Just had a reply from Aim UK, and they said that the speed should come from the ecu along with the rpm, gear and the rest of the sensors. As far as I know there is no speed sensor as standard in the cossie, and I haven't had one fitted. I know I can fit a sensor and connect it up to the Aim dash seperately, can anyone confirm that a cossie doesn't have a speed sensor, even with a T6 or am I wrong?

They also want £745 for one, any recommendations on cheaper suppliers, otherwise I'll search the net and ebay as usual )
