Purchase Disclaimer: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b).

The Accessport V3 is the world's best selling, most flexible ECU upgrade solution for your GT-R. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications or use custom mapping for any modification level. It's the last engine management solution you'll ever need

The new in-cabin mountable Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations. 


Simple Installation / Uninstall:  Everything is included for the simple installation!  Intuitive on-screen instructions identify your exact vehicle and available maps. Revert your ECU to exactly as it was before with the easy to use Uninstall option from the main menu.

Trouble Codes:  Read engine trouble codes to diagnose issues. Clear them when resolved.  Prevent expensive trips to the dealership.

Gauges: Use your Accessport as a gauge to monitor boost or any other live information, directly from the ECU.
