Vtune3 is a program that uses the data collected with datamaster. HD04 and HD06 can collect data with datamaster. The flight recorder needs the HD06.
Flight recorder collects more than vtune data. It will collect any of the types of data that datamaster can collect. I see this being huge with spark data. Sometimes it can be tough to reproduce some of the spark events on a dyno. Plug the HD06 in the port and go ride. Normal day out with mama. It will automatically start and stop recording with rpm. So, you can go on a ride on Saturday, go for a ride on Sunday, and look at the data on a Monday. No buttons to push, no starting a recording, stopping a recording, all that mess. Just a normal ride and wife doesn't even have to know your messing with things. win, win
