EFI Questions

Tried the plug cuts.  Looks nice and clean (no detonation) but I already
know that its OK on avgas.  Plugs are a medium grey, with probably a slight
browning of the ceramic tip (NGK BP6S plugs).  And yet the car is still
running very rich (I think around 0.8-0.9V is rich).  So how does a plug
look like its OK and yet all other indications are that its rich (got me
puzzled) ?

When in doubt read the spark plugs.  AV can look lean, but the signs of
detonation are always present, from what I've seen.  Now, I'll fully admit,
it's been years since doing much AV gas reading.  Try a load of good
racing gas if you have trouble reading the AV stuff.  And I've got zero
time reading australian AV Gas.
  Pipe coloring is dead in my book.
