I need a computer box from any car

I'm a student in electronics and I would like to see a car computer box for fuel injection, etc. So I can have my first contact to it and see what I need to fix it. Any car will do, but as I have a Mirage 98 model, I prefer that one so I can look it in my car in detail. In my Mirage, I don't know what that is.
I want to see if I can learn to fix computer box from cars.
Thank you
