Car Remapping: Everything You Need To Know

Have you been considering car mapping? Or maybe you have been told you need to have your car engine remapped and aren’t sure if your vehicle requires it?

Essentially car remapping is a modification to your car’s Electrical Control Unit (ECU) to override the manufacturer’s factory settings. This type of modification can allow your vehicle to perform at its optimal level.

What is Your Car’s Electrical Control Unit?

Before you look at car remapping, you need to understand your ECU and what it does.

Your ECU is a computer in your car that governs the power of your engine in a nutshell. There are predetermined limits set to alter your car’s performance to extend the life of your vehicle.

Newer ECUs have onboard diagnostics ports – this is also used for remapping. These ports allow the ECU to be connected to an external computer to analyse issues with your car, thus increasing the functionality of your ECU.

Do All Cars Benefit From Remapping?

Typically only turbo engines will get the most benefit from remapping. The results will be negligible for other engines, although that’s not to say it isn’t worth doing entirely. It is important not to attempt to map your car yourself unless you are an excessively skilled mechanic. If not, you should leave this process to the professionals, which typically takes under an hour.  

Are There Benefits to Remapping?

Remapping was once thought of as something only “boy racers” or speed enthusiasts undertook to improve their car’s performance. These days, it is becoming more and more popular with drivers, most notably for the increased performance and speed acquired once your engine has been remapped. 

However, if you are on the fence about whether or not you really need to get your car remapped professionally, you can expect the following benefits.

• Economic – Remapping will help you to not only reduce your carbon footprint but will allow you to increase your fuel economy and MPG.
• A Better Ride – Your car will drive more smoothly and give you a better driving experience.
• Increased Pulling Power – No more issues when going up hills or accelerating.

If you spend too much time on the road or frequently drive across different terrains, remapping your car is the right option for you to get the most from your engine and reduce any drawback of being constantly on the road.

The Disadvantages of Remapping Your Engine

Be aware before you get your engine remapped, this can affect your insurance premiums due to the modifications being made, and your premiums may increase. Check with your warranty to make sure it isn’t invalidated due to making the modifications.

Another fundamental problem with remapping is that it can increase the strain on your car, meaning you may find you need increased visits to your mechanic to help support your car. 

There is no denying that car engine remapping is now more mainstream than it once was, and as such, more and more car owners are choosing to have this type of modification to increase their driving experience.
