Just because , did you keep the Greddy solenoid? I replaced mine with an aftermarket just in case. Wanted to start out fresh. Can't be wiring because the polarity doesn't matter when splicing to the evap.

Its actually a innovate SCG-1. I'm not 100% what solenoid it is but it is still on the car. After reading more threads and remembering my EBC didnt work properly. I'm beginning to think that this is a plumbing issue. I plumbed in the vacuum lines per sashas instruction manual. I had a shop do the boost controller plumbing after. I'm wondering now if the reason my tuner could never get it to function properly was because it was plumbed incorrectly. Still somewhat abnormal considering the car ran great for a while after it was tuned. If the WG springs and 02 sensor doesnt cure my boost creep problem I might just have the boost controller solenoid removed and the plumbing completely redone.

My setup with boost by ECU has only one vacuum line teed going to the lower wastegates from the solenoid. Previously on the EBC it was this. ( very easy for you to verify on your own.)

How does Ecutek control the solenoid? Do you have to wire it into the ECU?

My EBC is plumbed (not sure if my ports are the same on the solenoid) the same way as yours but obviously my solenoid runs to my controller.

The signal to the Evap control solenoid is hijacked and the signal sent to the boost control solenoid. Simple splice of the two evap solenoid wires redirected to the boost solenoid.

I always wondered how that worked. That’s pretty simple and wouldn’t require me ordering anything else assuming you can use any solenoid.

I assume the solenoid is just a milliamp signal that translates into percentage open.

Yup initially I used the Greddy solenoid but switched it out for a new one. Just two wires and done. The only other item was a 4bar map sensor.

That’s a plug in from the Juke sensor, right?

Not sure I got mine from Seb.

As I save up money for the parts I need i'm just trying to tidy up some things. I have a relay in the battier with a green light; It has two blue lines, a black line and a red line. Can anyone tell me what these lines are for? I can see that one red line goes to the battery with a fuse and is junction to run the the relay and pump. The black is junction and runs to the ground on the battery. One of the blue goes no were and the second one is junctioned to a yellow wire. thanks in advance.

P.S. I also don't see any of this wiring in the the BP manual.

Are you referring to the fuel pump relay or the exa pump?

It could be the fuel pump relay. It has a green light on it and it is in my pictures above. I found a blue wire not even connected was trying to make sure it was wired correct.

I don’t see any pictures unless it’s pages back.

Boosted Performance · 02-17-2019, 11:19 PM

With the fuel pump relay, there are two wires that go to the fuel pump, one to ground, and another to the battery.

If you have a picture, please post it or send it to me and I will tell you what goes where.
