I've never looked at the FFB type in the game config for Le Mans personally. Off the top of my head, I recall seeing Spindizzi mentioning something, in one of the Supermodel threads, along the lines of the official rom for FFB in Le Mans being the same as the one in Sega Touring Car for the Model 2 Board, but when he tried swapping it into the Le Mans ROM, it didn't do anything, hence the use of the Scud Race FFB rom.
