Pre-Installation Checklist
- Consult Your Manual: Refer to your Mitsubishi Lancer Evo’s service manual and the boost controller’s installation guide.
- Gather Tools and Materials: Ensure you have all necessary tools, wiring, and connectors.
- Prepare Your Workspace: Choose a clean, well-lit area with minimal distractions.
Connecting the Boost Controller
- Locate the Turbocharger Actuator:
- This is usually found on the turbocharger itself. Consult your manual for specific locations.
- Disconnect the Stock Actuator:
- Carefully disconnect the electrical and pneumatic connections from the stock actuator.
- Install the New Actuator:
- Connect the new actuator to the turbocharger, ensuring all connections are secure.
- Wire the Boost Controller:
- Connect the boost controller to the actuator and your car’s ECU if applicable. Follow the manufacturer’s wiring diagram.
### Wiring Connections Example
- **Boost Controller to Actuator**:
- Connect the pneumatic hose from the boost controller to the actuator.
- Connect the electrical wires according to the manufacturer’s instructions.
- **Boost Controller to ECU**:
- If your boost controller integrates with your ECU, connect the necessary wires.
- Ensure all connections are secure and insulated to prevent damage.
Setting Up Your Boost Controller
- Power Up Your System:
- Start your engine and let it warm up to ensure all systems are operational.
- Configure Your Settings:
- Use the manufacturer’s software or interface to set your desired boost pressure levels.
- Adjust settings for different RPM ranges and driving conditions.
Tuning Your Engine for Optimal Performance
Tuning your engine is crucial after installing a boost controller to ensure everything works in harmony.
Understanding Your ECU
- Factory ECU:
- The factory ECU has pre-programmed settings that may not be optimized for your new boost controller.
- Tuning Software:
- Use software like Tuner Studio or similar tools to adjust fuel injection, ignition timing, and other parameters.
Key Tuning Parameters
- Fuel Injection:
- Adjust fuel pump settings to ensure adequate fuel supply under increased boost pressure.
- Monitor fuel economy and adjust as necessary.
- Ignition Timing:
- Advance or retard ignition timing based on boost pressure to prevent engine knock or pinging.
- Rev Limit:
- Adjust the rev limit to protect your engine from over-revving under high boost conditions.
### Tuning Parameters Checklist
- **Fuel Pump Settings**:
- Ensure the fuel pump can supply enough fuel at high boost pressures.
- Monitor fuel pressure and adjust the fuel pump duty cycle if necessary.
- **Ignition Timing**:
- Advance ignition timing at lower boost pressures.
- Retard ignition timing at higher boost pressures to prevent engine knock.
- **Rev Limit**:
- Set a safe rev limit to protect your engine from over-revving.
- Adjust based on your driving style and the conditions you're in.
Common Issues and Troubleshooting
Even with a well-planned installation, issues can arise. Here are some common problems and how to troubleshoot them:
Over-Boosting
- Symptoms: Engine knock, reduced power, or warning lights on the dashboard.
- Solution: Check the boost controller settings and adjust them to prevent over-boosting. Ensure the actuator is properly connected and functioning.
Under-Boosting
- Symptoms: Reduced power output, poor engine performance.
- Solution: Check the boost controller settings and adjust them to increase boost pressure. Ensure there are no leaks in the pneumatic system.
Electrical Issues
- Symptoms: Erratic boost pressure, warning lights on the dashboard.
- Solution: Check all electrical connections for security and insulation. Use a multimeter to diagnose any wiring issues.
