Yes it is possible to log data. Have a look at Fastchip | Megane Sport Forum and RSTuner (fastchip.nl)
The standard RS Tuner software can be downloaded from the Fastchip website. The unit doesn't have any additional modules installed on it.
A Windows laptop is needed. You also have to make sure that the RS Tuner module is not locked to any car, otherwise you can't do any module programming with it, only data logging is possible. To get it unlocked the RS Tuner reprogramming license costs 69 euros.
