FEMTO DME Unlock Service (Post-06/2020 BMW & Toyota Supra)

Unleash the true potential of your B58 or S58 engine.

If your BMW G-Series or 2021+ Toyota GR Supra was manufactured after June 2020, your factory engine control unit (DME) is locked by Bosch, preventing you from flashing aftermarket tunes via the OBD2 port.

The FEMTO DME Unlock is the industry’s only proven solution to bypass this lock. By sending your DME to us, we facilitate the specialized FEMTO unlocking process so you can finally run industry-leading software like bootmod3, MHD, or custom ROMs. Stop leaving horsepower on the table and get the tune your car deserves.
