What is Remapping?

Remapping is an ideal way to increase and boost the car’s engine and performance. And since everyone wants better fuel consumption and performance for their vehicle, car remapping is the ideal way to achieve this; but what exactly is remap?

Remapping, also known as chipping, means altering the Engine Control Unit (ECU), which is responsible for numerous functions such as sensors, fuel injection or airflow. A car can function to its full potential by reprogramming and adjusting its system.

Car remapping is carried out in a number of stages, each providing greater benefits.

Advantages and Disadvantages of Remapping

Advantages and Disadvantages of Remapping:


Mainly, people opt for car remapping to enhance their speed and power, but it does bring other benefits:

  • It increases overall fuel economy and car’s mile per gallon, which helps in reducing your carbon footprint and saving money.
  • The car feels smoother and faster when pressing the accelerator.
  • Your vehicle will easily tow a vehicle as remapping gives extra power.


  • If your car is a non-turbo petrol model, your vehicle will not fully benefit from remapping.
  • After remapping, the car’s clutch can suffer from greater depreciation; therefore, it needs to be serviced more frequently.
  • After remapping, you may require higher octane fuel which is quite expensive.
  • If an authorised dealer does not carry out car remapping, it will compromise the car’s warranty and insurance.

Stages of Car Remapping

Car remapping is mentioned in 3 simplified different stages below:

Stage 1:

  • Stage 1 refers to vehicle performance and fuel economy.
  • It is done to gain and enhance more mpg to maximise the car’s performance.
  • It is achieved by file mapping and the upgradation of the induction kit or filter panel.
  • This file mapping is designed to enhance the vehicle’s performance without major mechanical alteration done to the vehicle.

Stage 2:

  • Stage 2 yields further and increases the vehicle’s power and performance via certain modifications.
  • These modifications may include a bigger intercooler, induction kits, turbos and a better exhaust system.
  • During this process, a sports car or a cat back is fitted while the original exhaust is also changed.
  • In doing so, the power limit will nearly reach the manufacturer’s power limit.

Stage 3:

  • In stage 3, the engine’s vital parts are changed and modified.
  • Extra time and a lot of customisation and extra time required, such as running the vehicle to check the health and existing power.
  • After this, the custom package is required; for instance, parts from stages 1 and 2 may need to be fitted, which is entirely up to the customer.

After considering the customer’s needs and requirements, further hardware is discussed to gain more vehicle power;

  • Supercharger and turbo pullies
  • Fuel pumps and injectors featuring up-to-date regulators.
  • Camshafts
  • Catch cans
  • Oil coolers
  • Nitrous or water meth injection

After stage 2, everything becomes much more personalised and depends on what the owner wants from the car and how much money he is willing to put into the car.

How Much Does It Cost to Car Remap?

The cost of remapping depends on the make and model of the car. However, you may need to spend around £150 – £400.

The cost may vary depending on the remapping and whether the customer opts for a car map switch. Moreover, the cost of car remapping is never paid upfront, it’s what you get in the longer term.
