These adjustments include changing map slots, turning custom traction control on/off and adjusting the amount of slip the custom traction control enables. Also, automatic vehicles can now take advantage of new features that include a bump box, burnout mode, transbrake and 2-step. These adjustments can be found under “Tune” -> “Adjustments” -> then select which new feature you’d like to adjust. It’s important to note that the CCF Accessport Adjustment are dependent on the calibration file being used.

The heart of the Cobb Stage One Power Pack is going to be the access port tuner. This is an all-in-one tool for your 2015 Echo Boost Mustang. It's going to allow you to do data logging, allow you to clear and read trouble codes, and best of all, allow you to load the Cobb Performance Maps that are designed to increase the horsepower and torque of your Echo Boost Mustang. This unit is going to come preloaded with maps specifically for use with the high-flow filter that's included.
Cobb also provides a magnetic bracket that'll stick to your dashboard, the cables necessary for hook up, two different face plates, a carrying case, and like I said, a pre-oiled filter that's ready to be installed in your car. The Stage One Power Pack is a great way to add some horsepower to your 2015 Echo Boost Mustang.
The access port can also be updated so future maps can be loaded for future modifications.
