You\u2019ve probably heard of OBD remapping but might not know exactly what\u2019s involved. At Top Tuning, we\u2019re here to help.<\/p>

Remapping is when technicians reprogram the software in your vehicle\u2019s ECU (engine control unit). An ECU is standard on today\u2019s vehicles and it controls the way your vehicle drives. It determines your fuel consumption, acceleration, how fast you can go and even how the vehicle handles.<\/p>

Chances are, the software that the manufacturer has installed will limit your car\u2019s true performance. This is to comply with environmental noise and emission regulations.<\/p>

These programs also restrict engine power. This is so that manufacturers can use the software to provide a range of power variants with the same engine. An ECU remap reprograms the software within the parameters of mechanical safety. As well as \u2018remapping\u2019, some people call the process \u2018chip tuning\u2019.<\/p>

Remapping is relatively straightforward, once we\u2019ve done the development work that tells us optimal performance and fuel-efficiency balance. We never remove or add any components, although we might sometimes need to take out the ECU to remap it.<\/p>

Will ECU remapping improve my car\u2019s performance?<\/strong><\/p>

So what will you gain from ECU remapping? In short, the way your car drives will be completely different. The specifics of that depend on the tuning options you select. But in general, you\u2019ll be looking at:<\/p>
