Hint: automatic chokes between manual and ECM were fucking awful in cold weather, because they had poor edge case adaptation. They were better than manual at getting choke valve angle mostly right once you get the car actually started. Essentially, those are a really small analogue computer that switches the angle of the choke based on temperature return from a powered thermocouple. That's why they needed outside power to work, and needed tuning to work properly in the first place.
This is why everyone switched to ECMs asap. Even before fuel injection in higher end models. Fully computer controlled engine that functions off the multitude of sensors means your engine tunes itself all the time to the optimal running pattern.
Most people forget that engines used to only last somewhere around 100.000 km, and automatic transmissions even less. They were more simple, and as a result ate far more wear and tear. Cheaper to repair and replace, much less efficient, and far less durable.
No one sane wants them. Even in developing countries, they're avoided like the plague for most uses, because they just wear out. The longest lasting engines (other than that one hilariously overbuilt full analogue Volvo that still runs North Korean taxi fleets) are all the early ECM versions, because you had massive overbuilding of the old analogue engines coupled with very low wear and tear due to ECM optimization of the operation. Go to African shitholes, and you see tons of those old Toyotas, Hondas, Mazdas etc with early ECM engines still running fine clocking kilometer readings that is closer to a million than zero. But almost no engines before that time. Those are long dead no matter how hard you try to maintain them, because without ECM, wear and tear is horrible.
And that is why no one wants engines that aren't ECM controlled any more. Or anything else for that matter. Remember early automatic windows? Ever seen the wiring diagrams of those cars and why no one who wanted a maintenance nightmare wanted them?
