HKS EVC VI Electronic boost controller - Valve controller 

Use: Boost controller - Automotive Turbocharged Engine  Application: Vehicles that operates on a DC 12V negative ground.

Remarks.

• A fuel controller (E.G F-con, AIC, etc) may be needed when raising boost pressure with the HKS EVC boost controller.
• when you install in the proppet valve/twin turbo/ 4 hose piping car. respective hose set of the selling separately is needed.
• Some vehicles have a fuel cut function when boost is raised. To bypass the fuel cut function, a unit such as the HKS FCD. a fuel controller may be required for additional fuel tuning.

The HKS EVC enables the adjustment of the boost setting from inside the vehicle. Utilizing a stepping motor, it simulates boost increase and attains the designated boost valve without over-shooting. This product was developed to improve engine output and was designed to be used for racing in a closed circuit. Improving engine output may affect oil and/or water temperature and oil pressure. to preserve engine performance, regularly monitor engine conditions before driving.

To use this product on public roads. follow the necessary procedures if there are any regulations for a tuned/modified vehicles.

• Compact design: Its compact designed display and stepping motor enables a versatile installation into the vehicle interior and the engine compartment.
• Wide boost range: The boost level can be controlled from baseline boost to 250kPa (36.0PSI)
• Simple boost setting: Just directly input the desired boost value to modes A and B, and let the HKS EVC control the boost
  
• Return Function: Once EVC is turn ooff, the boost level returns to the baseline value. For some vehicles the boost may become lower than the stock settings after EVC is off
• Scramble Function: With the scramble function, the boost can be increased by a designate value avobe the set boost value. The increase in boost is obtain while pressing button 1 of the display or the optional external scramble switch (using the provided harness). The time span of the boost increase after the release of the button can also be set.
• Dual Offset Mode Settings: If the desired set boostand the actual boost levels do not match, the offset function can be used to adjust for the difference. The offset of both A mode & B mode can be set individually; therefore, more precise results can be obtain.
• Warning Funtion:  if the boost exceeds the user selectable warning value, the EVC notifies the user with an audible beep and visible warning display. Simultaneously, it lower the boost value or by user preset value. This funtion prevents damage to the engine and/or the turbine due to over-boost.
• Throttle Positoin Input: With the throttle position sensor input, boost characteristics can be tuned in relation to throttle percentage.
• RPM Signal Input: With the engine RPM signal input, boost characteristics can be tuned in relation to RPM level. This feature works on engines from 1 to 8 cylinders and operates up to 12,000 RPM 
• Map adjustment function: Input of the throttle signal and the engine RPM or vehicle speed signals can draw a 3D mad enables the easy control of the boost characteristics.( the setting range must be within +/- 120kPa (17.0PSi) to the baseline boost setting.) This function is user selectable to be on or off.
• Digital Triple Data Meter: 3 digital data readings of surge tank pressure, throttle percentage, and engine RPM vehicle speed can be displayed.
• Bar Graph Selection: The bar graph display can be set for boost, throttle percentage, engine RPM or vehicle speed
• Bar Graph peak hold function:  The peak hold function of the bar graph displays and holds the maximum value achieved for easy instant recognition.
• After Image Display function: When the boost changes from positive pressure to negative pressure, the maximum positive boost value is displayed for a few seconds. This function is user selectable to be on or off.
• Intial Set up: The boost quality due to the individual difference of the turbine and car is recorded semi automatically, it does the control which is agreeable to the vehicle.
• Data Memory Function: All set values are saved in the internal memory of the EVC. Therefore, these settings are not lost when ignition is off or if the battery is disconnected.
• Exhaust Bypass (Watergate type) Selection: The EVC can work with both internal and external watergate type.
• Pressure Unit of measure Selection: the unit for measure for pressure can be selected between KPa or Psi.
• Dimmer Function: The brightness of the display unit is adjustable
• Data lock function: To prevent accidental change of data settings. The unit can be locked with a code
• Large Multi-Display: Utilizing a large positive display enables clear day and night viewing. The multi-display also enables simultaneous data recognition.
• Digital and Analog Boost Monitoring: The digital data and the bar graph can allow the dirver to read and understand the boost conditions intuitively and visually.
