Check the Techniques page in this month's Miscellany - I think I saw it there.
Yep - back page:
"With the factory diagnostic equipment we are able to offer the latest ECU flash for the +4GDI. This removes the high revs on first start, gives an improvement on MPG and can be carried out when you have your car serviced.
We are also able to carry out an ECU emissions reflash for the +4 SuperSports".
