The eBay link I posted was for an 848 streetfighter ecu. Not sure if they are the same as the 848 evo, but if you search ebay for "ducati 848 evo ecu" there are plenty of units listed from international sellers for the 848 evo.
Italian Motorcycles in Adelaide have told me they can reflash my ecu (for 1098 streetfighter) for better performance and to delete the closed loop system. Pablo is the service manager there to speak to.
