How can i get the telemetry data from Dirt3?

[flyhe 0]

The codemaster says the data format is the same as LFS in Dirt3,  but nothing happened after i edited the setup file in ../Documents/my games/ directory . So i edited the setup file in the game directory both , but nothing happened again.

i edited hardware config xml file  <motion enabled="true" ip="127.0.0.1" port="20777" delay="1" extradata="0" / "1" / "2" / "3" >.

The point is I've got the telemetry data from LFS, and my 4dof motion plat runs well.

Could Someone tell me why? And sorry for my terrible English.
