I'll start. I am using Cosworth
Pi Toolbox Lite which is the native software for the Chevy Performance Data Recorder (PDR) hardware found in Corvettes, Camaros, and Cadillac V-series cars. The capabilities are very similar to AIM Race Studio. This is the free version but there is a paid upgrade that allows for more worksheets, video comparison, etc.
GM/Cosworth actually do not broadly advertise that the PDR files will work in here, and instead direct you to a dumbed-down version of it known as
Cosworth Toolbox for (brand). I still find this useful since it allows me to have the video overlay, something that costs about a grand in Pi Toolbox as part of the upgrade.
Attached is a screenshot of one of my primary worksheet/dashboard with two laps worth of data, zoomed all the way out to show the entire lap at once. I had to downsize it a bit due to forum limitations.
