Mods to '85 GM TPI ECM

["Jim and Sharon Brady" <bradyiii@shore.intercom.net>]

Hi, my name is Jim Brady and I just joined the list a few moments ago.  My
current project is my '87 Monte SS.  My Monte is equipped with the GM
TPI(Tuned Port Injection) system consists of an '85 computer(I assume I have
an '85 computer because it had a Bosch MAF burn-off box attached to it) with
'87 hardware.  My original motor was a 305 and the system worked perfect.
My new setup is a 383(stroked 350) with a T56 manual trans.  The only
changes I have made to the system since I upgraded from the 305 to the 383
is 24lb/hr injectors and a fuel pressure regulator.  Everything works great
except full throttle.  I understand full throttle switches the ECM to open
loop mode leaving the EPROM to feed the system pre-determined values.  Aside
from improving my full throttle condition I would like to monitor the
parameters of the running motor.  What do I need to approach this project?
I assume an EPROM burner, cable for the aldl connector and software.  What
can I manipulate with the software?  How about the EPROM.  I am new to this
and would appreciate any help you can give on this matter.  Thanks.
