ECU / DME OBD Unlock

BMW ECU/DME OBDII Bench Unlock (Including Toyota Supra MKV)

Unlock the Full Potential of Your BMW

Many F-Series and G-Series BMW models come with a factory-locked Bosch ECU/DME, preventing tuning modifications via the OBDII port. This affects most models with BMW software updated after March 2019, including:

M140i, M340i, M2 , M3, M4, M5, M8, and more

How It Works

To enable OBDII tuning capabilities, your ECU/DME must be reprogrammed with a one-time patch that:
Allows OBDII tuning and reprogramming
Is completely safe and does not alter factory performance

Important Note

Bosch ECUs with build dates of June 2020 or newer cannot be unlocked at this time.
👉 The ECU build date (not vehicle build date) is found on the ECU label itself.
