With the steady EHA current you're seeing, it can't do anything useful. I would suggest, for now, just make the manual adjustment using the main mixture hex-head screw and set it so that the output of your O2 sensor averages around .45 volts. That's what I did and at least the car is now drive-able until I can swap the ECU.

My wife took the car this morning and said it has stalled every time she lets off the gas pedal.
