Figure: Installation diagram for 2-port bleed mode setup.
12. In bleed mode, you will only be utilizing two of the three ports on the BCS. Port 3 should
be capped to prevent un-filtered, un-metered air from entering your inlet when you’re not in
boost. To do this, use the included fitting, cap and a small piece of vacuum hose.
Alternatively, you may source a smaller cap for the fitting.
Installation for MazdaSpeed6:
1. You will be installing the GrimmSpeed solenoid on the firewall above the turbo. You will
be using the existing two factory studs. Place the provided rubber washer on the left stud
and the rubber grommet on the right. Install solenoid on studs. Using the provided nylon
locking nuts, tighten bracket.
2. Follow MazdaSpeed 3 instructions starting at Step 8.
