1. What is car customization?

Cars come “pre-programmed”, with hundreds of functionalities that are either activated or deactivated by the car manufacturer.

For example, the start/stop system comes activated in lots of vehicles. However, many people find the start/stop system annoying and would rather not have it.

Another example are the Welcome Lights. They are pre-programmed to only behave a certain way, such as blinking two times. However, many car owners would like to customize the Welcome Lights to blink more times.

Luckily, deactivating (or activating) these functionalities is possible, legal and very easy to do! This is called car customization, or also car coding. It is basically the configuration of your car’s software.

With your OBD2 scanner and mobile app you can do it yourself by just tapping one button! In the same easy way that you can change your phone’s background image, you can also change your car’s software settings. Below we explain how to perform your own car customization!
