Introduction to datalogging

KManager can datalog from the ECU to a laptop when connected to the ECU and the vehicle ignition is switched on.  Later KPros have an on-board datalogging capability. Note that some sensors are not datalogged if the engine is not running.

KManager uses frames to datalog. A frame is like a snapshot of all sensor values taken at one point in time. The number of datalog frames and datalog length is shown below the menu bar in the main window.

Datalog files have the extension .kdl, and normally are associated with KManager so that double-clicking on a datalog file will open the recording in KManager.  If the file extension association does not work then open the Settings dialog and check 'Associate calibration and datalog files with KManager'.
