Using your laptop or tablet, connect to the Cobb Tuning ECU via the OBD-II connector. Download the necessary software updates from the Cobb Tuning website. Follow the on-screen instructions to complete the update process, ensuring that your ECU is running the latest firmware.
Step 7: Testing the Installation
Once the update is complete, start your vehicle and let it idle for a few minutes. Check for any warning lights on the dashboard. If everything appears normal, take your E63 for a test drive to experience the performance gains firsthand.
