The HKS EVC is the 5th generation of HKS’s race proven Electronic Valve Controller series of boost controllers. The current version of the EVC is the first boost controller to feature integrated CPUs in each component (Display Unit, Control Module, and Stepping Motor) for more precise control, quicker response and improved boost pressure stability.

Part # 45003-AK005

The HKS EVC has improved boost stability for maintaining pressure at high RPMs providing increased top-end power, and a new mapping feature allows boost pressure to be precisely tuned for throttle + RPM (or vehicle speed). The new EVC also offers a selectable kPa or PSI unit of measure, and a unique warning feature where if over boosting occurs, boost pressure can be programmed to drop to a user preset level.

The EVC EZ II is the most simplified version of HKS’ electronic boost controllers, but still utilizes the same proven stepping motor as the EVC. With the same "state of the art" closed loop stepping motor, you are insured the same accurate and stable boost levels. Boost pressure will rise faster and earlier in each gear and be maintained without fear of over-boosting. Also the EVC EZ II is capable of being upgrade to a full EVC unit by simply adding an EVC Display unit.
