Engine Control Unit
An Engine Management System is now very common or even required on both high end and regular vehicles. Its also common for people to use the term Engine Control Unit (ECU) in place of engine management system. The engine management system is basically an electronic control unit (ECU)which receives signals from various sensors, make calculations and sends output signals to carry out various functions and operations within and around the engine. The main reason for a proper engine management system is to reduce emissions and achieve better fuel economy. Performance is also increased but vehicles before management systems used to perform well for their time but an engine management system achieves the performance figures with better fuel economy and less emissions. The benefits of an engine management system will be the same as the benefits of a fuel injected engine as fuel injection is controlled by an engine management system but there are some other benefits when a sophisticated and powerful system is used. Some of the other benefits of an engine control unit is that it can alter certain operations in the same engine to produce a different result.
