DIY Traction Control

[Crescent Kao]

Hello,
  I've been following your TC/ABS discussion over the past week or so. I've
had this idea in my head for quite some time but never really got around to
trying to implement it - a traction control system that utilizes the stock
ABS sensors on the vehicle.
  There's currently a company that already produces a bolt in kit that does
the exact same thing, and will cut the fuel momentarily during excessive
wheel spin. Upgraded kits offer user specified wheel spin.

Here's the url:

Anyways, I have an Industrial Design and Computer Science background and
from what I can foresee, building and programming the software for such a
system should be that diffcult especially if it simply tapped into the
current on board ABS unit.

The only thing holding me back from pursuing this project is that fact of
reducing engine output during wheelspin via cutting fuel or retarding
timing. I'm clueless as to how to approach this from a programming and
hardware (laptop to ECM) interfacing standpoint.

My idea right now for a prototype is to simply tap into the ABS sensor wires
and feed the signal to the serial port on a laptop and write some code to
determine wheelspin. Further than that, I'm not sure how to continue. I
should mention that I'm also following the assumption that the current ABS
system uses/sends a digital signal from the ABS sensors (a data stream of
0's and 1's corrosponding to the rotation of each wheel).

Just throwing this idea out there. Anyone have any ideas?
