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
👉 The ECU build date (not vehicle build date) is found on the ECU label itself.
