COBB Accessport V3 Mustang EcoBoost 2015-2023

COBB’s Accessport V3 is the best tuning option available for your 2015-2023 EcoBoost Mustang. This flexible ECU upgrade solution unlocks power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. The Accessport V3 (P/N: AP3-FOR-003) can provide off-the-shelf calibrations for most bolt-on modifications and it should be the last engine management solution you will ever need. Along with all the new viewable upgrades from the V2, the V3 also has more speed, more memory, more map storage, more live gauges, and more troubleshooting help.

Choose from multiple gauge setups which include your choice of one gauge to six gauges. Scroll through tons of different display parameters to view the specific information important to you. Information can be displayed in metric or imperial units. A shift light can be set to the desired RPM and is plenty bright that a separate shift light isn’t needed. Monitor all the parameters you want to view and customize each layout for the street, strip, or track.

The most important aspect of the Accessport V3 is the ability to install different maps and quickly adjust tuning elements such as idle, timing, launch control and flat-foot shifting.

Data logging is included so you can view engine vitals which can alert you to any changes that need to be made to your tune. If self-tuning isn’t your thing, visit a local tuner in the COBB Professional Tuning Network to have a custom tune created and loaded onto your Accessport V3. You don’t even need to physically visit a tuner if you don’t want to. Use easy data logging and map loading on your Accessport V3 to have an e-tuning expert remotely custom tune your vehicle.

Tech Tip: Several COBB Custom Features (CCF) are now user adjustable through the Accessport for the EcoBoost mustang. 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. For example, the Traction Control feature must be enabled via a custom tune (Custom Tune is NOT Included).

*To ensure your COBB Accessport has all of the available features listed, please make sure to check for the latest firmware release.

Installation is extremely simple, fast and straight forward with easy-to-understand directions to guide you through setup. Initial setup matches the Accessport V3 to your vehicle modifications.
