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 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. With over 15 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 Fiesta ST tuning experience than any other source available to you.
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 Fiesta ST are laid out as such:
- Slot 1 - Standard high performance calibration
- Slot 2 - Standard high performance calibration with indicated Launch Control
- Slot 3 - Low boost performance calibration
- Slot 4 - Same as Slot 1 with LESS spark (aka panic mode / bad fuel mode)
Maximize the performance of your Fiesta ST
For those who require additional support, the mountune ECU calibration can be optimized further with data logging and program revisions at no extra charge. Engine performance is enhanced by reviewing data logging files along with calibration revisions based on feedback from the end user. The duration of the calibration and file revision period for the chosen fuel type / octane is 45 days from the time the first file is sent to the customer, which is preloaded onto the AP when it ships. Multiple calibrations can also be requested during this time period. Once the 45 day period has expired the custom calibration period ends. Future custom calibrations are subject to additional fees depending on the exact nature of the request. mountune optimized Accessport calibrations are available only to customers that have purchased the Cobb Accessport directly from mountune. Custom programming options include, but are not limited to: MAP (slot) switching, Launch Control settings, Flat Foot Shifting settings, Ethanol (E30 & E40) support, 100+ Octane support, Gear Based Torque Limiting, Shift Assist, Idle Adjustment, Rev Limiters, Shift Light settings, and Advanced Wastegate Adjustments. *Please note this free offer for calibration optimization is not available for turbocharger upgrades, engine swaps, or nitrous oxide applications and applies to the original purchaser only. This service is nontransferable and other restrictions may apply. If you have questions about our mountune calibrations please do not hesitate to contact us directly at (714) 424-9400 or at
