Furthermore, an ECU comprises a computer that uses a microchip to process the inputs from various engine sensors in real-time. The engine control systems aren't really designed by the auto manufacturer -- they're one of the components that's sourced and then customized. Incorporating many features into one unit capable of coordinating and orchestrating everything makes the initial cost of entry higher, but also reduces the need to buy and install additional electronics—making the tuning process even easier. It is designed to detect almost any problem that can cause emissions to exceed the federal limit by 1.5 times. Similar management systems are used in the management of other critical areas such as quality, occupational safety and health, security, environment, etc. 3. Additionally, since some reflash systems allow the factory fuel and ignition timing maps downloaded to be used as baseline maps the possibility of post-tune drivability issues diminishes. If there's a problem, the sensor will tell the engine control unit (ECU) which will turn on the engine management light. This system is also widely referred to as an ‘Electronic Engine Management System’ or the EMS. While this installation is more involved, it offers a chance to connect the stand-alone ECU necessary components only. Flashing engine management light (amber) ECU 101: Engine Management Systems Explained. If the ECU has control over the fuel lines, then it is referred to as an electronic engine management system (EEMS). ROM tuning provides a similar function; it allows a tuner to alter the maps in the ECU to optimize spark and fuel delivery for maximum power. Some units allow factory fuel and timing maps to be saved for future “down converting” allowing the enthusiast to re-flash the factory ECU with the original default maps, if necessary. They offer engine management systems for both EFI and carbureted engines (carbureted LS engines are available from Chevrolet Performance as crate or carb-converted Gen III/IV engines).

Only a handful of OEMs (original equipment manufacturers) make ECM systems for cars. Additionally, some modern factory ECUs are adaptive, meaning the factory fuel and ignition maps are constantly readjusting to stay within factory parameters. There are 2 types of the crankshaft position sensors. Additionally, some reflash units offer add-on features that facilitate control of other computer controlled systems on the vehicle, making the unit a more viable solution for complete engine and vehicle management. Generally, stand-alone engine-management systems offer higher-resolution fuel and ignition maps for tuning. This is an advisory warning, which indicates an engine issue that affects emissions. Since piggyback systems intercept and correct the signals going to the injectors and coils based on a fixed map, the tune may become altered over time. Hartman's book provides comprehensive information about the various components of engine management systems, from sensors and actuators to the computer systems that make everything work. The possibilities are almost endless. Furthermore, the Engine Management system is incorporated in the modern-day engine technologies. These arrays are in turn combined with other arrays containing parameters for specific conditions as read by a number of other sensors present on the engine. The printed circuit board (PCB) of the ECU consists of a micro-controller chip or the CPU (Central Processing Unit). Modern Engine Management Systems (EMS) use an oxygen sensor in the exhaust to monitor the air to fuel ratio (AFR). The Intel Management Engine (ME), also known as the Intel Manageability Engine, is an autonomous subsystem that has been incorporated in virtually all of Intel's processor chipsets since 2008.
