A330 FLX Temp vs EPR/N1


I'm toying with some figures on the A330-200 (RR), and wondering if there is a way of deducing the Flexible EPR setting for the Temp inserted.

I realise the Flex EPR will be dependant on the OAT, and the Pressure altitude as well as the FLX TEMP entered, but is there a graph anywhere or a formula or some such? I have access to some performance tools which give the FLX TEMP and the V speeds for a given field, but in the output it doesn't give the EPR or Rated N1.

The closest I've found is a graph, but that's for the GE CF6 engines. Does anyone have a graph for the Trent 700 perhaps?
