Have a chip burnt.
I've also heard that you can find the wire from the computer to the fuel relay (under the seat) and clip the wire. This way the signal from the computer to start dropping fuel never reaches the relay. I'm not sure which wire it is, but if you can get ahold of a wiring diagram for the computer, you should be able to determine the correct pin and wire color(s).
