'94 & '95 LT1 Ecms

[ChadBeebe at eaton.com]

I just found the GM ECM web site and have read through alot of
the archived messages and would like some clarification of
what I have read specifically on the LT1 ecms.  

What I have understood is that these ecms are a flash style,
meaning I have to erase the program and then dump a new
program in.  I am also interested in the memory address for
the fuel and spark tables.  The main question I have is, is 
there enough free space in memory to have multiple tables
that get used say if a certain switch is set?  I was thinking 
this might be a way to have a fuel/spark table for economy
and another one for performance.

Also where can I find the software to write to these chips,
and does it work through the ALDL connector.
