D-Jet was analog electronic. Yes it had an ECU.

K-Jet is mechanical because fuel pressure opens the injectors. There is no ECU.

Only K-Jet cars with the Lambda Sond system had the frequency valve that Phil mentioned. Also this is where the oxygen sensor originated. This is an emissions control system and it has a control unit. But it monitors the fuel/air mixture. It does not control the fuel injection.

Early K-jet cars did not have the Lambda Sond system.
