(tldr) > So instead of one clear answer, we have three possibilities: 1957 Rambler, 1958 Chrysler or 1968 Volkswagen.

Early electronic fuel injection was pretty shit. https://en.wikipedia.org/wiki/Jetronic https://en.wikipedia.org/wiki/Jetronic No throttle control, cold start compensation with a bimetal strip + heater coil controlling extra air flap. Sensors were super primitive or omitted altogether (no temp sensors), air was measured with turbines restricting flow, no lambda, etc etc. Crazy Honda fact: all their ECUs from 1992 (P05) onward had full facility to drive individual coil on plug, but officially Honda switched away from mechanical distributor in 1999 (S2000?). You can trivially convert 92 car with a small adapter board, ECUs shipped with all the needed firmware and hardware in place sitting unused for 7 years.
