Time for the archives.

EHA current = the current flowing through the electro hydraulic actuator. EHA current is the mechanism of control.

You can not be in control and have the driving condition you describe. So looking at it is not necessarily going to tell you anything. Read in the archives about monitoring and adjusting the fuel control system. Monitoring it from the point of failure could indicate the problem.

In other words, the system must achieve control - closed loop! First step could be to establish control or find out why not. If control can be established at low load (idle say) then watching it as control is lost can indicate the problem.

But as I said originally I would monitor fuel pressure because if that is your problem you will have to be good to catch it through monitoring control.
