A couple comments. This is connected via the OBD-II port on your car. So yes it can technically measure any metric that the OBD-II reads. If you are in need of serious datalogging, this is not the way to go...here's why. The OBD-II port has serious issues with sampling multiple metrics at the same time on a high frequency rate (i.e. 1 sample/sec for multiple metrics). This will create a lag and make it difficult to properly datalog. Yes you could probably do one item at a time and measure that, but then if you do multiple runs with multiple metrics being record the environment and engine parameters will not be identical so they can not be compared against each other.
