Accessport V3 Hightlights
Larger, full color, higher resolution screen
We super sized the screen for ease of use and better monitoring. Full text help menus, multi-gauge layouts, full map descriptions and more. This screen has room to spare – so no need to run back to your laptop.
Customizable multi-gauge display
Want gauges? No problem. The V3 now supports up to 6 fully customizable gauges with 1/1000 resolution. Monitor all the parameters you want to see and customize each layout for street, strip or track.
In vehicle mount, with on/off switch
There is nothing we like more to see than an AP peeking over the dash. With the on/off button and using the included universal mount or vehicle specific options, there is no reason not to run your AP in-vehicle.
Faster and easier to use with a familiar face
We listened to what you wanted. Use your same maps, monitor your same parameters, and troubleshoot your same codes, but now with more. More speed, more memory, more map storage, more live gauges, and more troubleshooting help.
Is it your Accessport or our Accessport? It’s yours. Customize it as you see fit. The new V3 comes with 2 interchangeable bezels, blue and grey, or put your own touches on one. Our favorite is the chrome one installed in our GT-R.
