? about ecu for sentra se-r

[Ronald S. Chong]

hi:

anybody know where i learn about the innard of the ecu for the Nissan
Sentra SE-R?  in particular, how the data in the eprom/rom/prom/eeprom
is organized?  from my limited understanding, the chip basically holds
a table to correlate air and fuel, among other things.  any clues as
to where i can discover this stuff?  the dealer?  (joke) is that
propriety information (and therefore "top secret")?  also, is the ecu
based on a motorola controller or some other cpu?  i like to learn how
to to modify the table in the ecu.  doing that is a long ways away,
but i gotta start somewhere.

thanks.
