Many piggyback systems offer single or multichannel outputs of the modified signals for use in other external electronic controllers or displays. These include boost control, drive-by- wire throttle control, two-step launch control and nitrous injection. This information is then fed back to the EMS which will adjust the fuel flow to maintain the correct AFR. The Engine Control Unit is a central part of the Engine Management System which is virtually the 'Brain' of an engine. Strategies are explained for modeling and controlling the airflow, exhaust gas recirculation (EGR), variable geometry turbocharger (VGT) vane position, fuel injection, and spark advance. • The job that engine management systems must complete for each engine cycle is to first measure all of the controlling variables which control its internal look-up tables (or maps) as it is required to make a firm decision quickly on the ignition event angle which is to be used for this cycle, then it must also make a firm decision on fuel delivery and decide on an injector … If there's a problem, the sensor will tell the engine control unit (ECU) which will turn on the engine management light. There are re-flash units on the market that also feature datalogging capabilities, real- time map adjustment and on-the-fly map changeovers. If the ECU has control over the fuel lines, then it is referred to as an electronic engine management system (EEMS). This is an advisory warning, which indicates an engine issue that affects emissions. The tradeoff is that the ranges and levels of adjustability are not as broad as a ROM tune or stand-alone ECUs. 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. It plays an important role in collecting, analyzing, processing, and executing the data it receives from various sub-systems. Read more: Which are different engine sensors and how they work? Additionally, because stand-alone units generally offer control over more possible map combinations, they take longer to complete the initial tune without a good base map supplied by the manufacturer. Furthermore, an ECU comprises a computer that uses a microchip to process the inputs from various engine sensors in real-time. The CAN bus physical layer defines things like cable types, electrical signal levels, node requirements, cable impedance etc. Because the units have their own internal memory, there is no physical or electronic modification necessary to the ECU.
