Hey guys, sorry if this has already been covered, I’ve tried searching but can’t really find anything specific about this question. I have a 21 m340 and been considering getting it tuned. I know my DME would need to go off to FEMTO for an unlock, but I’ve got a line on some DMEs out of some 2020 vehicles that should all be pre 06/2020. I really like the idea of buying one of these, doing a bench unlock and having my tune on that instead of my factory DME. Only issue is the DMEs in question come out of either an A90 Supra or X3 M40i. Would there be issues running these in my car if they were flashed with the appropriate map for what I want to run?

Could you email Femto and see if they're still doing DME cloning? I'm not sure, but I saw a guy on YouTube saying they stopped doing it.

What is your goal?
Having a DME that you can unlock over and over again with a tool like the MHD bench unlocker?
Reach out to FEMto and ask him about the cloning service.
If your goal is warranty, don´t even try it as BMW can see this.

The goal would be to leave my factory DME alone and have the donor tuned. If the car required a service that would have it plugged in and potentially flagged, I could swap my factory DME in and avoid that. If BMW could tell my cars DME was cloned, it's a moot point.

I have thought of this but I read something that the odometer on the dash is going to be different than the locked ecu you swap in after. I don't think it will work
