Diesel tuning, also known as flash tuning, involves reprogramming the Electronic Control Unit (ECU) within your car in order to modify how the engine within your diesel vehicle works. This is usually done to improve your vehicle’s performance.
As a standard within most vehicles, the ECU is set to limit your vehicle’s functionality. In 4WDs, the ECU acts as the brain of the car, controlling several different aspects from the operation of your turbocharger at specific RPMs, fuel control under acceleration and deceleration to advising you when you are due for service.
Diesel tuning can impact various systems within your 4×4 vehicle including:
- Your engine’s performance and output
- Automatic transmission system
- Ignition and timing systems
- Fuel system operation
- Valve timing operations
The ECU can be optimised specifically to suit how you intend to use your vehicle. Changing certain ECU settings will help improve your car’s performance when dealing with offroad adventures, touring, towing or just cruising. At Highfields Mechanical, our team of professional technicians are experts in customising the tuning of your diesel engine to suit your on-road and off-road needs.
Benefits of Diesel Tuning
Flash tuning helps you get the most out of your diesel engine. By reprogramming the ECU within your vehicle, you ensure that your vehicle works the way you want it to, not limited to how the manufacturer intended.
One way in which diesel engines can benefit from flash tuning is through an increase in torque for your vehicle. By increasing your vehicle’s torque, your vehicle will be better equipped to tow heavy objects, such as trailers. Additionally, diesel flash tuning improves the performance of your engine, as the parameters that the engine operates under are changed. This can increase the power of your engine and reduce turbo lag. When combined with greater torque, diesel tuning ensures that you can drive thousands of kilometres of Australia’s vast terrain with ease. An increase in torque and engine performance helps your 4WD not only navigate rugged terrain but sealed roads too.
Depending on your requirements, diesel tuning can also improve the fuel economy of your vehicle and save you money in the future. With the right diesel tuning, you will be able to travel greater distances using less fuel than you would in a vehicle that has not been optimised.
In short, diesel tuning has the potential to be extremely beneficial for your 4×4 vehicle and can be customised to suit your day-to-day driving requirements.
Diesel Tuning Considerations
When done properly, diesel tuning is a great way to customise how your vehicle runs. However, if diesel tuning is not conducted by a professional, serious long-term damage could be done to your car.
It is important to consider how complex the ECU system within your vehicle is before altering the default ECU settings. Simply playing around with the settings, maps and codes within your vehicle’s computer system may change the functionality beyond what your 4WD can handle, setting it up for failure in the future.
Before undergoing flash tuning, it’s best to ensure that your vehicle is working at its optimum performance by getting a diesel service or car maintenance.
