Dual Port Actuator MBC on Single Port?

[dsmzoom]

Well I messed up big time, I couldn't figure out why my boost controller was so hard to find the desired boost level and I know I hooked it up correctly. So I did some research and the site that I ordered this MBC(turbonetics) from didn't tell me its for dual port actuators only. I was wondering if I could find a way to make it work. The diagram shows vacuum side of the mbc is supposed to go to the vacuum port on the wastegate and the boost source hose is supposed to go into the boost port of the wastegate and that hose also has to be tee'd to the boost pressure sensing connection. I messed up big time and I can't return it cause I already installed it, but if i can't find a way to make it work, I guess I will swallow the 90 clams for my idiotic mistake.

+1. There should be no reason why that boost controler wont work for you. The only ting the other line would do is tell (a gauge or other module) what the boost level is. just set it up, minus the 2nd line, cap it off if you need to.

This is what i bought http://www.turboneticsinc.com/products/index.php?products_id=16&category_id=2

I have it the pressure source hooked up to the fitting where the BCS hose used be on the turbo and the vaccuum hose hooked up to the wastegate. but that diagram is way different then mine. I have 4 ports and they want you to plug up the one on the front and the one on the back and screw in the fittings on the two side ports

Oh I see. Hey, whered your pciture go?

Looking at http://turboneticsownersclub.com/turbos/mbcinstall.pdf, and if I remember your original picture.

Boost pressure sensing connector goes on a nipple or whatever AFTER the turbo. or, on the turbo, if its a t25. anyway, thats the line that will be pressurizing it.

Instead of T'ing it to the MBC AND the WG, just run the line directly to the MBC.

Then run the other line to your WG like normal and it should work fine.

plug that front hole like it says.
