I would keep RPM too. This would be my list of 5 OBD-II parameters, with Scangauge acronyms in parenthesis :

Code:
Digital MPH readout  (MPH)
RPM                  (RPM)
Throttle position    (TPS)
Ignition timing      (IGN)
Engine Load          (LOD)
But now I see the confusion with the original post :

Quote:
To that end there has been a discussion of which outputs we should be reading off the OBDII.

I a looking at Speeding, hard acceleration and hard breaking. The last two that have been suggested is fuel economy and time spent idiling.
In the above, there is the statement "reading off the OBDII". There is no direct parameter for "hard acceleration" or "hard breaking". You have to interpret the rate of change in MPH, possibly in conjunction with the TPS and/or LOD, for both of those. The same with fuel economy (complicated algorithm) and time spent idling (RPM at 0 MPH and 0 TPS).
