Will anything change?
• If using an ECU other than factory the immobilizer light on the dashboard will flash. You can disable the immobilizer in the software and unplug the immobilizer unit to prevent flashing on the dashboard or you can have the ECU sync’d to your immobilizer at any Honda/Acura dealer. *If you have already locked your KTuner unit to the ECU unlock it before they sync the immobilizer or tell them not to change the ECU VIN number. If they change the VIN number the KTuner unit will no longer communicate with the ECU if it’s locked to the previous VIN already.*
