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
Maximize the performance of your Focus RS
- Slot 4 - Same as Slot 1 with LESS spark (aka panic mode / bad fuel mode)
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
