It's called andromeda. It was a mod you had to get installed my a guy named Juan. As far as I know it would bypass any of the compression and output raw sensor data straight from the sensor via USB. There are still a bunch of them kicking around and go up for sale on here from time to time. If you do a search on here you will find a whole bunch of threads on the subject. I would post some links but im much to lazy.
