For those that don't know, Cosworth makes the PDR system for GM and they also make multiple software packages for doing data analysis from the PDR files. While GM tends to promote the simplified "GM Toolbox", I've never liked the fact that it doesn't ever put the squiggly lines I want to see on the same chart and only shows you a subset of the data actually recorded in the files. Cosworth also makes a professional data analysis package called Pi Toolbox that works with the PDR. This is the same analysis package used by Indycar, Porsche Carrera Cup, and other professional teams.
The downside is that it's historically been pretty complicated to get going but I've done the hard work, so you don't have to. This video walks you through how to get the free Lite version of Pi Toolbox and get it all setup to use with PDR data in less than 10 minutes.
