Will my wingman formula force gp work with grid on the ps3?

Highly unlikely.It is not a Sony licensed product and Logitech often causes more problems with all systems.I worked on Nintendos and Sony PS2's and know for a fact that there are no other items which are licensed by either.To get the official licensing,they have to pay a fee in order to build to the exact specifications required by both.Since they do not,they are not allowed to use the exact voltages,size of controller inputs,and many other things which really should be exact.I saw at least one unlicensed product such as this cause problems every day for 3 years straight.Stick with the game console name brand products and you will be much better off.Good luck,Greg
