Stage 2: +12% to 15% Gains in HP and TQ

 The new GT-R AccessPORT with TCM support is the industry's first OEM ECU and TCM flashing, managing and monitoring assistant. Unlock power hidden within the ECU by replacing conservative factory settings with more aggressive calibrations. Upgrade the factory Launch Control logic and enable Run Clutch Gear Learning, Clutch Touch Point and Clutch Capacity adjustments. The result is impressive gains in torque and horsepower with improved transmission responsiveness and driveability, all while maintaining a high degree of safety. The AccessPORT comes with pre-installed ECU and TCM maps that are optimized for common performance modifications.

Tuning flexibility ranges from simply loading one of the included performance maps designed for common modifications, all the way to complete custom map authoring using our powerful AccessTUNER software. Extract maximum power from virtually any modification while retaining the driveability and sophistication inherent in the OEM ECU.

NOTE: The maps currently available for AccessPORT with TCM support are designed for vehicles with stock transmission clutch packs. These maps have not been tested with aftermarket clutch packs and may result in unsatisfactory performance and wear. A custom tuned TCM map from your favorite Pro Tuner may be required for optimal performance with aftermarket clutch packs.

NEW AccessPORT ECU Flashing Features! - SPEED DENSITY TUNING: Replaces OEM MAF based tuning logic with MAP based tuning logic, allowing for very big horsepower builds and removing the limitations of the stock MAF sensor. - MAP SLOT THROTTLE TABLES Each of the 9 map slots can now have unique throttle profiles, increasing the level of customization for each map slot. - BETA HP OFF-THE-SHELF MAPS: New Beta High Power Off-The-Shelf mapsbridge the gap between our standard Off-The-Shelf maps and a custom tune. More power at the push of a button. - ON THE FLY MAP SWITCHING: Instantly choose from up to 9 calibrations using the steering wheel cruise control switches or the AccessPORT, while driving! Video - FAST MAP FLASHING: Allows ECU map change flashing time to be reduced to 40 seconds or less! Video - KNOCK INDICATOR: View knock events, as they occur, on the factory in-dash display. Video NEW AccessPORT TCM Flashing Features! - ENHANCED LAUNCH CONTROL: Updates TCM to Nissan LC2 launch control logic with two user selectable launch control modes! Level 1 sets launch control revs to 3,300rpm (300 more than stock LC2) with more aggressive clutch engagement and throttle curve. Level 2 raises launch control revs to 3,700 rpm with the same clutch and throttle characteristics as Level 1. - CLUTCH GEAR LEARNING: Perform this factory recommended annual optimization without a trip to the dealership. Shift quality degrades as transmission components wear. Performing this optimization recalibrates the transmission, resulting in smoother shifts and improved driveability. - TOUCH POINT ADJUSTMENT: Use the AccessPORT to adjust the amount of clutch drag while stationary. Eliminate excessive creep or set clutch drag for the perfect launch responsiveness with +/- 7 levels of adjustment. - CLUTCH CAPACITY ADJUSTMENT: An essential adjustment for higher horsepower GT-Rs to eliminate clutch slip during full throttle upshifts. Increase or decrease clutch clamping force with +/- 7 levels of hydraulic pressure adjustment.
