That level of detail of the engine dynamics are covered by the models that Airbus sell as part of the simulation data package, and that make up a very large portion of the price of your level D sim.
They're also covered by some pretty strong non-disclosure agreements, and in the area of engine controllers, the information is export controlled. Indeed, the license agreements are so strict that only specified people who have signed the agreements are allowed to see the data and models. Breach of these licenses can lead to multi-million dollar fines for the company involved and criminal prosections for the companies and people who breach them. It would also make vising the Home of the Free and the Land of the Brave somewhat problematic, seriously upsetting plans to take the kids to Disneyworld, causing severe turbulence on the domestic front... anyway, I digress.
Hence you're probably going to find a great deal of dificulty getting public domain information.
Good luck though - I hope I haven't rained on your parade too heavily.
