Configure realfeel to use max damper (right CTRL KP5), set realfeel mix to 60-70 (if using LeoFFB in combination, which is recommended), set smoothing to 3, and max force to 2500~ (or -2500 as some mods require). I don't remember how good Enduracers LMP2 is with realfeel; some mods work poorly with realfeel, but most work well. The above settings are an excellent baseline to start with for all rfactor mods for CSR/CSR Elite users. Tested and work well with F1 1979, F1 1991HE, DRM Revival 2.0, FSONE 2008/2009, MMG 2007, and many others. I use FFB level 60 on my CSR, which is good and strong but not overpowering. Make sure your centering spring is activated in Fanatec driver (most recent driver/firmware combo removed this option, thus doesn't work for rfactor -- I flashed and had to revert), and also make sure the SPR spring setting on your wheel is either -1 (for old firmwares) or 0 (for newer firmwares) and the wheel damper, drift settings, etc, are disabled. Also rfactor itself has to be FFB on "Low" setting. I'm probably forgetting some details even, there's so many to remember...
Also try these controller.ini settings (backup controller.ini first):
