Auxiliary outputs
Example 2: the second way is to connect the boost solenoid to the
top of wastegate.
Select the output signal as activated at 12V and frequency at 20Hz.
This way, the boost valve will increase the pressure at the top of
wastegate to increase boost

Wastegate integrated to the turbine
This valve has a different operation system, as it relieves the boost
pressure when pressure is put on its top part, which is the opposite
of what happens to the wastegate installed at the exhaust manifold.

Select the output signal as activated at 0V and frequency at 20Hz
With this kind of wastegate, the boost valve relieves the pressure in
top of wastegate to increase boost pressure
14. Electronic throttle control
