What is Engine Remapping and Is It Worth It? | GVE London – Blog

Those who make the heavy investment of purchasing a supercar have a singular thing in mind: the need for speed. Obvious references aside, supercar owners want the best possible performance out of a machine, which is why they purchase one capable of it. However, did you know that you can get even more performance out of a car’s engine? That’s right. In this blog, we’ll talk about the practice of engine remapping.

What is Engine Remapping?

Engine remapping is a legitimate and widely practiced method used by customisers and modders (those who perform modifications) across the globe to get the most out of an engine. It is done by essentially controlling the car’s Engine Control Unit (ECU) software. If you’ve seen the movie Lucy, you might recall how the main character attains supernatural abilities by unlocking the power of their brain. Now, engine remapping won’t give your supercar supernatural abilities, but a technician can adjust the software parameters to rid the car of any limitations and get the most out of it.

What does that mean in real terms? Well, it results in improved horsepower, torque, and fuel efficiency.

Whilst most engines can be remapped, some engines are more “mod-friendly” than others. For example, the 2JZ—specifically the 2JZ-GTE—is a legendary 3.0-litre inline-six, twin-turbocharged engine known for its high hidden potential, which could, with engine remapping, achieve a mind-boggling 1,000 horsepower.

Benefits of Engine Remapping

By performing supercar engine remapping, you can expect the following advantages:

• Better Performance: That’s the entire point of this. By lifting any restrictions set upon your engine, remapping can increase your car’s horsepower and torque, and thus its performance.
• Better Fuel Economy: This highly depends on the type of modifications you get. A specific style of engine remapping could result in better mileage; however, simply increasing the power figures would likely decrease fuel efficiency.
• Make It Your Own: When you remap an engine, you can customise it your way. The car’s engine can be tuned to suit your driving style to an extent. To get the best out of your car’s hidden potential, though, you should consider equipping it with other aftermarket upgrades, like a performance exhaust or a turbocharger. Do note that all parts should ideally be sourced and installed by a trusted supercar service centre like GVE London.

But Are There Any Risks?

Similar to other modifications, engine remapping can be a complicated procedure with a few downsides. For example, it will void warranties if your car is still under warranty. Some dealers may allow it, but it’s best to make sure beforehand. Secondly, modifications must be declared to your insurer, as they affect premiums and coverage.

However, those who are into modifying their supercars already understand the above. We’d like to emphasise the value of experienced technicians. You do not want an average Joe remapping your engine, as it can lead to engine strain or reduced reliability. Always choose a reputable supercar service centre with experienced technicians who specialise in your type of car.

Conclusion

Supercar engine remapping is a tried and tested method that has been a part of car culture since, almost, its origins. For those wanting more performance out of their car, it’s the way to go. However, make sure to visit a reputable supercar service centre for the best results.
