70-80% load puts you in the heart of peak efficiency. This does not mean 70-80% throttle. To get this load requires low throttle openings at low RPM and highter throttle opening at higher RPM. This is where a SG is useful, where you can monitor engine load. What I have found on my wife's Matrix is that the auto transmission kicks down to a lower gear at 80% load, regardless of RPM. So if you can learn how far you can push the throttle down to a point just before it kicks down in every RPM situation, chances are you are accelerating in the 70-80% load range.
