Need help routing a vacuum line for EWG!
hey guys i need help on routing my ewg. im super confused on the vacuum line. the setup im ordering is a grimmspeed 44mm tial wastegate setup that will be routed to a prodrive ebcs
i found these images online on how i should hook up the ewg to my prodrive ebcs but im kind of confused because from subimods has a different image.
here are these pictures:
and here is how someone on nasioc has recommended that the vacuum lines be routed but the port connections are a different. from being where the vacuum line for the intake connects to the ebcs is different.
and i was thinking that instead of making a "t" connection, i was thinking of routing the compressor vacuum line to the ewg then another vacuum line back up to the prodrive ebcs. if anyone has any input, please i need all the advice i can get.

This is one of the correct ways to set it up. Port 1 is normally open to Port 2 which pushes on the top of the wastegate and cancels out the signal to the bottom of the wastegate from the compressor cover. This allows the wastegate spring to keep the wastegate closed normally. When the ECU actuates the solenoid, it opens port 1 to port 3. This takes the signal away from the top of the wastegate and bleeds it off into the intake. This will allow the signal at the bottom port of the wastegate to open it. In this method, you're basically just controlling the pressure to the top of the wastegate to regulate it. This will give you good control with smooth spoolup but not necessarily the best response.
Another option is to eliminate the T, run the pressure source directly to port 1, run port 2 to the bottom of the wastegate, and run port 3 back to the intake. In this configuration you would leave the top port of the wastegate open to atmosphere. This will give you the ability to achieve better overall response but it may be a bit tougher to tune.
The first arrangement may be better to use with the prodrive solenoid as it has relatively small ports and can have a hard time flowing air quickly enough to fill the relatively large body of the EWG to actuate it. The second configuration is generally used with a larger solenoid body or with an MBC.
Thanks

thanks ed! i went with the open atmospheric setup. i might hit you guys up in the following month for a real protune over the e-tune from clark tuning. i just dont have enough cash to have a local tuner tune it right now! but again thanks!
