The Accessport is the industry leading OEM ECU flashing, managing and monitoring assistant. Unlock power hidden within the ECU by replacing conservative factory settings with more aggressive calibrations. The standard Cobb Accessport from mountune USA includes all of the standard Cobb calibrations and can also be ordered with an optional race only, Optimized mountune calibration. The results are impressive gains in torque and horsepower.
With over 20 years of Ford 4 cylinder ECU calibration experience it's no surprise that mountune USA are partners with leading race and rally teams across the globe. This Accessport is not locked and can be further adjusted at any time.
Optional Race Only Mountune Performance calibration slot assignments
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. The default settings for the Focus ST and Fiesta ST are laid out as such:
- Slot 1 - Standard high performance calibration
- Slot 2 - Standard high performance calibration with indicated Launch Control and Flat Foot Shifting
- Slot 3 - Low boost performance calibration
- Slot 4 - Same as Slot 1 with LESS spark (aka panic mode / bad fuel mode)
**Launch control & flat foot shifting can be adjusted anytime via the Accessport. By default launch control is set at 2400 RPM and flat foot shifting is set at 4000 RPM.
