No fuel injection or electronic ignition? I'm sure there's an ECU somewhere in the vehicle.

This is the sentiment completely.

My 34-year old base spec Chevrolet has digital controls for timing advance, fuel trim, and integrated Engine and Transmission Control Units. But my dash has some analog components ( fuel level is variable voltage instead of PWM ). The mechanics would all say that my truck is very simple, and "old school"

The Lay use of 'analog' is far removed from function. As long as there isn't a screen, it isn't seen to be digital. I studied photography in college and loved shooting film. I have a processing machine that is based on a 6502. When people would talk about non-digital things as analog it would bug me (One is chemical, and one is a computer).

  • The last real analog stuff would be either carb'd bikes / cars or mechanical fuel injection, which is the worst of both worlds.

    However, those ECUs are more closely related to embedded programming than digital dial outs and SIM Card loaded cars with a internal network canbus these days. Analog / Digital Inputs and outputs as a closed loop controller.
