Is a new CSL Elite wheel & base bundle for PS4 compatible with an older PS3 console for legacy GT5 & GT6 games?
Native support is not available with the CSL Elite for PS4.
To be clear, the CSL Elite + Model is specifically noted for PS4 compatibility. My question is: is this unit also capable of being used on a PS3 console for GT5 & GT6 gaming or is there something about PS4 compatibility that prevents its use with the older console?
It will almost certainly not work. Previously, Fanatec sold PS3 compatible wheels. Sony requires strict licensing and compatibility, so nothing just works out of the box. I think what Joseph was alluding to is that some third party devices may form an emulation layer between the two that would let it work. Search online for something like that if you are interested, but they are not cheap.
