/********************************************************************
This example is built upon the CANAcquisition class and the OBDParmameter class using extended OBD2 ID's
This example shows how to set up periodic data acquisition of OBD2 paramters based upon
standard PID's. If you'd like to add another paramter,simply copy one of the definitions and modify it accordingly. 
You may also need to add a new PID to the "OBD_PID" enum in the header file.
