ECU Tuning

ECU tuning is for vehicle owners who want more power from their vehicles, or fleet owners who would like savings on their fleet operating costs.

For Power:

For vehicle owners who feel they want more. They want to go faster, quicker and enjoy the thrills of the ride.

  • Increased horsepower
  • Increased torque
  • Better throttle response
  • Smoother power delivery
  • Improved fuel economy
  • Safer overtaking

For Fleet:

Fleet owners are always looking for ways to reduce operating costs and the best ways we have found is to tune the vehicle for economy and limit the engine RPM to an area where you still achieve the power but are not overworking the engine, wasting fuel.

  • The improved economy in turbo diesel engines.
  • Reworking the torque limits on the engine at lower RPM you benefit from additional performance and improved economy.
  • Limiting the higher RPM the drivers will encourage to shift up through the gears and keep the engine running in its optimal performance window.
  • This is a very popular choice with large fleet owners where the extra mpg improvement counts on operating costs.

To achieve any of the above, we will first download the current ECU maps from the processing chip of the vehicle’s computer. Adjust various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance, torque values, and throttle pedal control amongst others to release the true performance from the engine. In doing this we do not change any hardware, but only modify the operating parameters in the ECU’s maps. Remapping will not only improve the engine’s power and torque figures, but it will also sharpen the throttle response and widen the power-band. This will make the power delivery a lot more linear and in turn, will make the vehicle feel a lot lively to drive. The other benefit of remapping will be a reduction in fuel consumption. With the extra torque, you should see a fuel-saving, as with the extra power it is easier to maintain cruise speeds. You will be able to drive in a higher gear at a slower speed as well as helping significantly when fully laden, towing.

Importance of Genuine Parts

The importance of using genuine filters is to protect you from unwanted expenses on your vehicle or equipment. In my view, the image says it all.
Even though genuine parts are slightly more expensive than aftermarket copies it is safer. At the end of the day you will save money in protecting your components. In this case he had fitted a ‘knock-off’ (non genuine) filter, and ended up paying dearly for this mistake.
By the time we got it the damage was irreversible.

Water Contamination Of Fuel During The Rainy Season

During the heavy rain season, one needs to take care of where you fuel your vehicles, as water contamination in fuel substantially increases. We see a great deal of Injector pumps and vehicles damaged to water contamination leading to expensive repair costs. To safeguard yourself and your vehicle, where possible use stations on high ground as the chances of water contamination in their ground tanks due to seepage is less likely. Fuel stations in low lying areas such as valleys are more susceptible to ground water finding its way into the storage tanks especially during flooding.

Water in the fuel can impact several different aspects of the vehicle / machine, it will

  • Corrode components.
  • Decrease the lubricity of the fuel.
  • Cause damage to the injector.
  • Cause damage to the Injector Pump / High Pressure Pump
  • Causes components to stick.
  • Block your fuel filter.
  • Cause components to become sticky and result in high return flow or high fuel delivery.

The more water your diesel contains, the more likely you are to suffer from the growth of microbes such as bacteria and fungi. The presence of water encourages microbial growth  also know as diesel bug contamination. Water has a detrimental effect on your engine. It will corrode components, encourage acid build-up, reduce lubrication and cause detrimental damage to you vehicles fuel system.
