JEDD,

What are your primary goals for a data system. Are you after great videos, driver development, chassis development or just monitoring your car vitals. How much $$$ are you willing to lay out.

AIM is popular because it offers many of the features of Pro systems (Motec, Pi/Cosworth, Bosch, etc.) at significantly lower cost. The VBOX systems have significantly better video capture and functionality than AIM.

There are pro's and con's to them all.

The K-line output from the Boxster ECU is far too slow to really capture meaningful data. It has many of the right channels. TPS for instance would not even remotely show you accurately where you were full throttle on corner exit. That why additional sensors are the way to go, or taping the signal from the TPS in this case.
