Okay I never downloaded it but you have to download it to a laptop and plug the Diablo to it while your driving in order to save it??
The dataviewer software is on our website on the U7135 downloads page. You do not need the laptop in the car. You can log with just the Predator, and then upload that log to the dataviewer, then save and send that log anywhere you'd like. You also have the option of streaming data right to the laptop as well if you desire. This allows you to log unlimited amounts of data since there is no memory issue with the Predator holding the logs... Thanks Mike
