You need a windows laptop with ProTune II and a lead to plug it into the mobile phone type socket under the cover on the ECU.

Thanks Ian - much appreciated- I was told there's a requirement to fit a 16 pin connector point under the dashboard - Mmmm
The 16 pin connectors are used on car OBD-II systems, its a mini USB on the S & S, M3W as shown below once cover removed.
