Revo Performance ECU Software for the 2.5TFSI transforms the way in which the car can be driven. Out of the box, the RS3 demands attention and respect, and rightly so. With 400PS and 480NM torque, an incredible 5 cylinder soundtrack, less weight than the previous model and impressive acceleration times, all the right ingredients are there. Revo ECU Software unleashes the cars full potential and boasts a staggeringly impressive 490PS and 590NM torque, that’s +90PS and +110NM more torque than it rolled out of the factory with.

Intensively tested and refined over twelve months, throttle response has been dialled in to give the driver a deeper sense of connection and involvement with the car, something the stock model seems to lack. Rather than being pulled, the hike in torque gives the feeling of a firm push from the bottom of your back, and it’s addictive. The car now begs to be driven hard, it’s now able to break traction in corners, and dares you to bury your right foot. Optimised power delivery and with much more torque at its disposal, you can now drop below 4000rpm and still pull hard out of any corner without hesitation.


A common issue shared with the pre-facelift 8v RS3, the 2.5TFSI is extremely sensitive to heat and fuel quality. Initial stages of Revo’s Software development process involve pushing the engine harder than usual to find limitations and restrictions. The team found that running more power and torque offered no improvements in acceleration times, negatively affecting the cars ability to consistently perform. Exhaust gas temperatures (EGT) were found to reach up to 960ºC when stock, this highlighted the importance of monitoring EGT’s to avoid risking exhaust catalyst (CAT) and engine failure.

Revo Performance ECU Software for the TTRS & RS3 not only utilises the factory safety functions but actually improves them. You can rest assured that your vehicle is able to take all you can throw at it with integrated features exclusive to Revo ECU Software including Cold Start Protection and Temperature Protection which actively monitor oil, intake (IAT) and exhaust temperatures (EGT) and reduce power if they get too high. There’s even an oil temperature based rev limiter should you get heavy footed before the engine oil has sufficiently warmed up.

It all started in late May 2017 in Surberg, Germany when Revos calibration team got their hands on the latest Audi 5 cylinder engine, labelled DAZA by Audi. By travelling to Germany, Revo was able to get a head start on the re-engineering of this platform and get a feel for the potential of this as a performance package going forwards. Based on this initial assessment, Revo ordered their own 8S TTRS whilst continuing development through the Global Development Programme.

Over a year in development, covering over 25,000 miles globally on both the RS3 and TTRS which share the 2.5TFSI engine, testing was carried out on 3 vehicles in the UK and 12 vehicles in 6 continents. Involving vehicles in Germany, Croatia, Malta, Australia, Peru, Russia, South Africa, China, Brazil and Mexico, Only Revo operate a Global Development Programme through their network of over 400 Revo Authorised Dealers worldwide. Access to vehicles on this scale enables the calibration team to fine-tune products before release, testing products in a wide range of climatic conditions including at altitude, with varying fuel quality and increased humidity. This also allows Revo to test how the Software performs in different driving scenarios including the drag-strip, track and sprint racing and of course, daily driving.
