BMW MSD80.2 TO MSD81.2 cloning via flex bench or other tool

[Nik Matsa]

Hello,
I want to clone a bmw MSD80.2 to MSD81.2. Is it possible via flex? Did anyone tried something like that?
Both ecu files (bench full read) are same size, mcu is tc1796 for both ecus.
I would try to copy, but I want to eliminate the risk of bricking spare ECM

you CAN NOT clone from 80.2 to 81.2 unless you do more steps, search google plenty of info there
