Boost Solenoid Wiring

TB123 · Post by **TB123** » Tue Jun 17, 2008 8:47 am

I am working on installing my boost solenoid. The instructions say to wire it into the ECU using A11. My ECU (P72) has an empty slot at A11. Do I need to add a pin to connect the wire? How can I do this? Thanks.

You will have to add a pin to the harness and run the wire to the solenoid. The boost component kits sold through our dealers include the needed pin.

Are these the pins? They don't seem long enough to fit through the harness.

yes those are the pins. they looks short but the other side of the pin reaches it.

With the ignition key turned forward should I be getting power on both leads going into the EBC? I'm running the synapse wastegate 40mm unit. No matter how I run the plumbing I cant get any type of increase in boost JUST ON THE 2 PORTS OF THE EBC

Here is my map, any idea's Blundell tuned my car on 15psi via wastegate spring and it's preload adjusted. But preload is backed all the way off and I'm at 12 psi even if I set the Base at 75%

Help

You either have an error in the wiring or in the plumbing of the vacuum lines. Double check the insturctions and what you have done. If you still don't see a problem, have someone else look at it as that usually helps spot the problem.

I still need to know that with that setting in the Boost Controller screen, if I would have power on both leads at the EBC?

Yes you will get voltage from both wires if you have it connected to a 12v power source.

Talked to Blundell today and he told me to try the HARDLINE method to see if it's something wrong with the ECU or the valve. I connected one line to the positive battery terminal and the other to the negative terminal, set the boost cut to 20 psi "base is 15psi" and went for a run. I still have no increase in boost. Is it possible I got a malfunctioned controller

Does the solenoid buzz if all parameters are met when proeprly installed? If not, it is either a wiring problem or you don't have the components installed in the ecu correctly.

I popped open the ECU and checked/ rechecked/ and tripple checked, then has a EE at work check it. It's all there and all solid. Pin is in A11 and I've tried all methods to get the solenoid to work. I'm going to redo the wiring to where I can have in in my lap with no lines and go out for a run.

today while on the dyno, we found out the person that soldered my ecu installed 1 transistor backwards, therefore boost controller couldn't go past the spring. make sure you check everything. If you don't know send it to someone who does know
