Ari asked me for my boost control settings for EFR. Figured I'd post them here. These work well for me on high-boost wastegate. With other wastegates and boost targets you may need to tweak them.

I route my wires in front of the engine behind the timing belt, along with crank sensor. It's not a problem. and I can easily unhook the EBC connector.
Make sure you connect the solenoid correctly

The electrical connector is a Bosch EV1 pigtail

Red wire +12V, black wire wired to BOOST on MS3X or whatever boost control pin you use.

Sorry to bump a super old thread, but the useful part of the OP has disappeared. Since this is the first hit in Google for any combination of EFR and EBC, @soviet , could you please re-post?
