BOOST CONTROLLER

EVC-S

Reasonable functions for reasonable price.

Traditional HKS EVC series.
Ultimate basic model.

HKS released "EVC-S" from the EVC product series for price-conscious customers.
This EVC-S utilizes the solenoid valve. The original EVC's complex functions were simplified and contained in EVC-S. It works for both internal and external wastegate types. Junction connection system that connects the display unit, solenoid valve, and boost sensor to the control unit is utilized for simple installation. Appearance of the display unit was designed to match well with other HKS electronics parts.

  • Warning, Drop boost functions
  • Peak hold, after-image indication functions
  • Applicable for both internal and external wastegate types
  • Stock boost recovery function when power is off

Advanced Features

  • Compact Size / 4 Separate Units
    EVC-S includes 4 separate units: Display Unit, Control Unit, Boost Sensor, and Solenoid Valve.
    Each unit is compact and easy to install in the engine bay and the interior. Since the Boost Sensor is independent, hose routing does not need to run into the vehicles interior.
  • Capable of Controlling High Boost
    EVC-S can control up to 250kPa (36PSI)
  • Simple Boost Setting
    Directly input simple values to modes A and B, and let the HKS EVC control the boost.
  • Return Function
    The boost setting returns to the factory setting when the power is turned off. On some vehicles, the boost value may be lower than the boost before installing the EVC-S.

  • 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. This function can be turned off.
  • 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.
  • Boost Unit of Measure Select Function
    The boost unit of measure is selectable between kPa and PSI.
  • Data Lock Function
    The setting data can be protected by a password to prevent unwanted or accidental changes.
