Anybody know why I can't get my manual boost controller to control my secondary boost. I've used 2 controllers 1 from primary the other on transition, bypassed solenoid, made sure arrows face actuators and made sure dial is to 'boost -'
Really annoying yet probably somethin simple
Thanks

 

How exactly do you have them installed? Pictures of your routing would do wonders.

For MBC's, remove the line that runs from the compressor to the actuator and install the MBC, then run another line back to the actuator. Take the other line off and cap the other nipple on the actuator. Then remove/cap that line you just removed.

Here's an example of what I mean from the EVC EBC install:

This is how my set up is. Sorry for no pictures phone won't let me upload

 

That diagram is very confusing. Basically, what it is doing is openly venting any pressure it sees back through the light blue line.

Follow the arrows on my modified picture. Essentially any air you send to the wastegate or precontrol will simply flow right back through the piping into the inlet duct. This would make the wastegate nearly completely inoperable. Unless I'm missing something, that would be VERY unsafe.




To remedy the situation, simply remove the green and orange lines coming off each actuator (that runs to the stock solenoids) and cap them off with some good quality caps.

 

Ok thanks, I'll give it a try.

 

Cheers mate, you were spot on.
Capped the 2 lines and it worked brilliant.
Thanks for your help

 

Glad to hear, I've seen that diagram for years now, never realized it didn't actually work.
