This is a thread for people to post links, images, etc related to taming CIS injection.

All I know are the basics, and please correct me if I have that wrong as well.

Kjet or CIS, Continuous Injection System is a mostly mechanical pressure controlled system. The injectors have no electrical control, flow depends on manifold vacuum on one side and fuel pressure as controlled by the fuel distributor, WUR, and fuel regulators on the other side.

Fuel pressure regulators adjust the "base" fuel pressure by controlling the amount of fuel from the tank and fuel pump that is returned to the fuel tank. They keep the base pressure a fixed amount above the manifold pressure.

WUR, warm up regulator sends a control pressure to the fuel distributor, and all I understand is that it makes the air fuel mix richer when the motor is cold.

Fuel distributor, combined with the air meter "vane" the flow of air into the motor moves an internal piston up and down and that controls the pressure of the fuel to each of the injectors.
