The Starlane Corsaro K is another kart dash module. This one has some extremely cool features. The dash and the connectors to the sensors are housed in two separate physical units that communicate via Bluetooth. The dash will also communicate to your computer via Bluetooth to upload data. The remote even has a mini solar panel on it so you don't have to charge the battery. The main control of the dash is via its touch screen.
The next innovative feature is the ability to take your track routes and overlay them on to satellite maps. Why is this cool? Because by combining them you can see which paths through the section of the tracks are faster. What? That is so cool, but they didn't stop there. You can upload your lap, and compare it with other people's laps. So you buddy could post his hot lap to teach you how to improve. You can also take video of your ride, and then overlay captured data into the video.
And yeah there's all the other bits you'd like to have in such a system like EGT, and CHT sort of stuff. Plus GPS, RPM, oh and least I forget--it will infer your transmission gear based on speed and RPM. Yeah this is one cool box that is setting a pretty high water mark for its competitors.
Near as I can tell the software only runs on MSW, which is sad, but you can probably run it in a virtualizer if you don't have a crapy OS machine.

Why the K? The K is for the kart version, which has two temp sensors, and RPM. The other ones have more features, but the price goes up. You can expect to pay just under $500 for this dash setup. From what I've read that would include one sensor. But you can get a K type sensor from lots of places.
Here's a video in German explaining, well something.
Here it is installed on a bike to give you some idea of scale.
Here's an overlay video.

There are some different screen layouts, and even a fancy color screen version in the Pro model.
