Remap c30 from France

[Croissant]

Hello,
I'm writing from France.
I've just imported a volvo c30 from Netherlands.
It's a 1.8 liter petrol.
I want a remap for a conversion to ethanol e85 and a stage one.
The thing is that no one knows my engine or my ecu.
Can you help me to find a file and buy a file for my ecu 307889 61.
Or do you have any advices or contacts.
Thank you
Maxim Barsby
