Sabre Stage 3 ECU Software – Focus RS MK3

The Focus RS MK3 takes the RS marque back to 4WD giving exceptional point to point drivability and performance. This is a very modern 4WD system with sophisticated torque vectoring and a true driver’s car sticking with manual shifting to ensure a directly engaging drive.

Part of what makes the RS so engaging is the very fast response from the factory twin scroll turbo. For a fast road car, most owners enjoy a wide powerband with minimal turbo lag so it was very important for Sabre to retain this profile when developing the Stage 3 upgrade. While there are options for aftermarket turbo upgrades like the NX2, the ensuing turbo lag and loss of low end torque can be very disappointing for many owners. This was the key element to developing the Sabre Stage 3 with over 12 months testing and refining the 500RSX turbo upgrade.

For all other turbo options please look at Sabre Stage 4 mapping

Options for normal 95 octane fuels are available with around a 5-10% reduction in performance compared to 97-99 octane.

Recommended Hardware
The Sabre Stage 3 requires typical bolt on upgrades as a starting platform. The key upgrade is the Sabre 500RSX turbo which is a direct fit to existing hardware. If you do not wish to build your engine (forged engine) then we can limit power to circa 440-450bhp on a good fuel.  For built engines we can expect to see 460-470bhp with standard cams with a HPFP upgrade. For power up to 500-520 we recommend Stage 3 cams + spring kit and/or water/meth injection.

Purchase information
Sabre ECU software upgrades have been developed under many conditions and cars. This process allows us to assess the tuning long term according to specification and variations, not just from a single vehicle.

Optimal performance and drivability will be achieved where typical hardware, conditions and fuel octane are used. Underlying and existing faults should be rectified before installing performance software. Please refer to the Terms & Conditions for more information.
