Q: ”What about my factory warranty?”

A: Simply put, no; an ECU Remap performed by Diesel Tuning Brisbane will not void your factory warranty.

WHY: The processes used in tuning at Diesel Tuning Brisbane will not cause detriment to the hardware of your vehicle. The research and developement conducted by professional tuning techncians at Diesel Tuning Brisbane ensures that optimum performance and economy are obtained with respect to optimal cylinder pressures, combustion temperatures and turbocharger speeds with optimal air density.  DTB are proud to report a 0% comeback and warranty rate from our tuning. At DTB we work in collaboration with OEM’s and Dealerships, being provided with access to tehcnical data to ensure our tuning is safe.

Why does my dealer tell me this?

Dealerships must maintain a parellel cohesion with the OEM to maintain their dealer agreement, which means followign corporate guidelines. Some on the other hand are renowned for voiding warranties for items as simple as aftermarket tyres and wheels, and do so to prevent any re-work at their expense which is otherwise not billable to the OEM corporations. 

Q: “I can get this cheaper”

A:You probably can, but what are you actually getting?

What do you mean?

There are organizations that offer “ECU Remapping” at discounted, or very low rates. It is important as a consumer, that you understand the differences of genuine tuning technicians and “Flash Tuning” where a provider will simply purchase a file and load it to your vehicle with no clue what the data entails and no chance of re-loading your original platform. Be wary of clever marketing and cheaper prices. Some are deceiving and may appear well-equipped on the surface, however it is of utmost importance that you fact check your tuner. Always remember, qulaity work is never cheaper, and cheaper work is never better.

Q: “What about my fuel economy?”

A: It usually improves!

WHY: With more torque on demand with optimal tuning and greater thermal efficicy of the engine, this means that gives that less throttle is needed to accelerate ot maintain the same cruising speed, meaning that less fuel is needed throughout the combustion process. With our ECU Remap you will typically see savings between 10% to 20% in fuel consumption.

Q: “What if I’m not happy?”

A: We are yet to have a client unhappy with the result.


Because we take pride in our workmanship and offer premium level workmanship to ensure customer satisfaction. We’ve spent hours testing our method before releasing any sort of product to the public market. We guarantee improvements in Torque and Power or will restore your vehicle to standard free of any additional charge. 

Q: “What is a Diesel ECU Remap?”

A: An ECU Remap is the process of changing data and parameters inside the Engine Control Unit. Changes to maps and data making up the file which the engine operates on such as Boost Pressure, Fuel Injection Volumes, Injection Duration, Injection Timing, Throttle Response, Air Intake, Torque Modelling and Sensor Scalings can all be altered depending on the strategies employed by the OEM software engineers and how the engine reacts in response. This is the best way to increase performances and reduce fuel consumption of a Diesel Engine.

A standalone ECU or External Tuning Module can be used for extreme and high performance applications which also require tuning by a skilled technician.

ECU Remap vs External Chip Boxes

External “Plug’nPlay” Chips are unreliable and risky simply because they cheat the ECU by giving false readings of feedback values from various engine sensors in such a way that the ECU will add more fuel, more boost pressure or more fuel rail pressure. A false reading of a simple engine sensor could ultimately lead to turbo or engine failure.
