Wake Up Your Bronco's 2.7L EcoBoost — No Wrenches Required
The COBB Accessport V3 is the world's best-selling, most flexible ECU upgrade for Ford. For the 2021+ Ford Bronco 2.7L EcoBoost, it replaces Ford's conservative factory calibration with COBB's Off-The-Shelf maps to deliver noticeable power and torque gains, sharper throttle response, and reduced turbo lag — all through the OBD-II port in minutes. Uninstall is just as easy: a single menu selection returns the ECU to exact factory state.
The Accessport mounts in-cabin, taps your vehicle's data bus, and gives you a full-color gauge display for boost, throttle, and up to six live parameters at once. Data logging stores up to 10 hours of engine data for tuner review, and you can store up to 100 calibrations to switch between maps instantly.
⚠️ Fitment — 2.7L EcoBoost V6 ONLY. This Accessport is for the 2021-2026 Ford Bronco 2.7L EcoBoost. It will NOT work on the 2.3L EcoBoost 4-cylinder Bronco, or on the Bronco Raptor (3.0L). Verify your engine before ordering.

Included Gateway Bypass Harness
Every Accessport ships with the Gateway Bypass Harness. It bridges your OBD-II port, the Gateway connector, and the Accessport for initial ECU communication and ROM recovery. Once you're mapped, you only need it for recovery — never for day-to-day map changes.
Gateway Bypass Harness
Included. Connect the harness between your OBD-II port, the Gateway connector, and the Accessport. Required for initial ECU communication, ROM dump on unsupported files, or flash recovery. Not needed for normal map changes or uninstall.
50-State Legal
The Accessport is 50-state legal when installed per COBB's application guide for your vehicle — street legal in all 50 states, including California.
Emissions
50-state legal when used per COBB's application guide for your vehicle. Legal for sale and use on emissions-controlled vehicles in all 50 states when installed as directed.
Warning: Installing this Accessport over anything other than OEM or COBB software may result in ECU/TCM failure. Designed to tune stock, unmodified ECUs only.
Fitment

Related COBB Accessport Tuners
Have a different Bronco? Here's the matching Accessport for the other model:
Will this work on my 2.3L Bronco? No — this Accessport is specific to the 2.7L EcoBoost V6. The 2.3L 4-cylinder requires a different part number.
Can I return my Bronco to stock? Yes — the Accessport includes an Uninstall option from the main menu that reverts the ECU to exactly the factory calibration. You can also resell the Accessport after uninstalling.
Do I need a custom tune, or will the included maps work? The pre-loaded Off-The-Shelf (OTS) maps work great for stock or lightly modified Broncos on 87, 91, or 93 octane. Custom maps are available through COBB-licensed tuners for heavily modified builds.
What is the Gateway Bypass Harness for? It lets the Accessport communicate with the ECU during initial installation and ROM recovery. After install, you only need it for recovery situations — not for everyday map switching.
