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.

ECUs talked to each other over a digital bus long before anyone added a connection to the internet.

The first 20yr of automotive computers they weren't really talking to each other and when they were it wasn't really bidirectional and it wasn't typically on a bus unless you wanna call a dedicated wire a bus.

I was working on diagnostics for cars using CAN in 1995.

If you were dealing with CAN back then then you of all people know it wasn't the norm at the time.

		That was after the first 20 years of automotive computers, though, wasn't it, if only barely? WP says, "In the early 1970s, the Japanese electronics industry began producing integrated circuits and microcontrollers used for controlling engines.[6] The Ford EEC (Electronic Engine Control) system, which used the Toshiba TLCS-12 microprocessor, entered mass production in 1975.[7]" Reference [6] says, "First half of 1970s: Japan starts developing ICs for automobiles ahead of the U.S.: Development of ICs for automobiles started with analog ICs for in-car entertainment, and was followed by 4-bit microcontrollers and other digital ICs for use with the wipers, electronic locks, and dashboard, and then by microcontrollers with 8-bit and wider bits for engine control." But I don't know any more details. Was Toyota controlling its windshield wipers with a 4004 in 01974? Was Nissan controlling a speedometer with an RCA 1801 in 01973? Anyway, if we date it from 01975, then 01995 would be year #21.
