Cobb 2025 Toyota 4Runner AccessPort - AP3-TOY-002

The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Toyota. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow COBB's staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It's the last engine management solution you'll ever need.

This version of the Accessport includes the capability to flash the TCM which is the unit that controls the transmission. It includes various Off The Shelf transmission tunes which adjust shift points, shift firmness, skip shift behaviour, and torque limits to fit your preferred driving style.

This Accessport includes a Gateway Bypass Harness. To use it, connect the harness to your vehicle's OBD-II port, the Gateway connector, and then to the Accessport. The Gateway Bypass Harness enables ECU communication in situations where the Accessport would otherwise be ignored, such as during initial installation, when dumping an unsupported vehicle ROM file, or when recovering from a failed flash.

It is not required for map changes or uninstalling the Accessport.

Warning. Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure.

Why?

The in-cabin mountable Accessport V3 has a large, full colour, high resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colours), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included, with enough space for 100 calibrations. This is your new Accessport, and maybe the last one you'll ever need.
