 It's crazy to think that the version 3 access port has been around for nearly half a decade already, but still holds up as the best plug-and-play engine management device in the market. The jump from the version 1 to the version 2 in terms of feature support and functionality was massive, so it was a big challenge for the engineers to come up with a way to match that level of improvement on the third generation access port while maintaining the familiar experience that thousands of customers had grown to love. At the end of the day, the best solution was to take everything the V2 did well and simply do it better. Do you like monitoring live data? How about six gauges at once? Data logs are nice, right? Now they record at a higher rate for longer time. Waiting for a map to flash can suck. Now it happens way faster. Do you like custom features that you can adjust on the fly? Here's a bucket load of them. It will just keep adding in with free updates over time. Do you hate trying to troubleshoot weird behavior? No worries. Screenshot your check engine lights and custom error messages and send the images to Cobb support for friendly help. You don't have a silver car, you say, but you want your access port to match your paint job? Bam! Custom swappable face plates? I could keep going, but long story short, the V3 at face value kind of seems like a V2 with a nicer screen, but when you actually use it, it is leaps and bounds better in every way and nothing makes us happier than seeing how it transforms a car.
