When using the GM 1997152 solenoid with an external wastegate, AEM recommends plumbing
the vacuum (boost) lines like the following:
The next step in creating a new setup is determining what frequency the solenoid needs to be
operated. This information is typically provided by the manufacturer of the part. Both AEM and
GM solenoids are optimal at 31Hz. If using a plug n' play Infinity ECU with a factory boost control
solenoid, this comes pre configured by AEM.
The default Infinity PWM output for boost control is LowsideSwitch_2 (Pin C1-17). There are two
wire connections for a boost solenoid and there is no polarity. One wire connects to 12 volt
switched power and the other will connect to Infinity Pin C1-17.
