Installing the Hks Evc Iv Boost Controller: Step-by-step for a 650 Hp Toyota Supra

The HKS EVC IV Boost Controller is a highly regarded device that allows drivers to control the boost pressure in their turbocharged engines. For those looking to enhance the performance of a 650 HP Toyota Supra, installing this boost controller can lead to improved throttle response and overall power delivery. Below is a step-by-step guide on how to install the HKS EVC IV Boost Controller in your Toyota Supra.

Tools and Materials Needed

  • HKS EVC IV Boost Controller Kit
  • Socket set
  • Wrenches
  • Wire strippers and connectors
  • Electrical tape
  • Vacuum hose
  • Zip ties
  • Multimeter

Preparation Steps

Before starting the installation, ensure that you have all the necessary tools and materials ready. It’s also crucial to work in a well-ventilated area and allow the engine to cool down completely to avoid burns.

Step 1: Disconnect the Battery

The first step in the installation process is to disconnect the battery. This is important to prevent any electrical shorts or issues while you are working on the vehicle.

Step 2: Locate the Boost Source

Next, you need to locate the boost source on your Toyota Supra. This is typically found on the intake manifold or near the turbocharger. Ensure that you have access to this area as you will need to connect a vacuum line from the boost source to the HKS EVC IV unit.

Step 3: Install the EVC IV Unit

Find a suitable location to mount the HKS EVC IV unit inside the cabin. Common locations include the dashboard or center console. Use the provided mounting brackets and screws to secure the unit in place.

Step 4: Connect the Vacuum Hose

Using the vacuum hose, connect one end to the boost source and the other end to the EVC IV unit. Ensure that the connections are tight to prevent any leaks that could affect boost readings.

Step 5: Wiring the EVC IV

Refer to the wiring diagram provided in the HKS EVC IV manual. Connect the power and ground wires to the appropriate locations in the vehicle. Use the wire strippers to prepare the wires, and secure the connections with electrical tape or connectors.

Step 6: Connect the Boost Control Solenoid

The HKS EVC IV comes with a boost control solenoid. Connect the solenoid to the EVC IV unit and route the lines to the wastegate actuator. This will allow the EVC IV to control the boost levels effectively.

Step 7: Reconnect the Battery

Once all connections are made, it’s time to reconnect the battery. Ensure that all tools and materials are cleared from the engine bay before doing so.

Step 8: Testing the System

Start the engine and let it idle. Check for any leaks around the vacuum hose connections and ensure that the EVC IV unit powers on. Use a multimeter to verify that the unit is receiving power correctly.

Step 9: Calibration of the EVC IV

Follow the instructions in the manual to calibrate the HKS EVC IV. This typically involves setting the desired boost levels and ensuring that the system responds correctly to changes in throttle input.

Step 10: Final Checks

After calibration, perform a final inspection of all connections and ensure everything is secured properly. Take the vehicle for a test drive to evaluate the performance of the boost controller and make any necessary adjustments.

Conclusion

Installing the HKS EVC IV Boost Controller in a 650 HP Toyota Supra can significantly enhance your driving experience. By following these steps carefully, you can ensure a successful installation that maximizes your vehicle’s performance. Always remember to consult with a professional if you encounter any issues during the installation process.
