Quick Overview

This Product has been discontinued. Please see our updated listing for the newest version.

Sku # : Cobb-AccessPORT-Nissan-GTR-MW2

Unleash hidden performance from inside of your Nissan GTR's engine with the Cobb AccessPORT ECU Flash Tuner. The Cobb AccessPORT ECU Flash replaces factory settings such as boost pressure and engine timing with more aggressive calibrations that result in hefty gains in horsepower and torque.

The Nissan GTR Cobb AccessPORT allows you to chose what type of map you want to run on your car on the fly, whether it be performance or fuel economy based. For those looking to extract maximum performance from their GTR the Cobb also includes maps that can take other modifications into account such as downpipes, intakes, and exhaust. Most importantly the AccessPORT can be installed by ANYONE and all that is required is plugging into the vehicle's OBDII port.

Just ordered my Cobb AccessPORT! Alan was very patient as I had many questions about the technology compared to everything else out there. He was objective in his explanation, and answered any questions I had. Great price on a great product I'm sure. I just can't wait to get in and put it to work! Will definitely do business with them again.
