Economy Tuning Files

ByteFLASH Economy tuning software is specifically designed to optimise your vehicle's fuel efficiency, reducing running costs and environmental impact while still delivering enhanced performance. Our economy tuning files are crafted to work safely on unmodified vehicles and remain within the original OEM safety tolerances.

These specialised tuning files adjust multiple engine parameters to improve fuel efficiency during everyday driving, particularly at steady throttle and lower RPM.

This is achieved through carefully calibrated changes to injection timing, fuel rail pressure, and torque request mapping. For example, some diesel engines run very retarded injection timing at cruise, which leads to inefficient combustion. By advancing injection timing in these load windows, improving fuel atomisation with modest increases in rail pressure, and promoting stronger low RPM torque to reduce frictional and pumping losses, we help the engine extract more usable energy from the same amount of fuel.

Benefits of Economy Tuning

Our Economy tuning files provide an excellent balance of efficiency, performance, and reliability.
Most customers can expect:

  • 2-6mpg improvement fuel efficiency on average.
  • 10-20% increase in power and torque when needed.
  • Smoother power delivery throughout the rev range.
  • Reduced emissions during normal driving conditions.

Tried and tested

ByteFLASH economy tuning software has been extensively tested in house, proven by individual customers, and refined on multiple large vehicle fleets.

Lower Emissions

Reduced fuel consumption means lower carbon emissions. Our fuel economy software has a positive impact on the environment and your pocket.

Safer driving

Tuning software isn't just about driving quickly. Additional power can make for a safer experience when over-taking or joining fast moving traffic.

Frequently Asked Questions


Yes! A lot of the fuel savings come from a more complete burn of the fuel, extracting more energy from the same fuel quantity. This means at cruising speeds less fuel is required, whilst under full throttle the additional energy extracted from the fuel makes for additional power and torque.

Yes! In most cases vehicles running our economy software will actually pass an MOT easier due to the lower emissions output when using our economy software. The absolute worst case is emissions remain the same during static MOT testing, and benefits are only seen on the road.

Well developed economy tuning software will not reduce the life span of your engine. All of our software is designed to work safely on a standard vehicle and within the capabilities of factory components. Of course we do see a lot of badly developed engine software in the market, which can and does harm engines. We urge customers to choose high quality software such as ByteFLASH when looking to save fuel and reduce their emissions output.
