Octavio,

You say that you wish to know the strategy for control of "actuators, EHA, injectors, idle valve, coil etc, etc.

One of us has a big misunderstanding. I thought we were talking KE. There is ONLY EHA and IDLE VALVE control in that controller, no coils, no injectors, no actuators, just EHA current. Tell me whats wrong with your EHA current? It uses pulse width controled current flow to the idle valve. What is its current? At idle? w/AC? off idle? In gear?

I don't want to be hard but you are asking technical questions beyond my knowledge and beyond the need of a diagnosis. The questions I ask are those I see as necessary to decide whether the controller is the problem (a very rare occurance).
