Preparation
Before starting, ensure your vehicle is parked on a flat surface and the engine is cool. Disconnect the negative terminal of the battery to prevent any electrical issues. Gather all tools and materials listed above.
Locating the Engine Control Module (ECM)
The ECM, also known as the ECU, is usually located under the hood, near the engine. Refer to your Toyota Sienna’s owner’s manual for the exact location. Once located, open the hood and locate the ECM connector.
Accessing the ECM

Installing the Performance Chip
Before installing, read the instructions provided with your performance chip. Typically, the chip is a plug-and-play device that connects directly to the ECM port.
Connect the chip to the ECM socket firmly. Ensure it clicks into place and is secure. Some chips may require additional configuration, so follow the manufacturer’s instructions carefully.
Final Steps
Once installed, replace any covers or panels you removed. Reconnect the negative terminal of the battery. Start your vehicle and check for any warning lights or issues. If everything runs smoothly, you’ve successfully installed your performance chip.
Testing and Optimization
Drive your Toyota Sienna and observe the performance changes. Some chips may require tuning or adjustments for optimal results. Refer to your chip’s manual for further calibration options.
