Ok guys,=20

    I have been floating around here for about a week now.  I joined =
this list to learn how my ECM in my 89 (MAF) Corvette works.  I have an =
understanding on all the sensors and their functions and how the ECM =
uses this data.  What I don't understand is how to change spark maps and =
fuel maps to fine tune my modified motor.  I plan to build a 383 soon =
with larger injectors and there is not tuner around the Pittsburgh area. =
=20

Questions are:

1.  Where can I learn how to change the program in my prom? =20

2.  I want to know how to lean the injectors at idle when in open loop.  =
(idles rich now)

4.  I want to learn to optimize WOT AFR.  =20

5.  I want to learn to increase idle speed due to a larger cam. =20

What I don't have is an understanding if hex values, prom address and =
what they mean.  Is there a book I can buy that explains all of this?  =
Is there such a thing that I can buy that will let me change my prom =
program via a laptop and my ALDL connector? =20

Finally, if I don't have a good understanding of how all of this works, =
I don't want to be a burden to the list so maybe I should quit the list. =
 I can ask alot of questions!!
