The first thing you might ask about ECU remapping is, well, what is it? With all the mod cons at our disposal in this day and age, it can often be difficult to choose which are worth investing your hard-earned money in, so it’s important to have a clear idea of exactly what you are purchasing before you do so. In the majority of modern vehicles, you will find an Engine Control Unit, commonly known as the ECU. As you may have gathered from the name, it’s a small computer unit that controls how the engine works. Due to the diversity of rules, regulations, climates and other variables, the manufacturers ensure the software is reset before it is sent out to the dealership.
