greddy profec b2 over boosting

[jonn421]

hi need some help please, fitted a greddy b2 boost controller at the weekend , and its running unlimited boost even when turned off checked all pipes for leaks, checked every thing is where it should be. only thing not sure about is you use only two outlets on the solenoid ,do you need to block up the other one,any advice would be great thanks. jon

You leave the 3rd outlet open.

Also make sure you have:
a. Used the correct 2 outlets
b. Have them connected the right way round
c. The controller unit is registering the boost level
d. You've disconnected the pipes to the standard solenoid and bunged up the pipe from the standard solenoid that goes back to the air intake to stop entry of unmetered air.

The pipe to the actuator should go to the COM port of the greddy solenoid.
The pipe from the plenum or wherever else you're taking your pressure source from should go to to the NO port of the greddy solenoid.

The page marked "8" (page 9 of the PDF) on the below manual is what you should be looking at, the setup before this one in the manual does not apply to the R.

thanks graham checked all the above and all ok,controller is measuring boost level could it be the solenolds not working, strange not getting around 0.5 bar when switched off, checked actuator arm had`nt come off ,maybe try old solenoid and piping back on see if its still doing it. shall let you know cheers. jon
