Two port, single solenoid, single turbo connection Method (1)
(For controlling boost on a single turbo, single wastegate, single solenoid turbo system with high back pressure)
*NOTE: An increase in your minimum boost pressure is expected when using any of the 2 port connection methods. Ensure all boost
set point values and gate pressure values are set to Zero and measure the new minimum boost pressure achieved by this method
before increasing your Boost Set Point values.
 Connect the bottom port of the wastegate and Port 1 of the solenoid to a Pressure only source via a tee piece
 Port 2 of the solenoid to the top port of the wastegate
 Port 3 of solenoid vent to atmosphere
Two port, single solenoid, twin turbo connection Method (1)
(For controlling boost on a twin turbo, twin wastegate, single solenoid turbo system, on a straight configuration engine with high back
pressure)
 Connect the bottom port of the wastegates and Port 1 of the solenoid to a Pressure only source via tee pieces
 Port 2 of the solenoid to the top port of the wastegates via tee pieces
 Port 3 of solenoid vent to atmosphere
 Block off other turbocharger pressure port (if needed)
