DFI controler desription

[David Doddek]

Thank you all for the interest.  I have responded to the list to keep from
sending out the same message over and over.

The system I developed is made for the beginner.  It is not intended to be a
super featured unit.  At least at this time.  One uniqie feature is the
ability to tune the basic fuel parameters using a screwdriver just like a
carb.  A bit more precise than a carb though.  It also can be further fine
tuned using an IBM pc.  It is however fully possible to run a car without
ever attatching the pc, especially on stock cammed engines.  It is currently
batch fired and can run either throttle body or port with high or low
inpedance injectors.  A future version will be atempted to be sequential
with no engine mods.  Going to use a pickup off of the distributor.
Currently it has no ignition control, but the next version will, I hope.
The next version will also have closed loop ability.  It currently runs
speed density and has inputs for engine temp, throttle position and MAP.  It
will trigger directly off of a coil.  It will work on one to 8 cylinders.
The screwdriver adjustments are for Idle, Power point, Wide open throttle,
Accel, Choke.  It connects easily with just a terminal strip.  I have used
it on motorcycles and cars.  Even have one running with only a Map sensor.
It even starts ok as long as it is not too cold out.  By switching out a
stock control on a 280z for my control, the car pickuped a full second in
the quarter. I am currently adding new features and changing the startup
portion of my code.  I found some things that I did not like.  After all I
use one on my personal daily driver.  The Pc software will allow on line
changing of parameters an monitoring with bargraphs.

I would like to know if there are any features that people would like.  Some
of the things that I am thinking about are:
  Fan control
  NOS control
  Controlling Ford and GM factory direct ignitions with stock crank sensors.
Would makd for easy retro of new engines like the Ford 4.6

What other features would people like to have?  Let me know and I will work
on them.  

I am expecting to have a new control out by summer and will have a more
complete description and solicit interest then.

Some people expressed interest in schematics and info.  While trying to sell
a product, I can not give out this info, I would be willing to answer
questions to aid some one in making a school project work.
