Most modern EFI systems are incorporated in an ECU which also controls the ignition system, and may control may other functions such as anti-lock brakes, traction control systems, the transmission, etc. A fuel injection system itself consists of a source of pressurized fuel, fuel injectors and the electronic controller. The fuel system is composed of the fuel tank, a high pressure pump, and some method for regulating fuel pressure. The injectors can be though of as electrically operated valves. The amount of fuel delivered to the engine is determined by size of the injectors, the amount of time that the injectors are open, and on the fuel pressure. The electronic controller to determines how much fuel is needed and commands the injectors to remain open for the necessary amount of time to deliver the needed fuel volume. The amount of time that the injector is open is called the pulse width and is usually expressed in milliseconds (one thousands of a second). A simple EFI system can operate fairly effective with just these three inputs. However, many systems include additional inputs from the following types of sensors. Most sensors are of one of two types. Some are simple on-off switches or counters, such as a gear indicator or tachometer. Most measure continuous variables like temperature or airflow. These sensors produce a 0-5v output. This signal is read by the ECU (computer). By referring to a calibration table, the ECU translates the signal into a value representing the physical parameter which is being measured, such as airflow in units of mass/time or temperature. The tuning process boils down in most cases to changing the values in these tables.
