The mountune Focus RS B upgrade package includes the very best components to enhance and optimize the performance of your Focus RS including custom ECU calibration to optimize the performance of your car based on your specific use and build specification. mountune performance calibrations are proven to extract the maximum reliable performance and the mountune B series upgrade packages bring together the essential pieces to get you going.

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 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 RS tuning experience than any other source available to you. Choose from one of the many upgrade packages to enhance your Focus RS.

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 RS 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)

Maximize the performance of your Focus RS

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
  • Auto Start / Stop disabling
  • Launch Control settings**
  • Flat Foot Shifting settings**
  • Ethanol (E30 & E40) support
  • 100+ Octane support
  • Gear Based Torque Limiting
  • Shift Assist settings
  • Exhaust burble settings
  • Exhaust valve settings
  • Idle Adjustment
  • Rev Limiters

Worth Every Penny June 23, 2018
Reviewer: Darren from Leduc, AB Canada  
I decided to bite the bullet and pick up the B7 package from Mountune.  Even though i'm in Canada, the parts didn't take long to arrive.  Upon opening the boxes, I found myself impressed by the packaging - everything was individually wrapped with no chance of damage from shipping.  

The install was pretty straight forward as well.  Everything fit like a glove; I had 0 issues with fitment.  The only tricky part was the intercooler.  If I had one suggestion to make, T-Clamps would have made things easier on certain parts (specifically for connection to the throttle body).

The instructions I received from Mountune for installing and setting up the AccessPort were very thorough, and easy to follow.  Data logging has been a breeze so far.

After switching to the Mountune MAP, results were instantly noticeable.  The car builds boost so fast, and the torque is much more fluid than on stock.

I highly recommend this package to anyone looking to improve the performance of their RS.

Reviewer: Seattle 2017 RS Owner from Seattle, WA United States  
Package is fantastic.  This is first experience with intake/tune upgrades to ford platform vehicle.  I've previously done similar work/tuning on VW vehicles and really come to expect more turbo/boost excitement than what stock vehicles provide.   The resulting power and torque gains are dramatic and put a big grin on my face  during both daily driving and more enthusiastic outings with the car.  Under normal throttle the car feels stock, but with a little juice in the 2500-5500 rpm band the machine comes to life... absolutely recommend.
