Mountune Optimized Calibration (Tuning)

We rely on the industry’s best tuning/flashing device, the COBB Accessport, to deliver our proven ECU calibrations. The Accessport coupled with mountune’s custom performance calibration unlocks power hidden within the factory ECU calibration by replacing conservative factory settings with more aggressive calibrations. The COBB Accessport from Mountune USA includes all of the standard COBB OTS (off the shelf) calibrations along with a custom Mountune calibration* built to your specifications based on your modifications, octane, and preferences. The results are impressive gains in torque and horsepower with incredible custom features that can be adjusted to meet your requirements. Our team has spent countless hours on the dyno and track developing performance upgrades that perform in a wide range of applications. With over 30 years of Ford 4 cylinder ECU calibration experience, it's no surprise that Mountune USA are partners with Team O'Neil Motorsports, LaRoza Racing, and O.D.D. Racing. And with multiple Rally America Championships won using Mountune USA custom calibrations, our programming team has more Focus RS tuning experience than any other source available to you. Choose from one of the many upgrade packages to enhance your Focus RS. The Accessport from Mountune is not locked and can be further adjusted at any time.

The Mountune calibrations include 4 slots that are switchable at any time, on the fly, by simply pushing a few buttons. This is a very convenient feature that can be further adjusted in many cases.
