I believe that Scangauge will report exactly the same data, as it is all my ECU sends out. But perhaps some more fortunate user will confirm this (I believe Piwoslaw has both??)

Nope, I only have the SGII (but 2 of them, so you were close!). I'm not counting the on-board computer, as it is a dirty liar and cannot be corrected, ahem, recalibrated. Mine does not report fuel pressure nor oil temp (though I doubt my Pug has a sensor for the latter?). My suspicion is that load is calculated from other parameters (RPM, intake manifold pressure, injector timing, etc.), but I cannot confirm whether it is calculated by the SGII directly, or by the ECU and then sent to SGII. The latter case would be cool if I ever make an OBDuino-based load-dependent throttle, but I'm sailing Off Topic...
