here i have a hondata s200 w/boost option for sale. it includes:

interface box
hondata software cd
interface cable
datalog cable
push button
usdm obd1 p28 ecu (chipped)
boost option (installed)

im asking $575. all you have to do is plug it up to the ecu harness and get it tuned. i bought it two months ago, i really dont have the time to get it tuned, so my loss your gain.
