What do you know about data logging?

[dontlifttoshift]

I have been researching data loggers lately. I would like to accelerate the learning curve as a driver and setup guy and I think the information would be valuable, to say the least. Mostly autocross with track days and PT events mixed in.

I have no interest in an app based setup, would really like a dedicated device. If I could take it to different cars that would be a huge plus.

From what I see the DL1 is the standard in the industry but I have been looking at this http://www.race-technology.com/ax22_8_938.html Easy in and out, obdII compatible, GPS, and digital accelerometers.....from what I can tell it uses the same software as the DL1. I also think you can pair that up with their video4 and overlay information on the video with up to 3 camera inputs.

Anyone with direct or general experience regarding product from race technology or data logging in general?
