Product Description

The Ford Focus is now on its 4th generation and comes equipped with the 2.3L EcoBoost engine. This 280PS variant is derived from the one used in the Mustang and previous model RS. Out of the box it offers 420NM and it's definitely much punchier compared to the MK3 ST with its 2.0L EcoBoost engine.

However, as with the MK2 and MK3 ST, we knew that once our team of in-house calibration engineers got their hands on it, there would be significant improvements. And we weren’t wrong. After thousands of miles and many months of development, you won’t be disappointed with the performance increases and features that we have been able to produce with our Stage 1 ECU software.

The perfect balance of performance and driveability 

Revo offers some of the most substantial performance increases on the market, however, only the driven know that peak figures form part of a much bigger picture and are never the sole focus during Revo’s development process; it’s all about the drive. Only Revo offers a perfect balance of performance, economy and engine longevity.

A large part of development is based on driving scenarios and feedback; our calibration doesn’t just offer great dyno curves and peak power/torque figures but an exhilarating driving experience. Expect smooth and refined response at low RPM & partial throttle, with huge gains at wide-open throttle and throughout the whole rev range.

Software Features

Enhanced protection based on Oil, Air and Coolant temperatures.


Speed Limit Unlock 

The top speed limit for this vehicle has been raised.


Exhaust Overrun 

Enhanced exhaust note on overrun in Sports & Track Modes.


Adaptive Software 

Use 95-102Ron Fuel.

Global Development Programme 

Only Revo operates 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 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.

Get far more than a peak power figure 

The Revo tuning philosophy ensures that impressive performance benefits are balanced with useable, reliable power delivery that enhances the way you can drive your vehicle. Development on the road and racetrack as well as testing in controlled dyno conditions gives you a clearer picture of the performance you can expect from Revo ECU Software. Testing in this way plays an important role in ensuring the highest quality products and delivering the driving experience expected.

Additional Features 

Temperature Protection 

Revo Temperature Protection is an array of additional safety features that manage vehicle temperatures and help with vehicle longevity and performance by closely monitoring air, coolant, and oil.

These vehicles can start to struggle with heat management during certain driving scenarios. Therefore the grill shutters parameters have been enhanced to allow the shutters to open sooner and increase the airflow over the intercooler. To gain better control of the coolant temperatures the routine for the Radiator fan has been increased to allow it to now run faster when required. In addition, the setpoint for the oil temperature has been set lower to allow the system to aid in maintaining lower temps. 

Adaptable Software 

Maintaining full factory knock control, our calibration engineers have extensively tested varying fuel qualities. This means that adaption within the ECU and Revo software will allow you to use 95-102ron fuel on the same Stage 1 calibration. However, for the optimal balance of performance and driveability, we would recommend using 99ron fuel wherever possible.

Exhaust Overrun 

The ST already comes with exhaust overrun. This has been enhanced by Revo offering a slight variation in acoustics both in sports and track modes.
