Story time. I had one car about five years ago - a 1982 VW Scirocco. A 1.7L engine powered by mechanical fuel injection, controlled by an early ECU.

The ECU was mounted next to a hood hinge. Resoldering some connections for some capacitors fixed it. I ended up swapping in a modern turbo motor though. :)
