Unless I'm completely wrong, the alternator is not controlled by the ecu. It has an internal voltage regulator in the alternator. Also, the voltage you reported at idle is too low, it should still be 13.5 volts. As engine speed changes the available current will change as well, however the voltage should remain constant if the wiring and alternator are both working properly.
