If you want to edit the settings and mapping for the Wheel, run the x360ce.exe program and make and save any your changes then close the program (it should be closed when you play the game unlike pinnacle which needs to run in the notification area). Be sure that the Xbox 360 Controller is off because Toca Edit will detect it and make it your primary controller which then disables the Wheel.
X360ce.exe
I ran the 32-bit version of x360ce.exe in both C:\Program Files (x86)\Steam\steamapps\common\Portal and C:\Program Files (x86)\Steam\steamapps\common\Portal\bin. It created the xinput1_3.dll file in both directories. I fiddled with the permissions of the DLL in the bin directory to prevent it from being overwritten by the game.
Please post back here if anyone finds better settings. Also, adjusting this for the G27 and other wheels should be relatively easy. Download the x360ce.App-2.1.2.191.zip file from and drop the extracted file into your NFS:Rivals folder, launch x360ce.exe and adjust accordingly. Mostly, we will just need the InstanceGUID changed within the INI file and possibly some buttons remapped.
