Essentially every modern engine in automobiles and also light industrial cars showcases an electronic control unit (or ECU for short), additionally recognized as an engine administration computer. This specialised and complicated system includes a number of computer chips and generally controls the running of the engine. It is linked to different sensors that discover basic elements such as temperature level (both in the engine and externally), speed and also exhaust gas structure. In a lot more advanced systems, that are coming to be increasingly usual, many various other problems are considered. The ECU then regulates different engine functions, primarily fuel injection, ignition timing and also increase stress if a turbocharger is matched. The purpose is obviously to make certain smooth running, optimal gas intake as well as efficiency, and also marginal exhaust gas exhausts.
In brief, there is not any kind of reason to take into consideration engine remapping with a view to either increasing performance at the cost of energy consumption, or the other way around. There are a number of specialist remapping companies that will provide you the opportunity to have your cake and eat it!
