Thats not true for all Motronic ECUs. The OEM has to decide which kind of tuning protection they want to have activated. Some OEMs opt for the low settings where tuning gets detected and logged while still allowing you to run new or modified code while others only allow the flashing of signed code. Also, as far as i know from motronic mods, they mostly only change calibration data and not the code itself, but i may be wrong.
