Some commands are still missing from the list. And there is more undefined too.
Interesting to look as the similarities and differences between your command collection and what I find for '97...

In the '97 code mode $ae submode $40 has no other parameters and I believe is used to clear out the short term fuel trim table (both left and right).
code is
