I hit the 3 cells with "5" and the 4th cell with a "12". Blended the cells together. IIRC I also did add some advance to the 800 rpm column. That way if the idle drops, the ecm adds timing to help recover. Easier then it having to add fuel then take away fuel as rpms bounce.Not sure I should mention this, but for those that want to research a bit, on the "ecm config" screen,  you can change the volts, the o2 sensor references as the midpoint. It will skew the O2 sensor which ever way you bias it. If you make the midpoint, say, .5V the entire map will be richened up, as the 'new midpoint is now .5V</blockquote>
