Morphology

ECU = E + C + U

ECU is an initialism (Engine/Electronic Control Unit); the individual letters are not productive English morphemes, so the meaning cannot be derived from the parts.

Etymology

ECU in cars comes from the first letters of Electronic Control Unit, a simple name for the small computer that controls the engine and other parts. So an ECU works like the car's 'brain', making decisions about fuel and emissions.
