FEMTO DME ECU Unlock Service

Unlock Your BMW's Potential with FEMTO DME ECU Unlock Service

Introducing the FEMTO DME Unlock service from Finland, essential for BMW and Toyota GR Supra vehicles produced after June 2020. These models require a FEMTO unlock before any flash-based tuning can be performed, as they cannot be bench unlocked in-house.

Key Benefits

• Unlock OBD Flash Tuning: Enables OBD-based flash tuning on platforms like bootmod3 (bm3), MHD Tuning, MG Flasher, and more.
• Comprehensive Service: Includes international shipping to and from MTech Performance, with your DME fully tested and inspected upon return.

Why Do You Need a FEMTO DME Unlock?

• Updated Bootloader Restrictions: BMWs after June 2020 block OBD tuning via traditional bench unlocks.
• Exclusive Solution: FEMTO is the only known working solution for unlocking post-2020 DMEs for tuning.

Unlock Process (Mail-In)

1. Purchase the Service: Order through our online store (includes shipping).
2. Prepare Your Vehicle: Activate BM3 or MHD before sending DME.
3. Ship the DME: Send it to MTech Performance in Fort Lauderdale.
4. Processing & Unlock: DME is shipped to FEMTO in Finland and returned within 7–15 days.
5. Reinstall & Flash: Reinstall DME, test vehicle, and flash your custom map.

Note for South Florida customers: We offer mobile DME removal for an additional fee. Contact us for a quote.

Important Considerations

• OTA Updates: Disable Over-The-Air updates in iDrive to avoid losing the tune.
• Tuning Licenses: BM3 sold separately.
• Remote Start: Optionally retained during unlock if selected (existing feature only).
• Shipping: DHL Express used for Europe delivery. 7–15 day turnaround (customs may vary).
• V8 Engines (e.g. N63TU/S63TU/S68): Require dual DME unlock. Select correct quantity and ship both units.
• Shipping Responsibility: MTech is not liable for improperly packed or damaged units.
• Business Address:
  MTech Performance
  5400 NW 10th Terrace
  Fort Lauderdale, FL 33309
