Question on switching from MBC to EBC

[Douggievee]

The previous owner of my car had a TurboXS MBC installed, right now holding around 10.5 psi from what my AP is telling me. I'm ordering a Cobb 3 port EBC and I was wondering if this is something I can just install and let the ECU adjust how it wants until I start working with my E-Tuner or if I should hold off installing until I'm ready to load the new tune on there?

3 port requires tuning while 2 port doesn't.

OK so waiting for my tuner to have a base tune set before installing it is best?

To take full advantage of the EBCS it should be plumbed in interrupt mode. This requires re-working the WGDC table.

So yes, might as well wait until tuning time.

How exactly can i hook this up as a 2 port while making it easy to change over to a 3 port? Im trying to install this tomorrow without the tuning for the time being but will change it to 3 port in a month or so. Im just not sure which of the 3 ports not to hook up

Cobb has a document showing how to set it up on their site.

These are the 3 port interrupt setup instructions.

You can run this solenoid in 2 port mode.

All you need to do is to cap off port 3 and then just connect the port 2 to your turbo inlet pipe and port 1 to the top port on your wastegate actuator.

Make sure the bottom port on the wastegate actuator is still attached to the compressor housing barb at the bottom.

Here's a diagram of setting up a 3 port in 2 port mode:

Oopps sorry! I just copied the link I had on my favorites bar from when I installed mine. I thought those had the instructions for 2 port and 3 port. Now that I think about it, Grimmspeed's instructions has the instructions for both.

My bad. Thanks for the save @Lex;

Thank you everyone. That's a big help.
