There are plenty of FOSS engine management projects around. There is a big community of people doing incredible mods. But cars are complicated and to do it well requires a lot of time, effort, knowledge, money. I've blown up plenty of engines along the way, and it's fun and I'm learning a lot, but it's not something that's easy to just dabble in.

Tesla is full of open source software, including the Linux kernel. They probably are GPL violators though.

See also this interesting slide deck about the GPLv3 and cars, I expect that regulations would mean you could not drive cars with modified software (similar to what happens with solar inverters):

Aggressive regulations for emissions control software + industry deterrence for car modifications via insurance and warranties

Good then that there is very little need for emissions control in EV. No barrier for giving the owner of the vehicle more access to its innards.

Not exactly what you are asking for, but did you see that Rivian recently provided a way for owners to disable the vehicle's LTE connection? It's straight In Canada. In the US, you have to ask a dealer.

If you can find a good security vulnerability Tesla will give you root on your car as an award.

If you found that vuln, wouldn't you already have root?
