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.
QUESTION: Do vehicle manufacturers do this?
ANSWER: Yes they do – read on!
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.
Here’s an example, the Audi 2.0TFSi, we can see that this model is sold globally at different levels including 180hp, 200hp, 210hp, 220hp, 225hp, 240hp, 265hp, 280hp and 300hp. The reasoning behind this is to sell as many units as possible. Audi builds an engine to be powerful, then strangles the power out of the engine and sells it at a much lower spec/performance level, e.g in the base model. Audi then adds sports trim and new wheels and all of a sudden you have a brand new model car? Wrong! It’s just a modified variant with the same motor tweaked by software – and another unit for the manufacturer to sell.
An additional benefit for the manufacturer is that due to their global thirst for emissions and taxation implications (which in many cases would rule out certain engine varieties due to higher power outputs and emissions), a simple software alteration can fix these issues and be another revenue stream for the manufacturer to pursue.
So does this apply to 4WD’s?
It sure does! Manufacturers do exactly the same with 4WDs and the real benefits of ECU Tuning are:
- More power
- Greater Torque
- Better fuel economy
- Enhanced, sharper throttle response
- Smoother, more progressive delivery of power
- Reliable and safe way to power up your 4WD
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. 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 5 year warranty.
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.
ECU tuning can be carried out at our Roo Systems head office in Banyo Brisbane or at a selected Roo Systems premium dealer Australia Wide. For more information on what Roo Systems can do to your diesel 4WD call our national sales hotline 1300 305 709.
