You mean the electric plug? Leave it open.

Any ill effects to rendering that stock contraption useless? Pressure in the gas tank?

I feared it, researched it, and the conclusion was its being done for long years on tons of cars and no one has reported any ill effects at least that I could find.

I installed my Grimmspeed ebcs! I just want to make certain I connected it properly:



Can port 3 be vented to atmosphere?

Also why is this install diagram different than the one above?

There is more than 1 way of configuration. Read this site for a full explanation:

VTA is fine, just point it down so water wouldn't get inside.


Edit, sorry its late - But do make sure you connect it properly. The one that would normally go to the "intake" can be left unplugged where as the turbo compressor boost reference and WG "bottom" nipple both need to be connected at a minimum.

I found this too. I called GS about it. They told me the simpler VTA way is the one they use and recommend . I've learned the advantage if the more complicated one is a few RPMs of faster spool.

For running say under double the WG spring pressure, I wouldn't bother with the top diagram that adds a tee. I would stay with the simpler VTA mode. It has work good for me.

I have it set up like the top diagram. As I understand it, during spool up, boost pressure is direct to both the bottom and the top of the WG. The result is that the pressures cancel eachother out and the spring is the only one holding the wastegate piston shut. This does not help spool up.

To help spool up, pressure going to the top of the WG must be higher than pressure going to the bottom of the WG. This would help spool up.

Could one put a MBC in the line going to the bottom of WG to STOP pressure from pushing up on the spring (untill a set psi is reached)? This would allow full pressure to push down on the spring untill the set PSI is reached.

This would actually help spool up if the wastegate valve is actually being cracked open by the exhaust gas pressure.

Honestly haven't thought about it, and your explanation seems correct. I just said it from real world experience, same car only change being the EBCS configuration. Would be a good option to explore what you propose.

This is what we need to do

There are also 4 port solenoids that i believe do something similar @jamesm

[Shit Luck]

You guys are confusing the shit out of the old school guy here...

Yeah sorta like a 4 port, the basic idea being that you use boost to help the spring keep the gate shut (whereas with a 3 port you're creating and then manipulating equilibrium between the top and bottom of the gate, and a 2 port just bleeds pressure from the bottom side of the gate). You can accomplish this with a single 3 port solenoid, but there are drawbacks. Mainly very touchy boost control and a significantly higher base pressure over the rated spring pressure. It works, though. I ran my 3 port in that sort of configuration for a while.

My old Blitz connects to the top of the EWG with the pressure source connected to the bottom. It lets the positive pressure help keep the WG closed and bleeds off that pressure to let the WG open to control boost. Or you can hook it up the other way and have it just bleed from the bottom and leave the to unhooked, which is similar to how an IWG would work, it has a setting to change the type.


Basically same setup as the GS has.

I am curious on how you routed this as I have gone over it time and time again just to see if I could figure out how to do what a 4 port does using a 3 port solenoid. haha
