Congrats, you presented the one and only case where the manufacturers are right: Nobody should tamper with critical control systems.
I don't want a DIY arduino-hacked suspension control chip or ABS. Neither would your clients. Unless of course your client understands this and it goes into the service logbook and you take full legal responsibility for any accidents this might cause in the future.
However I couldn't care less if my mp3 player has it's EMMC swapped or if my laptop has a third-party LCD replacement.
