2025+ Toyota 4Runner i-FORCE 2.4T Stock vs Tuned
The COBB Tuning Accessport is the industry’s most popular and versatile ECU tuning device, giving Toyota owners an easy and reliable way to unlock real performance gains. By replacing the factory’s conservative calibration with refined, performance-oriented tuning, you can access power and drivability the stock setup leaves on the table. Choose from pre-loaded Off-The-Shelf (OTS) maps that follow a proven upgrade progression, or run custom calibrations tailored to your specific modifications. This is the only engine management tool most drivers will ever need.
This version of the Accessport also supports TCM flashing. The TCM (Transmission Control Module) manages all transmission behavior, and with included OTS transmission maps you can fine-tune shift schedules, shift firmness, torque limits, and skip-shift characteristics to better match your driving preferences.
Included with this Accessport is a Gateway Bypass Harness. This harness connects between your vehicle’s OBD-II port, the Gateway module, and the Accessport itself. It allows the Accessport to communicate with the ECU in situations where the vehicle would normally block access—such as initial setup, unsupported ROM extraction, or recovering from an interrupted flash. The bypass harness is not required for normal map switching or uninstall procedures.
Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support if you have any questions.
