Practically every contemporary engine in automobiles and also light business cars includes an electronic command device (or ECU for short), additionally referred to as an engine management computer. This specialized as well as complicated system includes a number of computer system chips and generally governs the operating of the engine. It is attached to different sensors that spot basic factors such as temperature level (both in the engine and on the surface), rate and also exhaust gas structure. In much more sophisticated units, that are how to becoming increasingly common, many various other problems are thought about. The ECU then controls different engine functions, largely fuel injection, ignition timing as well as boost pressure if a turbocharger is suited. The objective is clearly to make sure smooth running, optimal gas consumption and also performance, and also minimal exhaust gas exhausts.
Simply put, there is not any type of factor to think about engine remapping for either raising performance at the cost of gas usage, or vice versa. There are a number of professional remapping firms that will provide you the opportunity to have your pie and also eat it!
