What makes a good remap?

If you’ve ever felt your car lacking in power or responsiveness, you might have heard people talking about ECU remapping. But what exactly is a remap, and what makes a good one?

Here at Mobile Eco Tuning (MET), we’re specialists in ECU remapping, operating in Weston-Super-Mare and the South West, and we’re here to shed light on this exciting world of engine optimisation.

Beyond peak figures: The importance of a good remap

ECU remapping goes beyond simply chasing peak horsepower and torque figures. A good remap considers a multitude of factors to deliver a truly transformative driving experience. Let’s delve deeper:

Smooth power delivery

A good remap prioritises smooth, linear power delivery across the rev range. This translates to a more enjoyable driving experience, especially during overtaking manoeuvres or tackling hills. No more jerky power surges or frustrating dips.

Wide powerband

Imagine having a wider band of usable power at your disposal. A well-executed remap broadens the engine’s powerband, making power readily available throughout the rev range. This translates to effortless acceleration and a more responsive feel, especially in higher gears.

Crisp throttle response

Laggy throttle response can be frustrating. A good remap sharpens throttle response, allowing for more precise control over your vehicle. This translates to a more connected feel between driver and car, enhancing overall driving enjoyment.

Unparalleled driving experience

The culmination of these factors – smooth power delivery, wide powerband, and crisp throttle response – comes together to create an unparalleled driving experience. You’ll rediscover the joy of driving with a car that responds eagerly to your inputs and delivers a surge of exhilaration.

Beyond power: Improved driveability

A good ECU remap isn’t just about raw power. It’s about improving your car’s overall usability and driveability. Here’s how:

Reduced gear changes

With a broader powerband and improved torque, you might find yourself needing to change gears less frequently. This translates to a more relaxing and enjoyable drive, especially on longer journeys.

Improved towing ability

If you tow a trailer or caravan, a well-executed remap can make a significant difference. Increased torque translates to better pulling power, making hills and inclines less of a struggle.

Safety parameters: The importance of a good remap

At MET, safety is paramount. A good remap adheres to strict safety parameters to ensure the longevity and reliability of your engine. Here’s how:


In-house developed maps

We create our own custom maps in-house, meticulously tested on our dyno and real-world driving scenarios. This ensures optimal performance without compromising safety or exceeding your engine’s capabilities.

Lifetime software warranty

We stand behind the quality of our work. Our ECU remaps come with a lifetime software warranty, providing you with ultimate peace of mind.

Full diagnostic health check

Before any remapping takes place, we perform a thorough diagnostic health check to identify any underlying issues. This ensures a safe and reliable remapping process.

Petrol vs diesel tuning: Tailoring the remap to your engine

While the core principles of ECU remapping remain similar for both petrol and diesel engines, there are some key differences to consider:

Petrol Tuning


Petrol remaps typically prioritise horsepower gains and a more exhilarating driving experience. Adjustments are made to ignition timing, fuel pressure, and boost pressure (for turbocharged engines) to optimise power delivery.

Petrol remaps can offer significant increases in horsepower and torque, resulting in sharper acceleration and a more
responsive feel.

Diesel Tuning

Diesel remaps often target a balance between increased torque and improved fuel efficiency. The focus is on optimising fuel injection timing and boost pressure to deliver more torque.

Diesel remaps can significantly improve pulling power, making towing and uphill climbs effortless. Additionally, some remaps can see an increase in MPG.

Warranty and reputation: Choosing the right
remapping company

With so many ECU remapping companies out there, choosing the right one is crucial. Here are some key considerations:


A reputable remapping company will offer a warranty on their work, demonstrating confidence in the quality of their service.


Look for a company with a strong reputation and positive customer reviews. This indicates a history of satisfied clients and a commitment to quality remaps.

Industry standards

Ensure the remapping company adheres to industry standards and best practices. Look for affiliations with organisations like the Performance Automotive Aftermarket Association (PAAA).
