I designed a drop in replacement ignition ECU for Ferrari 308 cars from the 1980's (the Magnum PI model), as after almost 40 years a lot of them are now failing. When I started the project, I had no idea how miserable an environment the car actually was. It wasn't hard to get a prototype that basically worked, but I had to go through quite a few revisions before I got something that could withstand the torture of everyday use (and things like electrically dirty jump starters that would completely fry my units until I put a protective power supply in it against +/-100VDC surges.)
