My understanding is that the SG does
not have access to injector pulse width/frequency, and that it's extrapolating fuel use assuming stoichiometric ratios, based on displacement, RPM, speed, etc. So it can't actually "see" lean burn mode.

Two Caveats For Hybrid Car Owners. First, I found the ScanGauge mpg calculations cannot accommodate the lean burn engine found in specific hybrid cars, such as the 5-speed Honda Insight. - Source

Maybe this has been addressed since I first heard about it. But I would certainly check into it before ordering a SG.
