Unlock Your BMW’s Full Potential with FEMTO
If you own a BMW manufactured after June 2020, chances are you’ve run into roadblocks trying to tune it. That’s because newer BMWs come equipped with locked MG1 or MD1 ECUs, making traditional tuning impossible. That’s where FEMTO Unlock comes in — the gold standard solution for safely unlocking your BMW’s ECU and restoring full tuning access.
What is FEMTO Unlock?
FEMTO Unlock is a secure and proven service that allows you to unlock your MG1 or MD1 ECU to enable custom tuning, performance upgrades, and advanced diagnostics. This method is currently the only reliable way to unlock post-06/2020 BMW ECUs, and it works without compromising your car’s safety or factory settings.
Once your ECU is unlocked, you’ll have full access for OBD flashing, tuning with software like Bootmod3, MHD, or Ecutek, and the ability to modify maps for performance, fuel economy, or engine upgrades.
Compatible BMW Models
FEMTO Unlock supports most BMW models with MG1/MD1 ECUs built from June 2020 onward, including:
- G20/G22 3 and 4 Series (330i, M340i, 430i, M440i)
- G80 M3 / G82 M4
- G01 X3 / G02 X4 M40i models
- G05 X5 / G06 X6 / G07 X7
- And more
