If your talking about ffb, providing that there is a firmware 737 for the CSW (as i have the CSR-E) i would use that as it is the latest one before they started decreasing the maximum ffb force of the motors and i can feel the details much much better on that firmware. If you do try it, just make sure you make a note of your current firmware so you can always revert back in it's not for you. In-game i use an ffb smoothing value of "0". That's about it.
