Chiptuning, how does it work?

Chiptuning, or ECU tuning, is becoming an increasingly popular way to optimise the power and fuel consumption of a car. Car owners have a so-called remap done by a software specialist. This gives the car more power and reduces fuel consumption. But what exactly is chiptuning? How do you choose the right tuner and what should you pay attention to? You can read all about it on this page. 

What is the ECU?

The Engine Control Unit regulates the operation of the entire engine and its components, including electronic systems (ABS, ESP, TCS) and other equipment, such as air conditioning. The ECU is therefore the 'brain' of the whole computer that determines the technical possibilities. The engine control unit is usually a microprocessor (the chip) that receives and processes data. The data comes in from various sensors, such as the air mass meter.

During production, manufacturers save universal settings of the operation in the computer memory of the car, but they are not optimised for the conditions in which the car is driven. These settings partially determine the car's performance, such as the engine speed, fuel dose, injection angle, turbo pressure (if present) and fuel injection pressure. Based on this data, the ECU selects the optimal parameters for the car's performance.

What is chiptuning?

Auto remapping, also known as chiptuning or ECU tuning, is an extremely effective and safe method for tuning engines. Engine tuning (new software) is designed to increase the engine torque and power. This can be done in two ways: by mechanical interference in the engine or by optimising the software. The first method is very expensive and often requires customisation.

Chiptuning is a simple and, most importantly, safe way to change engine operating parameters and increase efficiency. When reprogramming a car, new software is uploaded that enables more efficient engine operation. 

Why does chiptuning work?

Standard software installed during the production phase does not extract the maximum potential from the engine. By using better software, it is possible to safely increase engine capacity and achieve significant power gains without damaging the engine. Moreover, changing these values can translate into better fuel economy. In some cases, this can save up to one litre per 100 kilometres. If you drive a lot, then the investment in chiptuning is quickly recouped. 

For successful reprogramming, it is important that the software is adapted to the vehicle model and the capabilities of the engine and its components. Chiptuning with unsuitable software can lead to the vehicle becoming defective or even permanently damaged. 

Choose an experienced chiptuner 

The advantages of chiptuning are tempting and more and more people are choosing to do so. This is partly due to the low costs compared to mechanical tuning. But it is necessary to choose an experienced chiptuner who has a lot of experience in tuning your brand and model.
A company that does not know much about chiptuning may overestimate the car's capabilities and this can lead to damage and malfunctions.
