Single port, twin solenoid, twin turbo connection Method
(For V configuration twin parallel turbocharger engines E.g. V6, V8 etc)
Port 1 of solenoid vent to atmosphere
Port 2 of solenoid to bottom port of wastegate
Port 3 of solenoid to Pressure only source
Join the wires from both solenoids together (polarity not important) and then connect them to the brown and grey wires of the
wiring loom
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
