its jsut it has to drain the power out of the ecu so it is blank. then when you start it again, it will run funny for 2secconds rev low then rev high. you never know, you might get more power out of your car. i certinally did.

the easiest way to reset it, is to.
undo the battery terminals.
put you foot on the brake pedal for a good 3min's and leave your headlights on.
