4. New Status: Candidate. Quality Assurance testing. - Test all other cars in set for similar improvements: PASS except Camaro with still ridiculous amounts of centering spring feel. - Test another HQ track with representative car for similar improvements: PASS 3. Problem: Still not happy with road feel through corners. Can't judge how much slip is going on. 3.1 Theory: Try big swings on Force Grip to see if I can tell where it gets better then try to dial it in from there. FFB steer force grip weight="0.35751", 0.25751-> vs 0.45751+>(!?) ^ Continued from Step #2 ^ 0.25751: Completely numb in corners; felt it immediately ^ 0.45751: Felt better, like I needed even more, which seems crazy because it's already a big jump. See if Force Exponent or Grip Factor will help first before coming back here and trying even bigger numbers. 3.2 Theory: Maybe Force Exponent needs to be tightened up (decreased) a bit FFB steer force grip weight="0.35751" ^ Reset from theory above to test Force Exponent FFB steer force exponent="0.89649", 0.79649, 0.69649 ^ Continued from Step #1 ^ 0.79649: Did not bring out cornering forces enough, a little bit maybe but not nearly enough. Did appreciate the higher centering forces, though. ^ 0.69649: Still numb through corners, although high centering forces do seem to provide more info about car trajectory through the corner. Force Exponent + Grip Weight or Grip Factor changes in combination might be something to try out. 3.3 Theory: Maybe Grip Factor needs to be more to the front. FFB steer force grip weight="0.35751" ^ Reset from theory above to test Force Exponent FFB steer force exponent="0.89649" ^ Reset from theory above to test Force Exponent FFB steer force grip factor="0.99998", 0.99999, 1.00000 ^ 0.99999: Slight improvement to cornering road feel; Improvement to steering rack forces during cornering; Noticeably 'later' response in the wheel ffb to the backend getting loose but driveable; Maybe higher Grip Factor + higher Grip Weight could keep steering rack forces high while bringing out cornering road feel. ^ 1.0000: No/little improvement to cornering road feel. Small improvement to steering rack forces during cornering. Even more noticeably 'later' response in wheel ffb to the backend getting loose but still driveable, I think; Best bet might be higher Grip Factor + higher Grip Weight. 3.4 Theory: Try combo of lower Force Exponent, higher Grip Weight, and higher Grip Factor to see if together they make a larger improvement. FFB steer force grip weight="0.35751", (Exp. 1) 0.45751, (Exp. 2) 0.45751, (Exp. 3) 0.45751, (Exp. 4) 0.55751, (Exp. 5) 0.50751, (Exp. 6) 0.53251, (Exp. 7) 0.52001, (Exp. 8) 0.51376, (Exp. 9) 0.51376, (Exp. 9b) 0.51376 + FFB steer force exponent="0.89649", (Exp. 1) 0.89649, (Exp. 2) 0.79649, (Exp. 3) 0.79649, (Exp. 4) 0.79649,(Exp. 5) 0.79649, (Exp. 6) 0.79649, (Exp. 7) 0.79649, (Exp. 8) 0.79649, (Exp. 9) 0.69649, (Exp. 9b) 0.59649 + FFB steer force grip factor="0.99998", (Exp. 1) 0.99999, (Exp. 2) 0.99998, (Exp. 3) 0.99999, (Exp. 4) 0.99999, (Exp. 5) 0.99999, (Exp. 6) 0.99999, (Exp. 7) 0.99999, (Exp. 8) 0.99999, (Exp. 9) 0.99999, (Exp. 9b) 0.99999 ^ Exp. 1: Overall improvement; Improved road feel in cornering; Too much Grip Weight wheel weight loss in hard cornering; ^ Exp. 2: Same road feel in cornering; Less but still too much Grip Weight wheel weight loss during hard cornering; Losing backend quicker; ^ Exp. 3: Improved steering rack forces in cornering that help improve cornering judgement; Less road feel in cornering; ^ Exp. 4: Improved road feel during cornering / A little too much, can decrease Grip Weight; Similar quality steering rack forces as before. ^ Exp. 5: Lost road feel due to less Grip Weight / Although sometimes it feels too much; Maybe some other param change to keep road feel but not too much wheel weight loss? Maybe try Force Exponent after this. ^ Exp. 6: Better road feel but could use less wheel weight loss in corner so lower Grip Weight; ^ Exp. 7: Road feel not as much as I want but wheel eight loss in hard cornering still too much so lower Grip Weight again ^ Exp. 8: Try more laps but if I had to say I think too much wheel weight loss in hard cornering so lower Grip Weight but that means less road feel; Maybe try lower Grip Weight + lower Force Exponent to tighten up what feeling is still there. Actually, just try tightening up Force Exponent - do I get better road feel in cornering? ^ Exp. 9/9b: Little/no improvement to road feel in cornering; Brought back centering spring feel, too. ^ I give up this part. 3.5 Problem: STILL not happy with road feel through corner apex and exit. Difficult to judge how much grip there is. ^ Continued from 3.4 Exp. 8 Theory: Try BIG Grip Weight changes, because I know that does help with corner feeling, and try to bring it back down with Force Exponent and Grip Factor. FFB steer force grip weight="0.51376", 0.81376, 0.66376, 0.58876, 0.55126, 0.57001, 0.560635, 0.5559475, 0.55829125, 0.557119375, 0.5565334375, 0.55624046875 ^ 0.81376: Little/no road feel improvement but improvement in wheel weight feeling during cornering; Guess I'll just have to tune to that now and give up on road feel. FFB steer force exponent="0.79649", 0.89649, 0.84649 2. Problem: Lack of road feel on corner exit. Theory: Decrease Grip Weight to increase effect of road feel through steering rack forces. Not increasing Grip Weight because wheel-weight loss during grip loss feels okay so far. Experiment: FFB steer force grip weight="0.30720", 0.29720, 0.2772, 0.3272+>, 0.3672+<, 0.3472->, 0.3572+>, 0.3622-<, 0.3597+<, 0.35845+<, 0.357825+<, 0.3575125 - Might be feeling centering spring a little too much again. Result: Pending... 1. Problem: Too much centering spring causing clipping; Feels like pushing through numb forces. Theory: Increase Force Exponent to reduce tightness of the wheel around center. Should allow forces to come through once clipping is avoided. Experiment: FFB steer force exponent="0.84649", 0.94649+<, 0.89649 Result: Reduced centering spring, doesn't necessarily feel like pushing through just numb forces anymore. Still need some road feeling, though, but I think that will be Grip Weight related and done in the next step. 0.
