e38 2 bar

[geneass]

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

If you do not post the tune/log and complete build information there is no way to help.

So until you figure why one bank is lean and the other rich this will never run. Ground? Might want to disable STFT to see if it is an O2 sensor.
