I have a device that attaches to the OBD II port as does this "Progressive" gizmo.My thing can be set to record up to five different parameters at one second intervals.I have mine set to record speed,engine RPM,manifold intake temp,battery charge and another thing I can't recall.Mine must be removed periodically and be connected to a PC to view the data...it doesn't transmit any info.My hunch is that the "Progressive" gizmo records the same kind of data and that it,too,must be removed and hooked up to a computer.
