Revo performance software is developed to enhance the driveability of your vehicle, giving access to more power and torque throughout the rev range while maintaining the extensive factory safety mechanisms. Although Revo offers some of the most substantial performance gains available, peak figures don't give a true indication of vehicle performance and are never the sole focus during development. Revo software offers a perfect balance of performance, economy, longevity and safety.


The 3 cylinder turbocharged 1.5 EcoBoost engine in the Ford Fiesta ST MK8 is smaller than the MK7 but packs even more of a punch. The ST's impressive low-down grunt and more responsive turbo offer great performance and a lot of potential for those driven to experience its true potential. Close monitoring of the GPF system has been an essential step in finding the limitations and tuning potential of the engines. The consensus is that the GPF not only mutes but limits the engine power, Revo ECU calibration might offer a reason to dispute that. 

Enhancing the vehicle with Revo ECU Software gives you much more than just an increase in power and torque. A large part of development is based on drive cycle and driver feedback.  Our calibration doesn’t just give a great dyno curve and peak power/torque figures but also delivers in feel; giving a smoother yet more responsive feel at low RPM/ partial throttle. Along with huge gains at wide-open throttle throughout the whole rev range.  

Only Revo performance ECU Software maintains factory safety levels and additional driving features. You can switch between three pre-set fuel quality modes depending on the fuel you use; these modes are set through testing our development vehicles in varying climatic conditions with a range of fuel qualities throughout the world. The Revo SPS Software Switch is also available separately and can be used to quickly switch between performance modes and access the additional Anti-Theft mode. 


Rather than simply removing the GPF, and therefore making vehicles illegal for road use, we have been monitoring the effects that running higher power has on them. Our Stage 2 GPF software retains the stock downpipe, factory catalytic convertor and GPF 3, although we did upgrade the GPF back section on our own ST development vehicle to give more exhaust acoustics.  
Whilst we are not supporting GPF removal, over months of extensive development, we tested all variations of exhaust setups to determine the effects and restrictions of the stock downpipe and GPF. Although an exhaust system with no Catalytic convertor or GPF is always going to be slightly less restrictive than a stock system, we saw less than a 4% difference through a limited part of the rev range with little change elsewhere. There is a much more significant restriction closer to the engine; a combination of the integral manifold/port/turbine design. 
All Revo Stage 2 GPF software is specifically designed for a Stock downpipe and GPF. Removal of these parts whilst running Revo software may result in running issues and an engine management warning light. 


Software Features



Switchable software for 3 performance modes and Antitheft.1


Boost is limited until safe oil temperature is reached.


Enhanced engine cooling and oil temperature management.


The top speed limit for this vehicle has been removed.


Enhanced exhaust note on overrun in Sports Mode.


RPM Limit has been increased to 7000rpm for optimal performance. Also allows 60mph in 2nd gear.



Only Revo operates a Global Development Programme through its 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 climates and conditions including altitude, fuel quality, humidity. This also allows Revo to test how Revo products perform in different driving scenarios and formed a vital part in the development of Performance ECU Software. You can read more information on GPF on our blog. 


Dyno Graph @Hubs

Ford Fiesta ST MK8 Stage 2 Dyno




For engine oil to work effectively and lubricate your engine it needs time to warm up. When you first start your car, the cold oil is at its thickest, producing higher oil pressure when pumped around the engine putting extra pressure on oil seals. As the engine temperature increases, so do oil temperatures. This thins the oil, enabling it to run more freely and better lubricate the moving parts of your engine. Cold Start Protection helps protect engine components by limiting turbo boost based on RPM and oil temperature until it reaches the 80ºC optimum operating level. 


Exhaust gas temperatures (EGT) are also monitored, adapting the operating conditions (Air Fuel Ratio) to ensure they stay within safe parameters. If EGT's reach a set upper limit, then power is automatically reduced until the engine returns to a safe operating temperature. 


The ST already comes with exhaust overrun through its Active Value Exhaust. This has been enhanced by Revo offering a variation in acoustics both in sports and track modes. The duration of the overrun has been increased over Stage 1 software.  



Using an SPS switch you can take advantage of the switch-ability of Revo software. The Patented OBD2 interface is the ultimate compliment to Revo performance software, giving you the ability to switch between 3 fuel quality modes and an Antitheft mode via the vehicle OBD port.

  • SPS Position 1 – Antitheft Mode
  • SPS Position 2 – 95ron Performance Mode
  • SPS Position 3 – 97ron Performance Mode
  • SPS Position 4 – 98/99ron or 100ron Performance Mode (an option when installed) 

Simply select a program, plugin, wait a few seconds, remove the SPS device and start the car. It's simple and there's no fixed switch to install in the vehicle.


As well as the fuel quality modes, Revo software is installed with built-in Antitheft Mode. Once the vehicle is put into this mode via the SPS device the engine revs will drop and throttle response will be disabled. The low revs mean the car will struggle to be moved even on the clutch without stalling. Adding an extra level of security to your vehicle. Switch it back to a performance mode and enjoy the drive.
