      The Roo Systems customised tune is designed to produce an increase in power, torque and improve fuel efficiency to allow better drivability.

      Roo Systems have spent thousands of hours testing and tuning our products and invested a lot of resources on research and development. Our products are constantly being tested in the bush, on the beach, as well as towing both caravans & camper trailers. There are NO companies that test their products as extensively as we do!

      The benefits of having a Roo System tune include ease of overtaking and maintaining comfortable cruising speeds, and more power when you are driving off-road. And if you’re fully loaded or towing, you can comfortably maintain the legal road speed and you won’t find yourself slowing down on long hills with a line of motorist backed up behind you!

      If you want a specific tune for towing Roo Systems  will tailor that to allow responsiveness of your vehicle to make it easier and more drivable.

      ECU (factory computer) tuning refers to the process of replacing the original factory installed map used by the ECU of the vehicle to a custom tuned version. 

      Do vehicle manufacturers do this? Yes, they do. 

      Do you think that there is a difference between the stock/base, mid-spec and the luxury sports model variants of vehicles? Do you think you get a different engine with every facelift of a car? 

      Manufacturers build an engine and design it to give optimum power and performance, they are governed by many factors, saleability, economy, emissions etc. 

      The process of remapping a vehicle is usually one to two-day process (most same day), as every tune is customised to each vehicle and not all ECU’s are identical in the same model vehicles. 

      ECU remapping is a complex and comprehensive procedure to alter a number of key parameters in the vehicle’s ECU including injection timing, boost control, fuel delivery and torque limiters to name a few. 

      Roo Systems has been carrying out research and development for the past seven years to refine ECU tuning to suit most of the popular 4WD vehicles to suit Australian conditions before launching into market (with many more makes and models to come), so you can be assured that our tunes are at the pinnacle of quality to suit your diesel 4WD. 


       Why Remap? 

      More power

      Greater Torque

      Better fuel economy ( *depending on vehicle and use )

      Enhanced, sharper throttle response

      Smoother, more progressive delivery of power

      Reliable and safe way to power up your 4WD


      The gains you will experience is a substantial increase in power and torque by up to 40% that develops a much smoother and more responsive driving experience for your 4WD. Another significant benefit you will experience is a fuel saving of up to 20%. All this extra power, torque and economy are achieved while still staying within the factory safety parameters and backed up by our own Roo Systems warranty.
