It depends a lot on the car and the engine.

If you want a high-performance engine that meets modern emissions requirements, you're probably going to be looking at EFI and turbochargers. Changing the fuel injection maps on a modern car requires something akin to rooting/flashing an Android.

It's also federally illegal, I don't know why you've veered this thread into ease of performing illegal modifications.

Not everyone lives in your jurisdiction. I don’t know why you would be quick to police the discussion, as talking about how something works is done does not mean you intend to do it (and is well within the scope of “Hacker” News).

Incidentally, rooting an android tablet is federally illegal too.

Are you referring to the DMCA?

The closest analog with smartphones to federal emissions laws is more like the FCC prohibiting hacking the baseband ostensibly to protect the cellular network.

EFI is pretty much all upside though. When things do go wrong, the engine just tells you what the problem is.
