Essentially every contemporary engine in autos and light commercial vehicles includes an electronic command device (or ECU for short), alternatively known as an engine management computer. This specialized and complex system contains a variety of computer chips as well as basically regulates the running of the engine. It is connected to various sensors that find standard elements such as temperature level (both in the engine as well as externally), speed and exhaust gas structure. In much more innovative devices, that are ending up being significantly usual, many various other problems are thought about. The ECU then manages different engine features, primarily gas injection, ignition timing and improvement pressure if a turbocharger is matched. The goal is undoubtedly to make certain smooth running, optimum gas consumption and also efficiency, as well as marginal exhaust gas emissions.
In other words, there is no more any reason to think about engine remapping for either raising performance at the expense of fuel consumption, or vice versa. There are a number of professional remapping companies who will certainly offer you the possibility to have your cake and also have it!
