Important ECU Unlock Information

Some BMW vehicles—especially models produced after June 2020—may require a bench or FEMTO ECU unlock before bootmod3 can be installed. The bootmod3 license does not include the ECU unlock, Wi-Fi adapter, ENET cable, or custom tuning unless specifically selected.

Please contact us with your VIN, model, production year, and engine if you are unsure about compatibility or unlock requirements.

This is a digital software license. Once the license has been activated or assigned to a vehicle, it is non-returnable and non-refundable.
