My car came with one, and tonight waiting at a bridge for 30mins i started to play and i got into different settings, i got into the speedo one cause my dash one is out but no speed came up, i dont have a manual but does anyone no where i can go read about it or how to make the speedo work?
thanks

May sound stupid but is the speed sensor for the turbo timer hooked up?
