mountune Optimized Accessport Calibration Upgrade


This product is for pre-existing Accessport users that did not purchase their Accessport directly from Mountune.
This is non-transferable.

This is for tuning only and does not include the Accessport.

Renew and maximize the performance of your Focus RS, Focus ST, and Fiesta ST.
If you've decided you want to explore the different fuel types that we support, or if you've changed your entire list of modifications and need to start with a clean slate, we've got you covered. Mountune can optimize your performance with a new custom calibration via data logging analysis and program revisions for the Focus RS, Focus ST, and Fiesta ST.

The mountune Optimized Accessport Calibration is built to your specifications based on your modifications, octane, and preferences / requirements. mountune optimized calibrations go beyond the standard OTS files included with the Accessport. Engine performance is optimized 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 is 45 days from the time the first file is sent to the customer. Multiple calibrations can also be requested during this time period for the selected fuel type and/or octane. 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.

Please note this offer is not available for turbocharger upgrades, engine swaps, nitrous oxide applications and applies to the original purchaser only. This service is nontransferable and other restrictions may apply.

This part has been designed and is intended for off-highway application only. Installation of this part on a vehicle that is driven on public roads may violate U.S. and Canadian laws and regulations relating to emission requirements and motor vehicle safety standards.

5 of 5 Amazing Tune December 15, 2019
Reviewer: Dan from Albuquerque, NM  
I was running the stock Cobb tune on my RS for a while and finally decided to get a custom one done with Randy. What a difference! The performance increase is very noticeable even with just an upgraded FMIC. I've heard good things about Randy and I can now confirm that he is a true professional as he worked with me throughout the whole process. Highly recommended!

5 of 5 Updated Tune from Randy August 2, 2019
Reviewer: John Dee from Killeen, TX  
Purchased an updated Tune for my Focus RS due to the installation of a WGA and intercooler. As always Randy is 100% professional and the results are fantastic! Couldn't be happier with the tune!
