The ZERONINE DESIGN Stage 01 power upgrade for the Mk3 Focus ST 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.
THE POWER’S IN YOUR HANDS
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.
There's also the addition of an immobiliser calibration which as the name suggests prevents the vehicle from being started and driven when enabled.
INCLUDED WITH STAGE 01
• ZERONINE DESIGN performance calibration, standard calibration and immobiliser calibration (downloaded to phone / tablet after purchase)
