  • Wire strippers and connectors
  • Electrical tape
  • Vacuum hose (if not included)
  • Mounting hardware
  • Vehicle manual for reference

Preparation Steps

Before beginning the installation, it is essential to prepare your workspace and gather all necessary tools and materials. Make sure your vehicle is parked on a flat surface and the engine is cool. Disconnect the battery to prevent any electrical issues during installation.

Installing the Greddy Profec B Spec 2

Step 1: Mounting the Controller

Choose a suitable location for the Greddy Profec B Spec 2 controller. It should be easily accessible for adjustments but out of the way of moving parts. Common locations include the dashboard or center console. Use the provided mounting hardware to secure the unit in place.

Step 2: Connecting the Wiring Harness

Connect the wiring harness from the Greddy Profec B Spec 2 to the vehicle’s electrical system. Follow the wiring diagram provided in the installation manual. Ensure all connections are secure and insulated with electrical tape to prevent short circuits.

Step 4: Connecting the Solenoid

The Greddy Profec B Spec 2 includes a solenoid that controls the boost pressure. Connect the solenoid to the boost source line and the wastegate actuator. Follow the diagram in the manual to ensure proper installation. Double-check all connections for leaks.

Step 5: Reconnecting the Battery

Once all connections are made, reconnect the battery. Turn on the ignition without starting the engine to check if the Greddy Profec B Spec 2 powers up correctly. Ensure all lights and displays function as intended.

Tuning Your Boost Controller

After installation, it’s time to tune your boost controller. This step is crucial for optimizing your vehicle’s performance. Start by following these guidelines:

  • Set a base boost level according to your engine’s specifications.
  • Gradually increase boost levels while monitoring engine performance.
  • Use a wideband air-fuel ratio gauge to ensure optimal tuning.
  • Adjust the settings based on driving conditions and performance goals.

Testing and Final Adjustments

Once you have completed the tuning process, it’s time to take your Eclipse GSX for a test drive. Monitor the vehicle’s performance closely. Pay attention to boost levels, engine response, and overall driving experience. Make any necessary adjustments to the boost controller settings to achieve the desired performance.

Conclusion

The installation of the Greddy Profec B Spec 2 boost controller can significantly enhance the performance of your Mitsubishi Eclipse GSX. By following the steps outlined in this article, you can ensure a successful installation and tuning process.
