Economy & Fleet Tuning

When we remap a vehicle for economy the focus is on improving the low end torque, this will mean the accelerator be required to be used less to maintain cruising speeds, when fully laden or when on a gradient. It will also mean that the vehicle will be more comfortable in higher gears at slower speeds as well requiring fewer gear changes overall.

Combined  with adjusting your driving style to make the most of the extra low end torque you will see an improvement in fuel consumption. This is most effective on turbo-diesel engines where the savings could be as much as 20%

✓ Up to 20% savings on the cost of fuel

No mechanical modifications

✓ Minimal downtime for vehicle

✓ One-off installation fee

✓ Possible return on investment within 6 months or less

A tuning company called Viezu was possibly the first to conduct case studies on the effects of making fine ECU software calibrations with the primary focus to deliver better fuel consumption and reduced CO2 emissions, while also improving vehicle driveability. I’m not saying these case studies were 100% scientifically accurate as there are so many factors to take into account, but they were real-world figures and convincing enough to gain the contract to carry out the work on 24,000 British Telecom vehicles, delivering estimated fuel savings of £3 million.
Below are some of the results from the case studies:

A fleet of 10 x 2009 Ford Transits driving loaded and towing in an urban environment over 6 months saw an 8.4% fuel saving.

A fleet of 25 x 2012 Mercedes Sprinters part loaded with start / stop urban driving over a 3 month period saw a 23% fuel saving.

A fleet of 10 x 2013 VW Caddys in an urban environment during a 1 month period saw a 12% fuel saving.

Our Top Fuel Saving Tips

1. Slow Down
One of the best ways to save fuel is to simply reduce your speed.
2. Careful Braking
Every time you brake, you convert fuel that you have paid for into heat!
3. Planning
Plan ahead, watch for traffic; choose the best route, not always the shortest.
4. Use Gravity
On a modern vehicle it uses no fuel when your foot is off the accelerator, so take
advantage of downhill runs, or approaching a junction; it’s completely free motoring!
5. Accelerate With Care
Accelerate smoothly and gently, maintain a constant speed, and keep gear changes to a minimum.
6. Top Gear
Get into top gear as soon as possible, without labouring the engine as each gear down can cost up to 20% fuel.
7. Switch The Aircon Off
Up to 10% fuel saving
8. Keep It Serviced
Under-inflated tyres are one of the most commonly ignored causes of poor MPG, consumables such as a dirty air filter
restricts the flow of air into the engine, which harms performance and economy, it’s also important to use quality oil.
9. Have A Remap
With a diesel-engined vehicle, you can significantly improve fuel consumption by having a remap.

Fact is that no one has a miracle cure or gadget to save both your pocket and the
planet, BUT when you have a RubyTune Remap you can experience substantial fuel savings and
these days, every little really does help.
Realistically, most turbo-diesel vehicles can see a 5-15% fuel saving from the remap. BUT,
it needs to be combined with a change in driving style to take full advantage of the extra torque and drivability.
However, use the extra power, drive hard and convert all the extra power into acceleration or
higher speed and savings will be minimal, if at all – but you will have fun!
