving it was boosting over 15psi even when on the lowest boost setting. Just want to check on my solinoid there is an 'IN' and 'OUT' does the out go to the actuator and the in from the turbo side. As this is the way i had it ? I need to know if the boost controller is faulty as i bought it second hand Quote Link to comment Share on other sites More sharing options...
FOSTA Posted April 5, 2012 Share Posted April 5, 2012 Yep the boost signal (vacume) would come from the turbo to the in port the out port to actuator / wastegate. I don't have the greddy boost controller but I know the solenoid reduces the signal that the wastegate see's so that would be the way it needs set up Quote Link to comment Share on other sites More sharing options...
mattdavies Posted April 5, 2012 Author Share Posted April 5, 2012 Ok, i believe it is meant to be set on actuator but am i being dump and should i have it set on wastegate ? Quote Link to comment Share on other sites More sharing options...
FOSTA Posted April 5, 2012 Share Posted April 5, 2012 Is yours stock twins? If so Im 99% sure it will have an internal wastegate that is controlled by the actuator, there for you would connect a vacume to the out port to actuator. If it's a single turbo I'm gussing you will most Likly have an external wastegate so the out port vacume would connect to the wastegate. Hope these help Quote Link to comment Share on other sites More sharing options...
mattdavies Posted April 5, 2012 Author Share Posted April 5, 2012 Thank you, i have it on actuator ( overboost) and have re-read the manual and think i understand abit more now so will have another play probably tomorrow Quote Link to comment Share on other sites More sharing options...
JODY T Posted April 6, 2012 Share Posted April 6, 2012 Remember a BC can only lift boost it can't lower it from what the car naturally wants to boost at.. Are u decatted? What restrictor ring you have? If 1.2 then the BC can't do anything.. Get a 1bar one and then set up BC to lift from 1 to 1.2 Quote Link to comment Share on other sites More sharing options...
