With fuel prices still unpredictable, more drivers across Leicestershire are looking for ways to save money without sacrificing performance. That’s where a fuel economy remap — sometimes called an eco tune — comes in. At Leicester Remaps, we fine-tune your ECU software to improve efficiency and drivability at the same time.
How a Fuel Economy Remap Works
Every modern engine is controlled by an ECU (Engine Control Unit), which dictates how much fuel, air, and boost pressure the engine uses at any given time. Manufacturers leave a wide safety margin to account for poor-quality fuel and global conditions.
We carefully adjust these parameters within safe limits to improve combustion efficiency. The result is a cleaner burn — meaning less wasted fuel and smoother torque delivery at lower revs.
Unlike power-only maps, our Stage 1 remap balances both performance and economy, helping you get more miles from every litre of fuel.
Real Benefits of an Economy Tune
- Up to 15% better fuel economy on daily driving
- Smoother throttle response and stronger low-end torque
- Reduced carbon build-up and DPF regeneration frequency
- Lower CO₂ emissions and cleaner exhaust gases
- Safer overtaking thanks to improved torque curve
Many of our customers report savings of 40–80 miles extra per tank after tuning — especially on long motorway runs.
Case Study: Ford Transit Eco Tune
A local electrician came to us with a Ford Transit Custom 2.0 TDCi averaging 32mpg. After an eco-optimised ECU remap, the van now returns 38mpg on mixed driving — a 19% improvement. Torque delivery at 1,800rpm also increased, meaning fewer gear changes and smoother acceleration when loaded.
That translates to around £400 a year in fuel savings for a van covering 20,000 miles annually — without any mechanical changes or risk to reliability.
Is an Economy Remap Safe for My Engine?
Yes. All of our files are written to stay within the manufacturer’s safe operating limits. We never push boost pressure, fuel delivery, or exhaust gas temperatures beyond what your vehicle’s hardware can handle. Each file is tested using Autotuner and KESS tools for precise control and full data logging.
We also ensure that all DPF systems, EGR valves, and AdBlue modules remain fully functional for MOT compliance.
When to Choose an Economy Tune
A fuel economy remap is ideal if you:
- Drive long distances or commute daily
- Own a diesel car, van, or fleet vehicle
- Want smoother throttle response over outright power
- Need to reduce emissions for business fleet requirements
We also offer mobile ECU remapping — so you can have your vehicle tuned on your driveway or work site anywhere in Leicestershire.
Common Myths About Economy Remaps
“You can’t have power and economy at the same time.”
Actually, you can. Because torque delivery improves, the engine doesn’t need to work as hard, leading to lower fuel use during normal driving.
“Economy tunes make cars slower.”
Wrong. You’ll still feel a noticeable improvement in mid-range power — perfect for overtaking or towing, just without the aggressive top-end of a Stage 2 or Stage 3 setup.
“It’ll void my warranty.”
Our IMI-accredited technicians write every map in-house, and your car’s original software is always backed up. We also offer a lifetime software warranty for full peace of mind.
Economy Remap vs Performance Remap
It’s a balance. While a performance tune aims for maximum power and torque, an economy tune targets the efficiency curve. Most drivers choose something in between — a refined Stage 1 remap that improves power by 15–25% and fuel economy by up to 10%.
If you’re not sure which is best, we’ll assess your vehicle and recommend the safest setup for your driving style.
FAQs About Fuel Economy Remaps
How long does the remap take?
Typically 60–90 minutes. Our mobile team completes the process on-site, including diagnostics and road testing.
Will my MOT emissions change?
No. The remap optimises combustion, often resulting in cleaner exhaust readings during your MOT test.
Can you do economy remaps on petrol cars?
Yes — although gains are smaller than on diesels, smoother throttle response and reduced fuel use are still noticeable.
