Hi all -

I might just be whittling here after fixing all my various issues making my car run lean (mainly dead cat and, o2 sensors and maf) it now runs... rich on both banks at idle... not loads it reads around -8 to -10 on the ltft and between -2 and +2 stft both banks...

Any idea what to look for here ... should I be looking? Is this semi normal for this engine at 100k? Seems just to be at idle and no adverse issues yet no faults logged or anything. Current stable:
2006 BMW M6
2007 4.2 V8 S/C FF
Gone:
2002 4.4 V8 FF

Nothing to worry about.
Wait until it pops up a code I'd say.
But you do appear to be a serial tweaker so no doubt you'll have a go at adjusting the lpg map down a tad

It’s nothing to worry about in my view.
