is there anything special that needs to be done when converting to 2 bar os on a e38 truck? I know the ve is zeroed but when using a wideband in the factory o2 location (pre-cat)in OL I can't seem to get a workable table. the pcm is commanding around .80 during crank and it acts like its flooding(if I hold the pedal down it will turn over run then die). what if I enabled the maf and st o2s and let them populate the ve thru ltft. and then work off that table. idk I understand what I need to do but am having a hard time getting it done(first timer) where could the commanded rich be located I've put 1s in just about every place I know to
