Cobb 24-25 Toyota Tacoma MT/AT AccessPort

The Accessport is the world’s best-selling, most versatile, and user-friendly ECU tuning solution for your Toyota. Unlock hidden power by replacing factory-conservative settings with more performance-oriented calibrations. Follow a proven staged upgrade path using pre-loaded Off The Shelf (OTS) maps, or take complete control with custom tuning for any modification level. The Accessport is the ultimate engine management tool—built to evolve with your vehicle. This version of the Accessport also provides the ability to flash the Transmission Control Module (TCM). Off The Shelf transmission maps are included, offering refined control over shift points, firmness, skip-shift behavior, and torque limits. Tailor your driving experience to your style—whether that’s smooth daily comfort or precise, aggressive performance. Included with this kit is the Gateway Bypass Harness. Simply connect it between your vehicle’s OBD-II port, the Gateway connector, and the Accessport. This harness enables ECU communication in specific scenarios where the Accessport would otherwise be blocked—such as during initial setup, unsupported ROM extraction, or recovery from a failed flash. It’s not required for everyday map changes or uninstalling the Accessport.
