off topic / traction control

[justin ivan]

I still feel that using brakes for traction control is less then ideal. 
While traction can be mantained utlizing this system, it can provide a ton 
of shock to the drivetrain. I feel that a spark/fuel cut is a more elegant 
solution, and one that should be attainable with the broad knowledge 
availble here and at other resources. Out of curiosity, what is you intended 
use for this application? To retrofit the family wagon that didn't have 
traction control as on option? I can't imagine it is for a race car 
considering that ABS is on board.
There is another programmable efi on the market from the UK that claims to 
do traction (they call it launch) control, the system is called DTA and the 
URL is http://www.badger5.co.uk/ look under engine management.
