I am a software engineer. I like to remove speed limit of my M3.
I can buy another BMW ECU to flash it and keep the original ECU for service only.
Problem is:
Electronic devices are running concurrently and data store in different NVRAM modules.
Once there is a problem, I can reinstall my original ECU, how can I flash all the rest NVRAM for a reset?
You cannot disconnect power to flash NVRAM.
If I don't flash it all, BMW will know. I don't know what to do rather than leave it.
