How to Find Your ETK VCI Adapter ID
Use this guide when purchasing a remote tune license for an ETK VCI you already own.
- Open the ECU Tool Kit (ETK) application.
- Select the About tab at the top of the window.
- Find License in the information row below the tabs. The number beside License is the adapter ID to enter on the tune product page.

Check the ID before ordering
The adapter ID must contain exactly nine digits, begin with 5502, and contain no letters, spaces, or hyphens. If the License value is missing, contact 550Performance before placing your order.
