Thanks again man

FYI, a ScanGauge -- or any OBDII based MPG meter -- won't work reliably on a lean burn system (because it extrapolates fuel consumption from air consumption at stoich, plus additional allowances for open loop).

You will need to use an MPGuino or equivalent if you want to know fuel consumption while fiddling with A/F ratios.
