The ignition timing is set by the electronic ignition timing control system. The initial data is processed by the engine control unit (ECM).
Note: It should be noted that in diagnostic systems such as those used on fuel-injected engines, when the battery is disconnected, all information stored in the computer will be erased. Therefore, before disconnecting the battery, remove all diatonic information from the computer.
Engine parameters (rotation speed, temperature, etc.) are determined using various sensors.
