I'm in the process of building a data logger for my car to capture items that I cant get through the gps.  I'm using an Adafruit Arduino with an M0 microcontroller.  I have chips to support logging other variables.  10 Hz gps logging for line selection.  Accelerometer and gyro for G information and yaw pitch and roll.  A radio chip to capture our local start and finish line.  I also have a individually addressable led strip for a linear tach.

Id like to connect it to something that accepts elm327 commands (i have a bluetooth reader I can tear apart).  Is there a place to find the source code for me7 logger so I can program my logger to grab parameters deeper than just the PIDs?

Thank you very much
