- Your ECU must NOT be locked by a previous tuner/tuning system such as ECUtek, MazdaEdit, BRZEdit, or any other potential tuning suite available for your vehicle. If your ECU is locked you will most likely experience a OFTCODE 10003 while trying to read.
- If you believe your ECU is locked, please contact us using the form on our site for information about how to proceed next.
- OFT must be NEW (or previously uninstalled from any other vehicle). An OFT that is installed on another vehicle/ECU will NOT have the read option available within the TUNING menu
- Be sure your Key/Ignition is in the ON position.
- Not accessory, or OFF.
