Setting Up the AEM EMS
The AEM Engine Management System (EMS) is a powerful tool for tuning the SR20DET. It allows for precise control over fuel delivery, ignition timing, and other critical parameters to optimize performance.
Key Features of AEM EMS
- Wideband O2 control for accurate air-fuel ratio
- Customizable ignition and fuel maps
- Data logging capabilities for tuning analysis
Tuning for Maximum Power
Once the Bosch 440cc injectors and AEM EMS are installed, the next step is tuning the engine to reach the desired power output of 400 horsepower. This process involves adjusting various parameters to ensure optimal performance.
Essential Tuning Steps
- Set the base fuel pressure
- Calibrate the injectors in the AEM EMS
- Adjust ignition timing for optimal performance
- Monitor air-fuel ratios during tuning
Testing and Validation
After tuning, it’s essential to test the vehicle to validate the power output and ensure reliability. This can be done on a dynamometer to measure horsepower and torque accurately.
What to Look for During Testing
- Consistent power delivery across the RPM range
- No signs of knocking or detonation
- Stable air-fuel ratios
Conclusion
Tuning the SR20DET with Bosch 440cc injectors and AEM EMS can unlock significant power potential, allowing enthusiasts to reach their performance goals. With careful tuning and testing, achieving 400 horsepower is within reach.
