Take complete control of your 2021-2022 Ford F-150 3.5L EcoBoost or Tremor with the COBB Tuning Accessport V3 AP3-FOR-011 - the most advanced ECU and TCM tuning solution available for this platform. Designed by COBB Tuning, a proven leader in performance calibration, this handheld tuner unlocks power, torque, and drivability that the factory calibration leaves on the table.
The Accessport V3 replaces conservative factory engine and transmission strategies with optimized calibrations that improve throttle response, torque delivery, and overall performance throughout the RPM range. Featuring a large, full-color high-resolution display with fully customizable gauge layouts, the Accessport allows you to monitor up to six live parameters at once, log data, and measure real-world performance metrics such as 0–60 mph and quarter-mile times.
Installation is straightforward and plug-and-play through the OBD-II port. Select from preloaded Off-The-Shelf (OTS) maps developed by COBB or return the vehicle to the stock tune at any time. With full engine and transmission tuning support, the AP3-FOR-011 lets you tailor shift behavior, throttle mapping, torque management, and fuel delivery to match your driving needs — whether daily driving, towing, or maximum performance.
Whether you are hauling heavy loads, towing a trailer, or simply want a more responsive and powerful truck, the COBB Accessport V3 delivers a level of control and flexibility that no other tuning solution offers for the F-150 3.5L EcoBoost platform.
