Ok, Got ia Logitech G27 to work with x360ce. This just worked for me.
I used x360ce in it's own DIR setup the wheel the way I like it (creating xinput1_3)
put the 3 files in the c:\Sega\Daytona directory
Renamed Xinput9_1_0.dll
Renamed Xinput1_3 to xinput9_1_0.dll (the file daytona is expecting)
Played a race on the Daytona track came in 1st place (but only 4th in high scores)
Works.
