Diesel Tuning

Tarmac Engineering specialise in custom tuning a wide variety of ECU’s that are found in Australian Diesel vehicles including Toyota Hilux & Land Cruiser, Nissan Navara, Ford Ranger, Isuzu Dmax and more

This unique process is accomplished by calibrating how the ECU communicates to the engines vital components to provide a true performance experience.

We employ an extensive process in developing vehicle software

1. Record thousands of datalogs from the vehicle in its factory state across all types of applications including controlled dyno cell, road driving, track racing and drag racing. Datalogs provide real time feedback of engine data including boost, air fuel ratio, ignition timing, intake air temperatures and hundreds more. Datalogs and Factory ECU algorithm is then studied.
2. ECU coding development. Before we start increasing engine performance we must understand exactly how the factory ECU works. SpecTune engage with industry leading software which gives us access to 100% of the code in the ECU so nothing is missed, everything is considered. Having complete access to 100% of the ECU gives us a huge advantage over our competitors which can be restricted to only a few maps given to them by poor 3^rd party software.
3. Performance development is started. As we slowly start calibrating all vital engine components to achieve increases in power and torque we strictly adopt the OEM safety mechanism code as used by the factory to ensure reliability and longevity of engine components. This process is carried out with factory hardware and then a variety of aftermarket hardware inlcluding Cold Air Intakes, Exhaust systems, upgraded fuel parts, intercoolers, DSG tunes and race fuel.
4. After we’re happy with our results the vehicle is tested in multiple environments to ensure optimized performance is achieved no matter what the driving conditions. Any fine tuning calibration will take place at this point and be retested.
5. SpecTune software for your vehicle platform is released and ready to enjoy.
