It appears to be a single transistor serial cable. Should be sufficient. Winaldl will probably work just fine and be simpler to get started with. Tuner pro is a tuning program, so it has three different smaller "apps" that you have to load in it to see, read, and change data.
If your wanting to take up tuning, stick with Tuner pro. , if you only want to read your car, use winaldl.
Which car are you wanting to gather data from? Year and engine?
