Can any of this be done using an open source design? that is, would it be possible to create open source engine management kits for vehicles?

There's also a fair amount of open source short of full engine management. Things like read/write into the CAN bus, altering fuel curves without fully taking over the engine computer, burning altered EEPROMs for older ECMs, etc.

Thank you! Would you know why it is not possible for the entire engine management unit to be fully open sourced?

Yes, yes, and that's already been done:

and others...

Thank you!

AFAIK you can "just" take Cortex-R based MCU and just configure it properly and you will get the "resets if 2 cores don't agree" behaviour
