Unlock hidden power, refined control, and comprehensive engine and transmission management with the COBB Tuning Accessport V3 AP3-FOR-012, the premier ECU and TCM tuning solution for the 2020–2024 Ford Explorer ST. Developed by COBB Tuning, a long-standing leader in automotive performance calibration, this advanced handheld tuner transforms how your Explorer ST accelerates, shifts, and responds—without permanent modifications or complicated installation.
The Accessport V3 delivers professional-grade tuning through a simple plug-and-play interface. Once connected through the OBD-II port, you gain access to preloaded Off-The-Shelf (OTS) tuning maps engineered specifically for the Explorer ST platform. The large, full-color, high-resolution display allows you to monitor up to six engine and vehicle parameters simultaneously, including boost pressure, engine load, temperatures, ignition timing, and torque output.
Unlike basic flash tools, the AP3-FOR-012 provides full control over both engine and transmission behavior. This includes optimized fuel and ignition strategies, improved throttle response, refined shift scheduling, enhanced torque management, and smoother power delivery. Drivers can tailor the vehicle for daily commuting, spirited driving, or performance-focused setups while maintaining factory safety strategies.
Additional COBB Custom Features such as Auto Start-Stop Disable, Dynamic Pedal Control, Valet Mode, and Tire Size Adjustment further enhance drivability and personalization. With the ability to restore the factory tune at any time, the Accessport V3 offers flexibility, confidence, and long-term value for Explorer ST owners seeking a smarter and more powerful driving experience.
The COBB Accessport V3 is designed to increase both horsepower and torque by replacing conservative factory tuning with optimized performance calibrations. Gains vary based on fuel quality and conditions, but Stage 1 Off-The-Shelf maps provide measurable improvements in overall engine output and throttle response.
These gains translate into stronger acceleration, improved mid-range torque, and a noticeably more responsive driving experience compared to the factory calibration.
The AP3-FOR-012 Accessport V3 is specifically designed for the 2020–2024 Ford Explorer ST equipped with the 3.0L EcoBoost engine. It is not compatible with non-ST Explorer models.
No, you do not need to send your ECU to Cobb to be unlocked if you own a 20-24 Ford Explorer ST.
Yes. The Accessport V3 can function as a high-level monitoring and data-logging device even if a performance tune is not installed.
When used with approved Off-The-Shelf maps and according to application guidelines, the Accessport is emissions compliant and legal for street use in all 50 states.
Any ECU modification may impact factory warranty coverage. The Accessport allows the factory tune to be restored at any time, but warranty decisions are determined by the vehicle manufacturer.
Installation is simple and fully reversible. The Accessport connects through the OBD-II port and provides step-by-step on-screen instructions. No cutting, wiring, or permanent modifications are required.
COBB Tuning provides a limited warranty covering manufacturing defects when the product is purchased from an authorized dealer. Warranty coverage requires proof of purchase and proper use according to COBB guidelines. Return and warranty eligibility may vary by retailer.
