Tune Types: 

We understand that everyone is different so we put together some options to suit everyone.

Factory Tune

Switch back to the factory tune at anytime. This may be used when returning your car to the dealer for servicing

Valet Mode

This option is very popular for people that often leave there car with a 3rd party, whether it’s a hotel or car cleaner. This limits the power and the vehicle cannot be taken past half of its total rpm range. Excellent safety feature.

Linear Tune

This tune is design to be super smooth. Bringing on the power smoothly is perfect for the person that is happy with the factory tune but wants a linear increase in power across the entire rpm range whilst still providing the maximum achievable power suited to your modifications.

Aggressive Tune

This is our most popular tune. This tune brings on the power as quickly as possible. Feel the rush as your turbo brings on the torque and plants you firmly into the seat. Engineered for maximum performance in the low, medium and high rpm range this tune will certainly excite you all the way to the redline.

Motorsport Tune

This tune is for motorsport use only. Please contact us for this option.

Tuned your way, Tuned for your car!

Upgrade Package:

Upgrade to the Multi Tune Package which gives you the Factory Tune, Valet Mode, Linear Tune & the Aggressive Tune. Whether you’re out on the Race track or daily driving, this allows you to swap tunes to suit and condition or occasion.

*Upgrade package not available for all vehicles.

How does the ECU Tune Builder Work?

Simply use the drop down menus to select your vehicle model and any modifications that have been made to it.

Why is it important to select which modifications have been made to the vehicle?

Each tune is specifically tuned to your car, listing the modifications helps us make particular changes to certain parameters of the tune so that you’re getting the maximum benefit from your modifications

What if my car is standard with no modifications?

If you have no modifications on your car or aren’t sure by some of the menu options just simply leave the options as standard. Some of the best performance gains are made on a standard vehicle.

How is the tune programmed into my Car?

You will be sent a SpecTune Controller to your nominated address. Inside the box is a special proprietary touch screen device. Simply plug it into the cars OBDII port. The software will load and take you step by step through the process. Your standard ECU (engine control unit) file is sent to us and shortly after you will receive the updated tune suited specifically to your car. A full user manual is available here

What if I make more upgrades/modifications at a later date?

If you add more modifications to your vehicle and want the tune updated to suit and to take your car to the next stage, simply login to the website and purchase our Tune Upgrade Package. You will be sent the modified file/s and it can then be loaded into the car via the SpecTune Controller.

*If the car has extensive components changed like an aftermarket turbo charger an additional fee may apply.

How long will i have to wait for my SpecTune Controller?

We will dispatch it the same day as the order and payment is received

Can i re use the SpecTune Controller on another vehicle?

Yes. If the original file is transferred back to the ECU then the SpecTune controller can be used on another vehicle.

What if i want to change tune types?

No problems. Just plug the SpecTune Controller back into the car and use the intuitive touch screen to load one of your other tunes available that come with your purchase

Now its time to enjoy your new engineered performance!

About SpecTune

SpecTune unlocks the true performance of your vehicles engine through advanced ECU Tuning resulting in an increase to vehicle power and torque safely throughout the entire RPM range. 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 3rd 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.
