GM computers

[Ryan A Erickson]

	Does anyone know of some sources or have some info on GM computers.
My intentions are to change the intake manifold and cam on a GM 3.1 L V6, 
turbocharge it and throw it in the back of a cheap '84 Fiero.  I would 
also like to be able to adjust as much as possible from the cabin of the 
car (A/F, spark timing, boost, etc?)  Now if one had a lot of money you 
could buy stuff that would do this, but that takes all the fun out of a 
do-it-yourself project.  What I'd like to know is about the different GM 
ECM's, their inputs, their EPROM's, the location of the tables on those 
EPROM's;basically, I'd like to know everything there is to know about GM 
ECM's.  
					Thank you,
