i saw the correction factor at 50%, and i then saw the rpm at 388 RPM (according to his meter) and yet his tach showed about double that. so let's see, 780RPM Idle reduced by 50% (hence the "") and you get 390 RPM. seems to me like he did the equivilant of calibrating his SGII to read that he was hardly using any fuel when he was using the normal amount.
