The Toyota MR2 Turbo SW20 is a beloved sports car known for its mid-engine layout and impressive performance. With the right tuning, it can achieve remarkable power gains, especially when paired with the AEM Engine Management System (EMS). This article will guide you through the tuning process to maximize your MR2 Turbo’s power to an impressive 400 horsepower.

Understanding the AEM EMS

The AEM EMS is a powerful tool for tuning your MR2 Turbo. It offers advanced features that allow you to control fuel, ignition timing, and boost levels with precision. By utilizing the AEM EMS, you can optimize your engine’s performance and achieve your horsepower goals.

Preparing for the Tune

Before diving into the tuning process, it’s essential to prepare your MR2 Turbo. Here are the key steps to take:

  • Ensure your engine is in good condition.
  • Upgrade your fuel system to support higher horsepower.
  • Install a high-performance intercooler.
  • Consider upgrading the turbocharger for better airflow.
  • Check the exhaust system for restrictions.

Installing the AEM EMS

Installing the AEM EMS is a crucial step in the tuning process. Follow these guidelines for a successful installation:

  • Disconnect the battery to prevent electrical shorts.
  • Remove the factory ECU from the vehicle.
  • Connect the AEM EMS harness to the engine’s wiring.
  • Secure the AEM EMS in a safe location within the engine bay.
  • Reconnect the battery and check for any wiring issues.

Tuning Process Overview

Once the AEM EMS is installed, it’s time to begin the tuning process. This involves adjusting various parameters to achieve optimal performance:

Fuel Tuning

Fuel tuning is critical for maximizing power. Adjust the following settings:

  • Set the fuel map for the desired air-fuel ratio.
  • Adjust the fuel pressure regulator if necessary.
  • Monitor the fuel trims for any inconsistencies.

Ignition Timing

Proper ignition timing is essential for performance. Follow these steps:

  • Adjust the ignition map for optimal timing based on RPM and load.
  • Use a timing light to verify actual timing against the map.
