The ZERONINE DESIGN Stage 01 power upgrade for the Mk3 Focus RS provides a substantial uplift in both power and torque across the entire rev-range, adds a host of new functionality and improves outright performance, drivability and overall driving enjoyment.
As with all ZERONINE DESIGN upgrades, every product has to pass our own stringent durability testing, which includes thousands of both track and road-mile accumulation whilst monitoring key powertrain and drivetrain parameters. When it comes to performance calibrations, we have decades of experience at both OE and the highest level of motorsport under our belts, so you can be assured that regardless of how you drive your car, or what octane fuel you want to use, a ZERONINE DESIGN calibration will deliver OE-like drivability with robust, reliable performance, lap-after-lap, mile after mile.
Quite literally in this case, as the ZERONINE DESIGN FLASHlink upgrade allows you to easily DIY install and update calibrations to your ECU using nothing more than our app, the supplied Bluetooth OBD interface and your Smartphone; no laptop, cables or handset required.
The latest version of FLASHlink also provides additional functionality allowing you to select configurable gauge displays using the OBD data-stream, carry out comprehensive data-logging and there's also a built-in performance meter for good measure.
Focus RS owners also benefit from additional functionality as part of the Stage 01 calibration that take your enjoyment to new-found levels; these include the ability to enable (from the steering wheel) downshift blip - to help rev-match on downshifts, no-lift shift functionality - for faster gear changes and also, owner configurable rpm values (set via the app) for launch control - where you can choose the revs you wish to use when launch control is active.
There's also the addition of an immobiliser calibration which as the name suggests prevents the vehicle from being started and driven when enabled.
