Electronic Boost Controller protects the lifespan of turbocharged or supercharged engine vehicles. The boost controller primarily controls the air pressure presented to the wastegate actuator. Further control and intelligent algorithms can be introduced to refine and control over actual boost pressure delivered to the engine. The air pressure pushes against the force of a spring located in the wastegate actuator to allow the wastegate to open. The opening of the wastegate before the desired boost pressure will cause the threshold of boost onset and also increase turbo lag. The boost controller will assist in reducing turbo lag and lowering the boost threshold. Boost pressure builds faster when the throttle is depressed quickly and allows boost pressure to build at lower engine RPM compared to a car without such a system.
