Tune Types: 

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

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!


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!
