Eli se on moottorin ohjausyksikkö?
EDIT:

Wikipedia kirjoitti:In automotive electronics, an electronic control unit (ECU), also called a control unit or control module, is an embedded system that controls one or more of the electrical subsystems in a vehicle. Some modern cars have up to 70 ECUs, including:
* Engine Control Unit
o also called Powertrain Control Module (PCM)
* Transmission Control Unit - TCU
* Telephone Control Unit - TCU
* Man Machine Interface - MMI
* Door Control unit
* Seat Control Unit
* Climate Control Unit
Managing the increasing complexity of ECUs and number of ECUs in a vehicle has become a key challenge for OEMs.
