How to Flash Your ECU?

• We can bench flash the ECU. To bench flash the ECU, you must remove it from your vehicle and send it to us. Once we receive the ECU, we will prepare the tune file and then ship it back to you for reinstallation. We do not open, solder, or modify the ECU board at all. Connections are done directly to the pins on the front of ECU.
