2020 ECU on a 2021
Found a guy selling his 2020 m340i ECU. Curious if it would make sense and work if I bought it and swapped it into my 2021 m340i xDrive since the DME is unlocked and I wouldn’t have to worry about unlocking it to tune.
If anybody has and experience or knowledge to share that would be helpful. Don’t know too much about ECU’s and swapping but curious if it would work or if anyone’s tried it and it hasn’t worked. |

Doesn´t work as the ECU from 2020 have a different mileage and VIN.
And you can´t clone your 2021 ECU to the 2020 ECU without FEMto.

One other thing to consider is if the 2020 would work with your MH system(?)

That is good to know. So I could hypothetically send over my DME and the one from the pre-June 2020 to Femto and they can clone it for me allowing for me to never have to worry about this issue again?
