Boost Controller‑ Automotive Turbocharged Engine
Vehicle that operates on a DC 12V negative ground.
４５００３−ＡＫ００５
・ A fuel controller (e.g. F‑CON, AIC, etc) may be needed when raising boost
pressure with the EVC Boost Controller.
・Some vehicles have a fuel cut function when boost is raised. To bypass the
fuel cut function, a unit such as the HKS FCD can be used. When using an
HKS FCD, a fuel controller may be required for additional fuel tuning.
Read this instruction manual prior to installation to ensure safe and correct usage and
optimal product performance,

Introduction
−１−
The HKS EVC enables the adjustment of the boost setting from inside the vehicle.
Utilizing a stepping motor, it stimulates boost increase and attains the designated
boost value 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 vehicle.
●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 HKS EVC
control the boost.
●Return Function
Once EVC is turned off, the boost level returns to the baseline value. For some
vehicles, the boost may become lower than the the stock settings after EVC is off.
●Scramble Function
With the scramble function, the boost can be increased by a designated value above
the set boost value. The increase in boost is obtained while pressing botton① 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 botton can also be set.
●Dual Boost Mode Settings
Ａ Mode & Ｂ Mode are the 2 user specified preset boost level selections. Each mode
can be used for a different purpose or situation.
www.R33-GTR.org

●Dual Offset Mode Settings
If the desired set boost and 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 obatined.
●Warning Function
If the boost exceeds the user selectable warning value, the EVC notifies the user
with an audiable beep and visable warning display. Simultaneously, it lowers the
boost to the baseline boost value or by a user preset value. This function prevents
damage to the engine and/or the turbine due to over‑boost.
●Throttle Position Input
With the throttle position sensor signal 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.
●Speed Signal Input
With the vehicle speed signal input, boost characteristics can be tuned in
relation to vehicle speed. This feature works on applications that utilize speed
pulses between 2 to 16 and has a maximum speed capacity of 500km/h.
●Map Adjustment Function
Input of the throttle signal and the engine RPM or vehicle speed signals can draw a
3D map by using 2 these signals as axes. Using the 3D map 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
or vehicle speed can be displayed.
●Bar Graph Selection
The bar graph display can be set for boost, throttle percentage, engine RPM and
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.
●Data Memory Function
All set values are saved in the internal memory of the EVC. Therefore, these
settings are not lost when the ignition is off or if the battery is disconnected.
●Exhaust Bypass (wastegate type) Selection
The EVC can work with both internal and external wastegate types.

Safety Precautions
Below are symbols used in this manual to highlight areas where .
Warning ‑Risk of severe injury or death may result if
warning is not acknowledged or followed.
Caution ‑Risk of injury to self, damage to vehicle or
property may result if caution is not taken.
Warning
●Make sure to work on the vehilce in a well‑ventilated area to prevent
possible explosion or fire.
●Do not mount the unit where it can distract driving.
●Do not install this product on a 24V vehicle. It is designed for use on
a 12V vehicle.
●Make sure to remove the cable from the negative terminal of the battery
to avoid possible damage to other electronics during installation.
●Make sure to hold connectors when removing them to avoid possible
damage to other electronic parts caused by disconnections or by a
short circuit.
●Stop using the product if any unusual conditions are noticed; it may
cause a fire or an electrical shock. Consult an authorized dealer
immediately.
●Do not operate the EVC while driving to avoid the possiblity of an
accident.

Caution
●Do not install this product by yourself unless you know how to use the
tools and equpiment necessary to safely perform service operations on
your vehicle
●Do not modify, disassemble and/or remodel this product and any of its
attached parts.
●Handle the parts with caution at all times.
●Avoid allowing oil and/or water from entering the unit. It may cause
damage to the engine.
●Prior to installation, make sure that the engine bay temperature has
cooled. Failure to let the engine cool can lead to severe burns.
●Select the appropriate exhaust bypass type. Selecting the wrong type
may cause damage to the vehicle.
●Install the unit away from excessive heat or water to avoid possible
malfunction and damage to the engine.
●Do not tie or bundle a vehicle fuel line with any of the other hoses
and/or harnesses. It may cause severe damage to the vehicle.

Features and Functions
１. Features
１．Button ①
Use this button to activate the scramble function in the standard mode. While pressing
this button, the scramble function is activated. When the scramble function's timer is
set,the function starts working when the button is released. If the set value is blinking
in the speed axis set mode, RPM axis set mode, throttle axis set mode, map correction
boost A/B set mode, or map offset A/B set mode, this button is used to select between the
set axis and the set value.
２．Volume Knob
In the standard mode, pressing the volume knob for more than 1 second resets the peak
value. Turn the knob left to switch to boost mode A and turn right to the mode B.
Pressing the volume button in each mode makes the set value blink or turn it on. When
the set value is blinking, turning the volume knob to the right increases the value; and
turning it to the left decreases the value. In other modes (aside from standard mode),
when the value is blinking, turning the button switches the modes in each mode group.
３．Button ②
In the standard mode (when the A/B boost value is not being set) press this button for
more than 1 second to switch the EVC on or off. When the power is on, the EVC control
becomes active. When the power is off, the vehicle returns to the standard boost value
which is not controlled by the EVC. When the set value in each mode is blinking,
pressing this button switches the mode group.
４．Main Harness Connector
This main harness connects the power harness, extension harness, and each signal harness.
５．Scramble Harness Connector
This scramble harness connects the optional external scramble switch.
６．Easy Writer Connector
This connector is for PC communication to make settings with the HKS Easy Writer. (Optional)

of the EVC Stepping Motor.
Advice
・Make the hose length short as possible
・Do not put and oil and/or lubricants on
or in the hose and vacuum filter
・Nipples of the EVC stepping motor must be
facing upward to avoid any oil or water
from entering.
(１)Cut the 4mm and 6mm Hose and connect them
to the respective 4mm and 6mm vacuum
filters as shown in the diagram on the left.
Advice
・Cut the 4mm and 6mm hose to different
lengths so that the vacuum filters are
not in contact with each other.
・Do not pu any oil and/or lubricants on
or in the hose and vacuum filter.
