Data can be locked with a password; it prevents data loss or inadvertent data changes.

On some vehicles, the boost value may be lower than the boost before installing the EVC-S. It can achieve easy instant recognition.

Each unit is compact and easy to install in the engine bay and the interior. Warning Function If the boost level exceeds the warning value, the unit will warn the user will an audible buzzer and visually on the display.

Input of the throttle signal and engine RPM or vehicle speed signals enables the boost control by a 3D map using 2 these signals as axes. The side of the buttons can be switched by flipping the monitor vertically.

Monitor Navigation System easily leads the user to the correct setting and logging screens. Throttle position sensor signal input enables the boost control with the throttle angle. The boost pressure can be increased by a designated value above the set value.


The proven Stepping Motor is utilized as a valve unit. This function can be turned off.

Redesigning the color pattern of the main display improved the visibility during driving. Unified design for whole HKS electronics products.

Easier installation by separate setup Separated units are connected to the center control unit. Speed signal input enables the boost control with the speed. Also, the boost is lowered to the stock value or a preset value to prevents damage to the engine.

The boost value will be lowered to the set value. Select appropriate exhaust bypass type from swing valve type or poppet valve type. Return Function The boost setting returns to the factory setting when the power is turned off. Thin display unit enables free layout.

This function protects the engine and turbocharger from excessive boost. This ensures more precise setting. All settings are stored in the internal memory; so settings will not be lost even when the ignition is off or the battery is disconnected. Data Lock Function The setting data can be protected by a password to prevent unwanted or accidental changes.

Junction connection system that connects the display unit, solenoid valve, and boost sensor to the control unit is utilized for simple installation. More precise correction is possible for modern smaller sized turbo.

It works for both internal and external wastegate types. The differences between the boost pressure set vj and actual value can be offset in 3 different modes.


Boost pressure setting returns to stock pressure value when the unit is off. Select the display unit’s brightness from 2 levels. After Image Display Function When the boost changes from positive pressure to negative pressure, the maximum boost under positive pressure can be displayed for 3 seconds.


Appearance of the display unit was designed to match well with other HKS electronics parts. If the boost exceeds the warning value, an audible beep and visible warning display notify the user. Select the unit from kPa or PSI. This EVC-S utilizes the solenoid valve. The maximum positive boost value is displayed for 3 seconds when the boost changes from positive pressure to negative pressure.

Select the type of a bar graph from the boost pressure, throttle angle, engine RPM and vehicle speed. Data Memory Function Each setting value is saved in the internal memory; the saved values are retrievable even after the ignition is shut-off or the battery is disconnected.

The bar graph displays the maximum value after it is reached. Boost pressure can be set in 3 different modes to use them for different conditions. Since the Boost Sensor is independent, hose routing does not need to run into the vehicles interior.
