Practically every modern-day engine in cars and also light office cars features a digital command device (or ECU for short), conversely called an engine management computer. This specialized and also complex system consists of a variety of computer chips and also essentially governs the operating of the engine. It is attached to different sensing units that identify fundamental aspects such as temperature (both in the engine and also externally), speed as well as exhaust gas structure. In a lot more sophisticated units, that are how to becoming progressively common, lots of other problems are taken note of. The ECU after that regulates various engine features, mostly fuel injection, ignition timing as well as boost stress if a turbocharger is fitted. The purpose is obviously to make sure smooth running, optimal gas intake and also efficiency, as well as marginal exhaust gas discharges.
Basically, there is no longer any kind of reason to consider engine remapping for either boosting performance at the expenditure of energy intake, or vice versa. There are a number of professional remapping business who will provide you the chance to have your cake and consume it!
