Preparation Steps
Before starting the installation, ensure your work area is clean and organized. Gather all necessary tools and components. Disconnect the battery to prevent any electrical shorts during the process.
Remove the Stock ECU
Locate the stock ECU in your Acura NSX. It is typically found under the dashboard on the driver’s side. Use your screwdriver to remove any screws or clips securing the ECU in place.
Once loose, carefully disconnect the wiring harness and remove the ECU from its mounting location. Store the stock ECU in a safe place for future reference.
Install the Motec M150 ECU
Now, take the Motec M150 ECU and position it in the same location as the stock ECU. Secure it using the screws or clips you removed earlier. Make sure it is firmly in place to avoid any movement while driving.
Wiring Connections
Refer to the Motec wiring diagram provided in the kit. This diagram is crucial for correctly connecting the ECU to your vehicle’s sensors and power supply.
Power Supply Connection
Identify the power supply wires in the wiring harness. Use your wire cutters and strippers to prepare the ends of the wires. Connect the power wires to the corresponding terminals on the Motec M150 ECU.
Sensor Connections
Connect the various sensors to the Motec ECU as per the wiring diagram. This includes the throttle position sensor, camshaft position sensor, and others. Ensure each connection is secure and insulated with heat shrink tubing or electrical tape.
Finalizing the Installation
After all connections have been made, double-check each one for accuracy. Use a multimeter to verify that there are no shorts or incorrect connections. Once satisfied, reconnect the battery.
Configuring the Motec M150 ECU
With the physical installation complete, it is time to configure the ECU. Connect your diagnostic laptop to the Motec M150 using the provided USB cable. Launch the Motec software to begin the configuration process.
Loading Base Maps
Select a suitable base map for your Acura NSX from the Motec software. This base map will serve as a starting point for tuning. Load the map onto the ECU and save your settings.
Tuning the ECU
Once the base map is loaded, you can begin tuning the ECU parameters to optimize performance. Adjust fuel maps, ignition timing, and other settings based on your specific performance goals.
Testing Your Installation
After completing the tuning process, it is essential to test your installation. Start the engine and monitor the performance metrics using the Motec software. Look for any error codes or issues that may arise during operation.
Conclusion
Installing the Motec M150 ECU on your Acura NSX can unlock significant horsepower and improve overall performance. By following this guide, you can ensure a successful installation and enjoy the enhanced capabilities of your vehicle.
