101 clarification

Updating the programming 101 summary, I got some questions:

Spark table, 0035 to 0106 (14x15) is referred to in this email:

http://efi332.eng.ohio-state.edu/diy_efi/archive/archive_num_97;lines=88187-88222

Only the size is mentioned, not the location or description.  I found
the location in another email I had.  It looks to me like it's laid out
in memory as a 15x14 table, by rows.  Can someone explain to me what the
two axis of the table are, and what units the table value is in?
-----------------------------------------------------

Similarly, in a non-list email I see that the fuel table is located at
037f-03c6 (or 03d7), and is 9x8.  From looking at a bin, it looks like
it's 8x9, laid out by rows.  Again, what are the units for the axis and
table values?

Bruce posted a correction saying that this table actually extended to
03d7 for high RPM, instead of stopping at 03c6.  That conflicts with
another email that said there is a WOT fuel adder table from 3c7 to 3d7.

Can someone clarify what size the fuel table is, where the WOT fuel
adder is, and the units on both, please?

-----------------------------------------------------

On the subject of TPS enrichment, Bruce mentioned three tables that
approximate an accelerator pump.  MAP delta, TPS delta, and "quantity". 
Here's the email that discussed it:

http://efi332.eng.ohio-state.edu/diy_efi/archive/archive_current;lines=14793-14857

delta TPS and MAP I understand, but what is the "quantity" table?

Note that this installment has the subject "porgramming 101", so if you
do a subject search for programming 101 you won't find it...  Bruce, at
least spell check the subjects!  :-)

-------------------------------------------------------


Thanks in advance for the help, I hope these aren't too basic, but I'm
in learning mode here...


Oh yeah.  Looking at the summary of tables posted so far, there is a lot
of address space that hasn't been determined yet.  Is this code?  Or are
there lots of tables yet to be discovered?  If someone knows the
location of code in the PROM, please post it and I'll add that to the
summary also.  Keep up the good work Dr. Pelican et. al.
