I'm trying to control my two DC motors through the sabertooth 2X25 and a joystick, but my joystick values are from -1000 to 1000 and i want it to be from 0 to 255 any ideas

This is a common issue. Use one of the scripting modules to scale that value down. Have a look at the Joystick robofile at the bottom of

which has that same/similar issue.

which also use the joystick module and have to scale that value.

It is better to use Packetized commands vice trying to parse the direction and speed components. Just remember to send the "AA" byte to wake the controller. I've had very good sucess with this.
