DME Unlock service provided by Femto in Finland. All BMW vehicles with a production date after 07/2020 require the Femto unlock for flash-based tuning. At this time, this cannot be Bench unlocked in-house.
Once your MDG1 Series DME is unlocked, this enables OBD based tuning. This is required beforehand for such platforms as Bootmod3, and MHD Tuning through the OBD2 Port.
Starting July 2020 and onward, all BMW DMEs produced were shipped with an updated bootloader that rendered OBD Flash Tuning using existing protocols impossible. For a short time, there was no solution for this problem. Currently, as the community still anxiously waits for a US-Based DME Unlock for MDG1 DMEs, there is a solution available. The company known as Femto offers a mail-in service now known as the Femto Unlock. This unlocks your DME, making OBD Flash Programming possible.
Unlocking Process Outline
- Purchase the Unlock procedure from this page. With purchase, you’re also purchasing your Return Shipping Label.
- For those planning on running Bootmod3, you must create an account and activate your vehicle prior to removing your DME
- Remove your DME from your vehicle
- Mail your DME to our facility for preparation
- Typical wait time is 5-7 days (sometimes sooner) in which your DME will be unlocked and returned to you
- Reinstall DME in your vehicle, remember to turn off OTA updates
- Flash with your preferred Flash Tune
In the meantime your DME will be shipped via DHL to Femto/Finland, where it will be unlocked and returned to our facility in Anaheim, CA. In most cases with standard shipping this is about ~5-7 business day turnaround, sometimes sooner in some cases. Additionally, as an added safeguard - we add Apple AirTag tracking devices to each DME shipment prior to shipping.
Looking those for a DME Unlock for a vehicle produced Pre-07/2020, we can Bench Unlock in-house.
Please Note Charge is per DME, meaning V8 Customers will be subject to two Unlock charges. Simply ship your DME/ECU to our Anaheim facility and we will prep/ship your DME to Finland for unlocking and return it to you, ready for tuning.
DME Cloning
User must provide their own DME if cloning is desired, along with their current DME. Processing includes where applicable: 1:1 copy of the original excluding the OTP (oneTimeProgram) area, transfer of VIN, mileage, working hours, injection coding, ISN (Individual Serial Number for EWS2, EWS3 also EGS), SK (Secret Key, for EWS4, CAS2, CAS3, CAS3+, CAS4, CAS4+, FEM), programmed to vehicle’s current I-Level, coding and adaptation reset.
Note: BM3 License & VIN must be activated before sending us your DME. BM3 CustomROM will not be able to load if your license is not activated and VIN of your car is not in the BM3 user database. OTA Updates must be disabled in iDrive to prevent accidental tune removal, in which an Unlock process will be required again.
