COBB Accessport ECU Tuners & Performance Devices

Your Toyota's ECU, the computer that controls how your engine and transmission behave, ships with a conservative factory tune that leaves real power and drivability on the table. The COBB Accessport V3 gets it back. It's the industry-leading handheld tuner, and it flashes your ECU right through the OBD2 port, no tools, no cutting. The result is sharper throttle response, stronger power delivery, and smoother, more predictable shifting.

Every Accessport we sell is genuine COBB hardware, built for the new-generation turbo Toyotas like the 4th Gen Tacoma, 6th Gen 4Runner, and the 2.4L i-FORCE and i-FORCE MAX engines. As an authorized COBB dealer and OTT (Overland Tailor Tuning) retailer, we can load custom OTT calibrations dialed in for how you actually drive.
