Every year, Earth Day serves as a powerful reminder that our small, everyday choices have a lasting impact on the planet. While many environmental campaigns focus on walking, cycling, or switching to electric vehicles, there’s another highly effective—yet often overlooked—option that drivers can take advantage of today: tuning and remapping their vehicles for improved fuel efficiency. Offering the opportunity for Fuel Savings.
At VIEZU Technologies, we specialise in precisely that. Our team has helped enhance the efficiency and driveability of over 300,000 vehicles, offering tailored engine remapping solutions that not only improve fuel economy, but also help reduce emissions and make driving more enjoyable.
Why Fuel Efficiency Still Matters in 2025
Despite the growing adoption of hybrid and electric vehicles, internal combustion engine (ICE) cars, vans, and motorhomes still make up the vast majority of vehicles on the road. For the millions of people who rely on petrol or diesel-powered vehicles, improving fuel efficiency is one of the most practical ways to lower emissions and reduce operating costs.
The challenge? Manufacturer fuel economy figures are notoriously difficult to achieve in real-world driving. Whether you’re dealing with traffic, hills, or heavy loads, your vehicle is probably working harder—and burning more fuel—than advertised.
Even with the advent of supposedly more accurate WLTP vehicle testing methods, it’s often very difficult to achieve manufacturer published economy figures in real world driving conditions.
How Tuning Improves Efficiency
A professional engine remap works by reprogramming the vehicle’s ECU (Engine Control Unit) to optimise how the engine delivers power and torque. Rather than adding unnecessary top-end performance, efficiency-focused tuning carefully calibrates power delivery in the low to mid RPM range, where most everyday driving happens.
This means you get more usable torque, smoother acceleration, and far less need to press hard on the accelerator—especially useful in urban driving or when towing.
More power and torque in the optimum part of the engine’s range… means that you need to use less throttle input. This results in less fuel being used.
Real-World Gains: Up to 20% Fuel Savings
VIEZU’s BlueOptimize and blend tuning solutions have demonstrated fuel savings of up to 20%, depending on vehicle type and usage. These figures aren’t just theoretical—they’re based on years of development and testing across cars, pickups, vans, and motorhomes.
Case in Point: The Ford Transit Motorhome
Take a 2014 Ford Transit-based motorhome. From the factory, it delivers 119hp and 360Nm of torque. After a VIEZU remap, this model was transformed to produce 171hp and 437Nm of torque—a substantial improvement that allows the vehicle to hold higher gears for longer, climb inclines more confidently, and do it all while using less fuel.
The Environmental Benefit
When your vehicle uses less fuel to perform the same job, it burns fewer hydrocarbons—reducing CO₂ output per mile travelled. Multiply that by thousands of miles per year, and the impact becomes significant.
Fuel usage reductions of up to 20% become instrumental in achieving substantial savings in running costs and contribute to emission reduction.
Everyday Efficiency: Who Benefits?
You don’t need to drive a high-performance sports car to benefit from tuning. In fact, some of the biggest gains are seen by:
– Commuters: Less throttle input in stop-start traffic = real savings
– Tradespeople: Vans and pickups carrying tools or equipment burn more fuel—tuning helps offset the load
– Towing Vehicles: More torque at lower revs makes for smoother towing and better MPG
– Motorhome Owners: Heavier vehicles benefit from tuning more than most, especially in hilly regions
– Eco-Conscious Drivers: Reduce your fuel usage and emissions without giving up your petrol or diesel car
Add Flexibility with Switchable Drive Modes
For those wanting greater control, VIEZU offers personal tuning devices. These allow you to store and switch between multiple engine maps, with options such as:
– ECOME – maximised for fuel efficiency
– FUSIONME – a balanced map combining efficiency and power
– EXCITEME – enhanced performance for performance driving
– CLASSICME – revert to factory settings at any time
– THRILLME – designed for track day use (where supported)
Depending on your specific vehicle, the device can provide you with up to 5 different drive settings… switch between them in under 15 minutes.
Safe, Tested, and Guaranteed
At VIEZU, we take quality and safety seriously. That’s why all tuning is backed by a 30-day money-back guarantee.
Our remaps are developed using our in-house 3,000hp 4WD dynamometer, and we carry out extensive testing before releasing any file for customer use. It’s this focus on quality and detail that has earned VIEZU numerous awards, including the prestigious Queen’s Award for Enterprise: Innovation.
Tuning for a Cleaner, Smarter Drive
Earth Day is about taking meaningful action—and tuning your vehicle for better fuel efficiency is one of the smartest, most immediately accessible changes you can make.
