I'd strongly dispute that. Why not include the spark plugs as well? And the fuel pump? The ECU is a computer, a packaged bundle of chips which plugs in to wire

The ECU is a computer, a packaged bundle of chips which plugs in to wires and does nothing but communicate to other components via those wires. That's what an electronic control unit means.
The driven devices, amplifiers etc. are under the control of the control unit. They are not part of the control unit. They're located in areas subject to much more heat and mechanical stress, and in most cases (ignition coils excepted) are mechanical in function.
- phaedrus 7y agoI think GP is saying they're physically located on the ECU board / inside the ECU box, not that they're conceptually part of the ECU even if separate. Whether they are or not (physically inside the ECU box) differs by make and model.
