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.
