GM just doesn't have that much RAM in the C3 or P4 series of ECMs to use
a 9x11 table.  Probably some VE tables aren't even that big!

I added 2k of non-vol static RAM to my ECM, and put the VE table in it.  
I do alter the VE tables, instead of using a BLM, in an attempt to get a 
real good VE table.  Lot's of little things are making it fun.  Wonder
if I will ever get done.  ;-)

As an answer to your question, I have seen as little as two cells, (idle
and off-idle) and as many as 16, with values in-between.  See another
post for an example.
