mountune Optimized Accessport Calibration

Renew and maximize the performance of your Focus RS, Focus ST, and Fiesta ST.

If you've gone beyond our program revision period, 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. For an additional $279.00 fee, mountune Accessport customers can obtain optimized 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.
