An ECU/EMM failure can not cause excessive oil consumption. The most likely causes of excessive oil use are - Oil lift pump failure, restriction (pinching) of the oil return line, oil injector failure.
Your usage cycle could also be a contributing factor. When the engine coolant temperature is below normal temperature, as the engine is accelerated above 2500 RPM, the oiling system delivers multiple injection shots. If this operational cycle is continually repeated, excessive oiling could be observed.
