We need your car's unique ECU ID to make sure the file we build is a perfect match.
To get it:
- Connect your EK1 to your car's OBD port.
- Turn the ignition ON, but don't start the engine.
- Power on your EK1, go to "1. Power Mode," then select "3. Read ECU ID."
- It's critical you select the correct protocol for your car from the list. If you're not sure, just ask us, but here's a small list of examples.
