type the codes in where you would normally type your name. They must be
all in capital letters and be preceeded by EAC.
for ex. to get the 800 h.p. car type EAC POWR instead of your name. I'm
not sure if this works on the demo but it works great on the real game.
The other interesting code is EAC RALY. Use this code on Rusty Springs.
