I'm still trying to wrap my head around why somebody would grin after eating shit.

where exactly is the boost source? what exact port on the EWG? (yes, what you pictured looks correct to my docs, but not to my post)

When you are doctor in your country, I hope you don't start operating because a patient goes "Doc, my foot hurts"

:rofl:

​​​​​You realize that I'm an American right?

The boost source and ewg port are the same as they were pre EBC.

EWG: There's only one port connected on the wastegate which Todd had installed. The second port on the ewg doesn't have a port connected.

The boost source is the IM. The BOV is connected in the circuit with the IM heading to the EBC boost source.

The system is working now. I just need to tune ebc because I keep hitting boost cutoff. The spool is instant which is awesome, but I hit fuel cut the second I put my foot on the floor.

Pretty sure I finally hit 200hp haha.

Nah, he'll cut off both arms and then realize it's not even the right patient

The WG or EWG should never be referenced to the IM. Never. Not ever. NEVER. NOT EVER.

The EWG or WG should be referenced somewhere between the TB and the compressor. It should not ever be on the intake manifold or any of its plumbing. Never. Not ever. No, not even this time. I don't care what she said. Don't do it that way. Don't touch the intake with it. I said no. Stop it. Quit it now or you will be in big trouble. Just wait until your father gets home. Leave the intake manifold alone. Put it in the intercooler piping like everyone told you. Intercooler piping. Right now. Do it. Do it now. I'm watching you. Put the line on the intercooler piping. Put it there now. OK, that's it, mister. You are in so much trouble. You better put it where I told you right now. Do it. Right now. Do it. I'm serious. Do it now.

:bowrofl:

I already posted earlier that I knew it was wrong. I just wanted to get things working while the parts I need show up.

Things are working. So I'm working on things as they arrive and tuning when I have time in the interim. The routing is working. For the moment, I have functioning EBC. I call that a win.

That's not "working." You know it's wrong, just fix it. There's not a single part that you could possibly be waiting on that necessitates you fixing a bad thing in the meantime.

sixshooter 07-17-2017 06:32 PM

WG won't open at part throttle boost and you risk over spinning/over boosting the turbo plumbed that way.

18psi 07-17-2017 06:42 PM

But it makes some seriously awesome noises tho :)

ridethecliche 07-17-2017 08:28 PM

Hm. I hadn't heard any turbo flutter tbh.

I know this because when I drove the car for the first time, I had forgotten to plug in the BOV.

Why wouldn't the WG open?

Wouldn't the BOV be responsible for doing that? I can hear the BOV go off every time I take my foot off the gas.

Like I said, I'm working on it. Car has honestly not been driven all that much in the past few weeks because of rotations. I drive the subie for rotations.

On a learning note: If the BOV is connected to the 'circuit' before entering the EBC, why wouldn't things open? The BOV is responsible for releasing the built up pressure when letting off at part throttle right? So if I let off the throttle, it senses the pressure differential and opens. This is how its been happening anyway. If the BOV was connected PAST the EBC, i.e. on the way to the WG, then I can see having an issue.

Last piece of advice from me, totally serious.

You need to fix your boost source. Then you should disconnect EBC and just run wastegate pressure. I am not going to make any predictions, leave that to 18. However, that is what you should do.

Holt on. Imma draw u a pictor.

The BOV and the WG are 2 completely different systems doing completely different things and have nothing to do with each other.

And they are looking for two different signal sources.
