I think the key is to use a bit lower gain if you find a flat feeling. The engine effect seems fine at fx 50 for the tm500. I didnt want to reduce FX because some flat curbs are using a rumble effect, and I want to preserve that. Also Im not sure the engine is an FX really. If I understand its part of the raw ffb that is based on engine rpm. I might be noteworthy to point out my TM control panel settings. 80/100/100/0/20 Strength/Constant/Periodic/Spring/Damper It must be said that the ffb and the gain/lfb setup is very hardware sensitive. If you're a DD wheel user you likely should not be using low force boost, you dont need it. The Logi and TM users are definitely getting different mileage from the profiles/settings. Its a work in progress for sure. I have no doubt that in the end the ffb will be second to none, but in these early days the ride is going to have its ups and downs.
