A post from the newbie brigade - I'm getting closer (1 of many)

[KasaRyan at aol.com]

Ok it looks like all my complaining about how tough life is has turned a few 
sympathetic ears.  I must thank everyone on the list who has been helping me 
out, and I have noticed that they are mostly lurkers - just soaking in all 
that knowledge.

Here is where I am at :

1- I have read and digested Prog 101 - thanks Bruce.

2- I have a scan tool and know how to use it.

3 - A fellow read off my bin from the chip and mailed me another back - 
thanks - I'll get even with you.

4 - Another fellow modified my bin and showed me how to read it in a software 
package.

5 - I was muttering about eproms at work and the guy in the office next to 
mine asked if I could do anything with this. . . . He gave me an MCT-EPROM-4, 
 s/n 200682 four-socket eprom burner to play with for a while.   Said he 
couldn't find any software - can anyone help point me in a direction for this?

6 - What I have noticed is that this list has about 3 different Camps - those 
that deal in real hairy conversations with a high level of specialized 
information about platforms and ECM numbers and talk above some of our heads 
(for now),  Those (like myself) who are just starting to see the light of how 
all this stuff works and are now able to apply something, and everybody else 
- some who do this for fun/profit, or both.  Neato.

8.  As soon as I have to I will get myself a hex editor (at least once I 
understand things so I can personalize my prom ID)

7 - Questions - Instructions or an FAQ for WinBin or Tunercat would be nice. 
Because I would like to know what some of the controllable variables are and 
how they work. . .for example . . .Main Spark bias = 10.   Does this mean 
that the computer adds 10 degrees to everying in the tables or calculated?  
Or does it assume that you already have 10d static (I do!), or something even 
stranger?

8 - On transmission stuff - I have already fried one 4L60E and am determined 
not to repeat it again, and I see there are all kinds of things that can be 
modified.  Which ones should I mess with and how should they be adjusted.  
MAIN LINE PRESSURE tables - It looks like big numbers at large throttle 
openings and low speeds.  I guess more is better.  If I can stand the shifts, 
can I make these numbers bigger, is it percent, or an abitrary figure.  LINE 
PRESSURE MOD - some of these numbers are bigger and some are negative.  What 
does this do? does it change the PWM, and if so, does a larger or smaller 
number equal more line pressure?  same Q with DOWN SHIFT PRESSURE MOD.  I 
notice that some gears have mods and some do not - why?  NORMAL KICKDOWN 
SPEEDS and ENGINE SPEEDS.  does this mean if the either the WOT RPM or MPH 
are exceeded it will upshift?

9.  Looking at a factory bin and the one Howell burned for me, I can tell 
exactly why it ran poorly and where.  There are fuel discontinuities over 
4000 rpm, and the spark table is maxed out at 36 deg for just about every 
location below 2500.  

10. My next step - once I understand more about what I am doing, Is to simply 
take a factory bin and change the idle speed to 850, change the cylinder size 
to fit a 383, and change the IFR to 90lb/hr.  And drive it and see what 
happens.  I bet it will work pretty darn good.  Can I use the Injector Flow 
rate as sort of a gross fuel adjuster, or should that sort of thing be done 
in the table. (are fuel table values in percent of something or an arbitrary 
value?)

11.  Once I learn how - make one change at a time, document it, hot rod it, 
run the piss out of it and let the suggestions roll in.

12. Ok guys - your turn!
