I need to give the ECU a speed sensor in reading as it looks like I may have overlooked it according to the boys on the cliosport.:confused::scratch:

I'm a bit concerned about this myself, although my PH2 has an electric speedo - which hopefully will work with the Twingo dash, there is no input to the ECU, I can only assume that the ECU get's it's speed signal over CAN from the ABS computer (which I won't be running).
