BLM quesitons

[JN]

Questions on MAF equipped 89 Vette.  Using Diacom for some time now and have
some questions about the different cell numbers used for fuel trims.  What
tables dictate the amount of fuel used in open loop mode?  I understand that
in closed loop the MAF, O2, etc. determine the proper amount of fuel to
deliver and adjust the short and long term fuel trims.  What is modified to
control the fuel delivered in open loop and PE?  I assume its the MAF tables
but I need educated on what the values represent.

I don't want to ask questions that don't belong on the list (too basic).  If
I am please let me know.
