devRant.. I need your help.

So for the last year I've been self teaching myself python, go, & haskell. I've really been enjoying myself, to the point we're I would like to make it my career. Insert problem, I stumbled upon ECU(engine control unit) reprogramming & flashing, and instantly fell in love with the idea. However I can not find any information it. Every college I've called talks to me like I just asked them to teach me witchcraft.

Does any dev have experience with ecu programming? How did you get into it?

Thanks!
