	Engine Control Unit - Wikipedia, the free encyclopedia
		If the ECU detects knock, a condition which is potentially destructive to engines, it can delay (retard) the timing of the spark to prevent this.
		The engine tuner can adjust this by bringing up a spreadsheet like page on the laptop where each cell represents an intersection between a specific RPM value and a gas pedal position (or the throttle position, as it is called).
		Gear control : Tells the ECU to cut ignition during (sequential gearbox) upshifts or blip the throttle during downshifts.

	Engine control system with motorized butterfly body - Patent 5482019
		An engine control unit, which is connected to sensors for detecting engine operation parameters and to the accelerator pedal, generates injection and ignition commands as well as a reference position of the butterfly, which is transmitted by a connecting line to the butterfly control unit.
		In the engine control unit 15, formulation of the signal about the reconstructed angular position of the butterfly is provided for mainly on the basis of signals about the air pressure in the intake manifold and about the engine speed, which the unit 15 receives from the corresponding sensors.
		The incorporated unit 1, associating with the motorized butterfly body 2 the electronic control unit 3 of the butterfly, is thus such that the motorized butterfly body 2 behaves as an intelligent actuator as regards the engine control unit 15, with which the control unit 3 of the butterfly is in a master-slave relationship.

	4x4Wire - Tech: Understanding OBDII Engine Systems and Fuel Mixture Control
		When the Check Engine Light comes on due to the fuel mixture related error codes P0171 and P0172, or your 3rd generation Toyota with either the 3.4L V-6 or 2.7L 4 cylinder engine is just not running like it should, the oxygen sensor and the Mass Air Flow Sensor (MAF) are common suspect items.
		The throttle position and engine load percentages shown in the first photograph need some explanation since the 29% engine load percentage, as reported by the scanner, seems a bit high for a vehicle sitting at idle.
		The fourth item, the "engine coolant temperature sensor" could be checked by comparing engine temperature readings seen in the OBDII data, and the instrument panel temperature gauge or using a thermometer to measure the water temperature returning from the engine to the radiator.
