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.
