HKS EVC MANUAL PDF

It features negative yellow backlight, where the backlight is black, and the foreground is yellow. Also has 3 bar solenoid, speed-throttle duty tables. And somehow it works via powerwriter software. The EVC V is a user-friendly, full-featured digital electronic boost controller that utilizes a precision "closed-loop" boost regulating stepping motor.

Do not attempt to install or adjust the EVC without thorough knowledge of how this unit works. This manual assumes that you have the knowledge in the operation of tools and equipment that are necessary to safely perform service operations on your vehicle. This manual also assumes that you are familiar with typical automotive systems and basic service and repair procedures. Always have access to a factory repair manual as some of the procedures and specifications required for the proper installation of this product may be referenced to the factory repair manual.

To avoid the risk of personal injury, follow the lifting, supporting, and safety precautions contained in the factory repair manual. The EVC will maintain its programming even if the vehicles battery is disconnected or the head unit is unplugged. The serial numbers must match on the control unit and the stepping motor in order for the unit to function properly.

The EVC is a sensitive electronic component and must be handled with extreme care. Mis-wiring or shock will damage the unit. Do not place near extreme heat, water, or areas prone to dirt and dust. Most factory turbocharged vehicles come equipped with a secondary boost limiting system fuel-cut system or pop-off valve to protect against wastegate failure. Due to this, the EVC alone will not be able to raise the boost pressure beyond the point of the factory limit. HKS will not warranty any damage caused be excessive boost levels.

Make sure the vehicle has a proper fuel management system that can handle higher boost pressures than stock OEM levels. The EVC cannot control boost pressure above the maximum efficiency point of the turbocharger. Boost pressure drop at high rpm may not be totally eliminated. The EVC will not be able to compensate for pressure loss due to turbocharger sizing. Increasing the boost pressure will also increase the intake air temperature.

If the intake air pressure exceeds degrees Fahrenheit deg. Celsius , performance increases may be minimal and detonation may occur. For best performance and to safeguard against detonation, always use the highest octane gasoline available octane minimum. Do not rely on the factory boost meter if equipped when adjusting the maximum boost pressure. Install an HKS auxiliary boost pressure meter to monitor manifold boost pressure levels. Mount the EVC control unit, display unit and harness away from high-power amplifiers, two-way radios, mobile phones, and their respective antenna cables to prevent malfunction of the EVC unit.

Disconnect the negative battery cable from the battery. EVC stepping motor installationDetermine an ideal mounting location for the stepping motor.

Mount the stepping motor to the chassis using the hardware provided with this kit. Do not install the stepping motor close to the exhaust manifold or any area of high temperature. Do not install the stepping motor where it will be exposed to water or moisture. Ports 1 B , 2 I , and 3 O must face upward. Lengths on all hoses must be kept as short as possible. Vacuum Filter InstallationInstall vacuum filters per diagram to the right.

Make sure the filters are within 10cm 3. The 6mm vacuum filter should be installed with the short side facing the stepping motor. Inspect the filters every miles. They must be clean for the EVC to function correctly. If the filter is contaminated or dirty, replace with a new 4mm RA or 6mm RA Do not attempt to clean the vacuum filter.

If the filters frequently need replacement, relocating the pressure source may solve the problem. Connect the red wire 2-pin harness from the EVC to a volt ignition source. Connect the black wire 2-pin harness from the EVC to a chassis ground. Make sure there is no paint or rust on the ground surface. If there is, sand the surface until bare metal is exposed.

Determine if the vehicle is equipped with an internal wastegate single port actuator , dual port actuator, or an external wastegate, then proceed to the corresponding installation instructions.

Do not connect port 1 to the line that operates the fuel pressure regulator unless the supplemental instructions tell you to do so. This hose should be as short as possible and should not exceed cm Install the 4mm vacuum filter within 10cm 3.

Port 2 I - Connect to a source of pressurized air such as a turbocharger compressor housing discharge side or compressor outlet pipe before the intercooler using the 6mm hose. Install the 6mm vacuum filter within 10cm 3. Port 3 O - Connect to the port on the wastegate actuator. Port 2 I - Connect to a source of pressurized air such as the turbocharger compressor housing discharge side or compressor outlet pipe before the intercooler using the 6mm hose.

Use the tee fitting supplied with this kit to connect a pressure line to the secondary port on the wastegate actuator. Both lines should be as short as possible and should not exceed cm Port 3 O - Connect to the port above the diaphragm on the wastegate actuator or wastegate.

There is no need to start the engine. Park the vehicle in a safe place when adjusting the EVC. Example: Mode A Note: As a safety feature, when the of the volume knob blinks, its acting as a lock for the previous boost setting. If a boost setting is attempted while the volume knob is blinking, it will not change the boost.

In order to adjust the boost level, turn the knob full clockwise and then full counter-clockwise. Log in Get Started. Download for free Report this document. Embed Size px x x x x Set the wastegate selection switch SW or PO. Refer to the diagram below: 5.

Turn the knob full counter-clockwise. Make sure the of volume knob B is red.
