Locking To/Unlocking From An ECU

Upon connecting to an ECU with an unregistered KTuner unit you will be asked to add the unit to the system. You must be on the internet to register the unit and also lock the unit to the ECU. Once you’ve registered the KTuner unit it will then prompt you to lock to the ECU. Please read the information carefully before you agree and proceed.
This can be unlocked in the event you are going to sell your KTuner unit by reverting to stock and going through the unlock process.
You must return to factory. After returning to factory the unlock option will be available. As of upon connecting to a factory tuned vehicle the unlock option may be availble for 30 seconds if the ECU software is currently supported by KTuner.
Internet connectivity is required to unlock. You need to be connected to the vehicle with the key in accessory mode.
Verifying It's Unlocked
You can check if your unit is locked and provide a buyer with an image of this by going to Reflash Info in the Tools menu and referring to the KTuner Units tab.
