To save u some time and sum it all up, the ECU of the F-Sport is to stiff up the steering wheel while driving like all GS400 model, the steering on that GS400 are stiff accurate during high speed driving which I like it. I read through this ECU of an IS model and that pretty much my conclusion. I don't know how stiff on the IS when changing out to 2011 F-Sport ecu, cus I have not done one yet. I might in the future. If u do, pls let me know. Good luck

Definitely upgrade if you can afford it, or just get coilovers; the change in suspension definitely stiffened up everything for me when I did.
