Everything You Need To Know About Engine Remapping & Car Chipping

In the world of car performance, there’s always the pursuit of the next level of power, efficiency, and responsiveness. Engine remapping and car chipping are two popular methods for achieving those goals. But what exactly are they, and how do they work? Are there any potential downsides? This article will cover everything you need to know about engine remapping and car chipping.

What is Engine Remapping?

Engine remapping is the process of modifying the software in your vehicle’s Electronic Control Unit (ECU) to improve its performance.


The ECU is the vehicle’s “brain,” which controls various aspects of the engine, including ignition timing, air-to-fuel ratio, and turbocharging pressure. By tweaking these settings, it’s possible to extract more power, torque, and responsiveness from your engine.

Performance tuning

Performance tuning involves altering the ECU settings to increase engine performance. The new settings are often referred to as “maps,” which are optimised for different driving conditions, fuel types, or even specific tracks.

What is Car Chipping?

Car chipping, also known as chip tuning, is another method for enhancing vehicle performance. This process involves physically replacing or modifying the ECU chip, rather than altering the software.

Chip tuning

In the early days of ECU tuning, car chipping was the primary method used. Nowadays, remapping has become more popular because it’s often easier and less invasive than physically replacing the ECU chip.
