The most complete GT-R tuning solution on the planet
The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your GT-R. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our 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.
COBB Tuning provides Off-The-Shelf map calibrations for common modifications for a given vehicle. Our Off-The-Shelf maps are extensively tested on a wide sampling of beta test vehicles across a wide geographic area prior to being released. This testing ensures that the Off-The-Shelf maps work properly across all atmospheric conditions and can safely accomodate fuel grade variances across the country.
The AccessPORT comes pre-loaded with maps to get you on your way, right away. Once the AccessPORT is installed on your car, you will have the following Off-The-Shelf maps to choose from:
Stock Mode: The stock mode map uses the same calibrations that came from the factory. The stock mode map is a great way to re-establish a baseline when comparing tunes as it lets the engine behave the same way it did before installing the AccessPORT.
Stage1 Maps: These maps are performance maps that are designed for vehicles with no engine modifications or mild modifications such as a cat-back exhaust.
Stage1+ Maps: These are performance maps for vehicles with an upgraded intake system. Aftermarket intakes can dramatically change the airflow pattern across the MAF sensor which can generate incorrect readings and makes the engine run lean or rich. A Stage1+ map recalibrates the MAF sensor for the specific aftermarket intake system you are using.*
Stage2 Maps: These maps are geared towards performance upgrades that reduce restrictions in the exhaust system. If you have replaced the factory downpipe from the turbo or replaced the factory catalytic converter with a high flow cat, a Stage2 map is what you are looking for.*
Stage2+ Maps: These maps address both upgraded intake modifications and the high flow exhaust enhancements of Stage2.*
For even more map selection, be sure to visit our Online AccessPORT Map Database. Click on the Maps and Map Notes button that corresponds to the manufacturer of your vehicle. Here you will find a wider selction of maps that are designed for additional aftermarket parts manufacturers, race fuels, turbo upgrades, ethanol and more!
