The mountune Focus ST B1 upgrade package includes the very best components to enhance the performance of your Focus ST including custom calibration to optimize the performance of your car based on your specific use and build spec. mountune performance calibrations are proven to extract the maximum performance from the Focus ST and the mountune B1 package brings together the essential pieces to get you going.

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 Focus 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 Focus 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 Focus 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 out. Multiple calibrations can also be requested during this time period. Once the 45 day period has expired the free 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 who have purchased the Cobb Accessport directly from mountune.

Custom programming options include, but are not limited to:

  • On-the-Fly MAP (slot) switching
  • Launch Control settings
  • Flat Foot Shifting settings
  • Ethanol (E30 & E40) support
  • 100+ Octane support
  • Gear Based Torque Limiting
  • Shift Assist settings
  • Burn Out Mode
  • Idle Adjustment
  • Rev Limiters
  • Speed Limiters
  • Shift Light settings
  • Advanced Wastegate Adjustments
  • Low Traction / Wet Weather settings

*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 non-transferable and other restrictions may apply. Some custom options are only available on vehicles equipped with manual transmissions.

Awesome! August 16, 2017
Reviewer: Kevin Franklin from Louisville, KY United States  
I installed the package this past weekend and the quality or each item is exceptional! Having previously installed the exhaust system and aluminum intake, the addition of this package was a addition. As others have stated, this is how the Focus ST should feel. Well down Mountune.

Unmuzzled Power June 6, 2017
Reviewer: Daniel Baker from Apache Junction, AZ United States  
From the factory, the Focus ST has always been a fun, fast, and great handling car. I've always felt the car has felt a bit muzzled though with the stock tuning. Since installing the wonderfully solid Mountune intercooler and tune, it is like driving a whole new car. The power is right there when you want and need it all the way through redline. Working with Randy to square away the tune has be painless. I wish response time was a little quicker, but I can understand how busy it might be. All in all, a wonderful way to get more out of the Focus ST.

It's a new car February 18, 2017
Reviewer: ARN from PHOENIX  
This is a fantastic base package to build upon. The intercooler is beautiful and very well constructed. It is a major improvement over the OEM part. I was so happy with the feel of the car after installation. I could really tell the improvement in power before I installed the accessport. It felt like my engine grew. The air filter is far superior to the stock paper filter. The new filter breathes so much better than the stock filter and I think I heard my engine thank me when I started her up after installing. The gains in torque achieved from the accessport really complete the package. Overall, I am extremely satisfied I chose this package. I am very happy with all of the products. Mountune’s quality is top notch and the upgrade in performance is quite impressive.

Quality intercooler and tunes September 18, 2016
Reviewer: Michael Bunker from New Lisbon, WI United States  
Amazing how much the 91 tune woke up my car. Intercooler is kind of time consuming to install but is just like factory fit that's why I went with it !
