I have been looking at the logger operating manual. And the data files are saved in DIF (Data Interchange Format). It should be fine to import into most graphing packages.

Of electrical interest -

The Throttle Position Sensor (TPS), on the R motor, has two outputs. One of the outputs is a 0-5V range, covering 0 to 23 or so. And the other is from roughly 20 to 90. This will affect the way you interpret your data.

It is useful to see Throttle Position as a 0-100% (idle to full throttle) value. The TPS on our motors will not allow a direct interpretation of a single 0-100% scale. But the software 'data viewer' supplied with the logger should allow the viewing of two scales. One labeled 0-20%, and the other labeled 20-100%. This will require voltage measurement and software configuration by the user.

You will be able to configure two of the logger's analog inputs for the TPS to do this. But data shared from other's bikes, and read on your software MAY require some adjustment.

Sharing data MAY require the sender to provide their software 'scale calibration' values, so that when you share data, it will be consistent. The software's native file format may save these 'scale calibration' values so it will all be taken care of.
