Line 20:

The actuation of an electronic boost controller can be managed by one of two control systems:

* [[Open-loop]] is the simpler option, where control output is merely based on other inputs such as throttle angle and/or engine speed ([[Revolutions per minute|RPM]]). Since an open-loop system does not include any monitoring of boost pressure, the boost pressure may vary based on outside variables (such as weather conditions or engine coolant temperature). For this reason, open-loop systems are less common.{{citation needed|date=April 2022}}

* [[PID controller|Closed-loop]] systems rely on [[Feedback loop|feedback]] from a [[Manifold Absolute Pressure sensor|manifold pressure sensor]] to maintain a target boost pressure as closely as possible. These systems are more sophisticated and can more accurately control boost pressure under varying circumstances.
