R35 Cobb AccessPORT with TCM

The AccessPORT by Cobb Tuning is the industry leading OEM ECU flashing, managing and monitoring assistant. The ECU in your GT-R leaves the factory with conservative settings, to make sure the car performs well under all conditions. There is a lot of room for performance improvements.

You can unlock power hidden within the ECU by replacing conservative factory settings with more aggressive calibrations. The result is impressive gains in torque and horsepower while maintaining a high degree of safety.

The AccessPORT comes with pre-installed maps that are configured for a stock GT-R. If you want more power, we can design a complete custom map using our powerful AccessPRO software. This is done through what we call a "Remote Tuning Session". About 80% of our customers who purchase the Cobb AccessPORT choose this option. The Remote Tuning Session optimizes your GT-R's power for your exact GT-R. Common gains above the standard pre-installed AccessPORT maps are 30-60+hp with the Remote Tuning Session option.
