Car coding refers to modifying or reprogramming a vehicle’s electronic control units (ECUs) to unlock hidden features, enable additional functions, or customise settings according to your preferences.

Modern cars are controlled by software, and manufacturers often include features that are hidden or disabled depending on the model, trim, or market. With car coding, you can access and activate these features without needing major hardware changes.

⚠️ Important Notes

• Not all cars support the same coding features (depends on brand, model, and year).

• Some changes may void warranty or cause errors if not done correctly.

• Always back up your original coding before making changes.
