VE Tables Fuel Tables Maps Igniton Spark

Well now that we're dun tuning we can all find a Mexican
restuarant and contribute to the methane problem, right.
Well ya if ya want, but there are just a few closing notes
I got..
  I have not read anything that says you can't run vaccum
referenced fuel pressure regulators with TBIs, the pressure
variance is usually too much, but if you run a second 
fuel pressure regulator, you can trim this variance.  This
is the only way out of not being tune the acclerator pump
features of TBI, since no commercial program I've heard of
allows ya to do this, however once you have things rather
close you can try other chips from other applications,
and put your tables on them.  If ya remember from the
good old days, a big block always took more acclerator
pump than a small block (hint). 
  The you can try adding timing to the spark table, and
remove a similiar amount from the WOT spark addition.
  The same with the fuel table, and WOT enrichment.
  When you start getting close, change only one thing
at a time, one thing only,  Move two and things might
seem fine but then 2 moves later everything takes a 
dodo.  
  One of the easiest errors is make is use too much
air filter, actually the problem is getting the air to
organize to flow thru the throttle body,  Having
several hundred square inches of filtering surface area
if fine,  but having a huge volume of air sitting on
top of the butterflies, can have it's down sides.  IE
when the throttles snap open, it takes/can take a
huge acclerator pump shoot to cover the delay in
this column of air to get moving.  If your using an
open element filter than I suggest doing this.
  Assemble the air cleaner housing, and element
as it would sit in the air horn.  Measure the distance
from the sealing ring portion to the lid,  any thing
more than an inch is too much in my book, and from
my testing, I have several cases to prove this.
Go to the hobby shop (say you had 3 1/4" dimension)
Lets also say the air filter sealing ring was 5" in diam.
You'll need enough thin brass to make two rings
Which 3" wide, and about 16" long.  To make a tube
5" in diam, and 2 1/2" tall.  The reason I say two is
you have to experiment, on the height, and that means
going too far, and that will ruin the first one.  I have't
found getting more than 1/4" close as necessary.
  HTH   Bruce    Anyone have any tuning questions
                          e-mail me, and I'll see if I got any notes
                          to write about.
                          DO NOT use staples for cone shaped

                          else with their hat
