Start by reading Programming 101, the the archives here and at =
DIY_EFI. Visit http://www.tunercat.com , then syty@syty.org, then the =
GN list. All have various amounts of ecm info.. There is even a =

Once you have a good grasp on those materials, it will be much =

Subject: Question from newbie
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!!
