So I'm ready to turn up the boost on my MKturbo. Like the title states I've got a Brain built MS3X and I think all I need to buy is the EBC solenoid from DIY Autotune, can anyone confirm or did I need to specify to him I wanted EBC when I ordered it? (I know I would have to pay extra for the solenoid but not sure if the MS had appropriate mods already installed)
I would PM Brain himself but I know he gets tons of messages and I'd like to order what I need asap.

 

When I bought mine, I didn't specify. But then again, I did reach him through MiataTurbo.net with the intention of putting a turbo on my car. VVT was also available before I had switched to a VVT head. Some of these things may just be populated by default. You can check to see if Pin 6 is used on the DB37 expansion connector (see below) You might be also to just look for the printed wire and find one that says boost and see which pin it runs to on the auxiliary connector.

I ended up harvesting and reallocating some old unused MAF wiring to use for my EBC.

 

I'd be surprised if your unit isn't already prepared for ebc. In which case yes all you'd need is the solenoid

 

EBC output is wired into your MAF/AFM connector as per my docs...

Most likely pre-wired. Mine was.

 

Thanks Brain I went back several times to your docs and figured it was there but kept second guessing myself and wanted to make sure. Thanks again for a great unit.
