Nissan R35 GT-R Cobb AccessPORT Tuning Package

Please note that the Cobb tuning software no longer supports Speed Density style tuning or race pipes

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.

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 40-60+hp with the Remote Tuning Session option.

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 base performance maps for your GT-R.

How Remote Tuning Works:  AAM Competition Cobb AccessPORT GT-R Pro Tuning is a straight forward process.  A laptop or desktop computer is required to complete the tuning.  Email your vehicle's model year along with a full list of your vehicles upgrades (please feel free to submit your model year and list of upgrades using the form below).  Once received, we will send (typically within one day- but it can take as long as 3 or 4 days) you a file that is your vehicles new Pro Tuning File.  You copy this file from your email to your laptop or desktop computer.  An easy download of the Cobb AccessPORT Manager software (free download) to your computer is the next step.  Then, connect your Cobb AccessPORT to your computer with the supplied USB cable.  The Cobb AccessPORT Manager software will prompt you to check for firmware updates, and automatically update the Cobb AccessPORT if needed.  Next, using the Cobb AccessPORT Manager load your Pro Tuning File we email to you onto the Cobb AccessPORT.  Then, go to your vehicle and using the supplied cable connect one end of the cable to your vehicle and the other side of the cable to your Cobb AccessPORT.  The vehicle connector is very easy to get to, it is located right underneath the steering wheel.  Once connected the entire process of flashing (programming) your Pro Tuning File to your vehicle takes less than 2 minutes!  In 99% of the cases (simple bolt ons) this tune will be 100% perfect and this is the final step.  Those who have more upgrades done to their vehicle outside of simple/popular bolt ons we offer (at no additional charge to the remote tuning option selected above with this purchase) up to 6 revisions to your Pro Tuning rom file during this purchases remote tuning session.  These revisions are achieved through datalogs.  We will send you a list of parameters to datalog and then you email the datalog back to us, so that we can analyze your vehicles performance, and make adjustments (remotely tune your vehicle).  In the rare case more than 6 revisions are needed, we can offer additional revisions and support for $50/revision.
