AccessTUNER Custom Tuning Software for Nissan & Infinti


AccessTUNER allows custom tuning of Nissan and Infiniti ECUs to extract maximum power for virtually any performance modification, including forced induction. Engine tuners can create custom calibrations for vehicles equipped with aftermarket intakes, exhausts, cams, turbos, superchargers or any combination of performance modifications. The results are impressive gains in power and torque with all of the drive-ability and sophistication inherent in the OEM ECU.

AccessTUNER puts control of vital engine parameters into the hands of the tuner, such as intake cam advance, exhaust cam advance, fuel, ignition, knock, engine rev limiter, speed limiter and many more. Customizable data monitors let the tuner choose which channels are monitored to see how changes impact the behavior of the engine. The built-in data logging capability captures data from multiple channels across the entire rev-range, allowing detailed data analysis after a dynamometer test. 3-D graphical mapping gives the tuner a comprehensive view of engine behavior across three axis to evaluate where performance can be maximized. An integral dashboard shows the tuner-chosen gauges to be displayed during the tuning process.

AccessTUNER Pro is tuning software for professional tuning facilities. AccessTUNER Pro allows for unlimited tuning of any AccessPORT-equipped Nissan 370Z, Nissan 350Z, Infiniti G37 and Infiniti G35. The professional tuner can choose to lock the map in order to prevent unauthorized reproduction of the map or inappropriate use on other vehicles.

For the Month of July, AccessTUNER Pro will be discounted 40% for all new ProTuner Licenses. Additional discounting is available to current ProTuners. Please contact Sales at 801-713-0443 or for additional details. AccessTUNER Race Beta is self-tuning software for the end user. AccessTUNER Race has all of the tuning power of AccessTUNER Pro, but is married to a single AccessPORT. AccessTUNER Race Beta maps can be shared with other AccessTUNER Race Beta users. COBB Tuning Nissan-Infiniti Tuning Guides are designed to walk the user through the steps necessary to properly tune the ECU in a safe and straightforward manner. AccessTUNER Race Beta is free of charge to AccessPORT customers and can be downloaded by filling out the AccessTUNER Race Beta registration page.

COBB Tuning is dedicated to improving the AccessPORT line of products for Nissan and Infiniti enthusiasts. The release of AccessTUNER software is the first step in an intense program to bring COBB Tuning products to the forefront of the Nissan and Infiniti performance markets. Stay tuned for more exciting news in the near future.

anything for 97 q45 would love to release more power if not anyway

Travis on August 6, 2009 says:

At this time we have no plans to release an AccessPORT for the older Infinity platforms. The AccessPORT is only compatible with G35 and 350Z models back to 2003. We will be concentrating on new Nissan and Infinity models as they become available. Thank you for your interest in COBB Tuning products.

Is the accessport for 350z also work on the g35 , same year and both 6speed

Gary on January 4, 2010 says:

Nhan ha,

No, the 350Z and G35 are different part numbers and are not interchangeable.

Z on May 30, 2011 says:

Do you support JDM V35 Skyline 350GT? Same as G35. :)

    Travis on June 8, 2011 says:

    Sadly we do not. At this time we only support the R35 GT-R.

Rick on April 21, 2012 says:

Sad to hear Cobb is not selling parts for Infiniti anymore. Is there any way to still get an AccesTuner for a 2009 G37?

    Ian on August 10, 2012 says:

    Unless you are able to find a used one. Sorry for the bad news!


Andy Lam on October 14, 2017 says:

    Marshall on October 17, 2017 says:

    Hey Andy, we do not have plans to add Accessport support for additional Nissan vehicles at this time. Sorry for the bad news!
