7. Problem: Sharp increase-then-decrease over bumps feels like skipping over bumps

Theory 1: Increase Force Exponent to spread out forces over wider area so 'sharp knife edge' forces 'spread out'

Experiment:

FFB steer force exponent="0.75149", 1.0+>, 1.49702+<, 1.24851+<, 1.124255+> (1), 1.1863825+<, 1.15531875...
1. At this point, I still feel the issue and I'm not sure this parameter can solve it; maybe it's Grip Weight related

Result: Initial adjustments were a big improvement but didn't help the problem as much as I was hoping. Try Theory 2...

Theory 2: Decrease Grip Weight to increase wheel weight from steering forces to reduce wheel weight loss

FFB steer force grip weight="0.32362", 0.31362+

Result: Didn't give any improvement and I don't think it will improve much.

6. Problem: Steering too heavy

Theory: Decrease Steer Force Output Max which will reduce the strength of forces from the steering rack.

Experiment:

FFB steer force output max="0.72969", 0.71969+<, 0.69969+<, 0.65969+<, 0.57969+<, 0.41969+>, 0.49969...

Result: Much better

5. Quality Control:

- Race Weekend: Zolder 2005, AI 108, finished 2nd, avg lap times high 1:36s

- Championship:
  - Zolder 2005, AI 108, Q3, P1
  
4. Experiment: Check increased Grip Weight feeling; I just want to try it out and see how it feels because I've managed to tune the whole car without Grip Weight and Grip Factor and it feels weird, like I left something out.

FFB steer force grip weight="0.30720", 0.40720+<, 0.3572+<, 0.3322+<, 0.3197+<, 0.31345+=
- 0.40720: Better but too much; Had more expressive wheel weight loss in cornering due to grip loss which is a good thing, just a little too much of it.
- 0.3572: Better, maybe just a little less
- 0.3322: Nice, just a bit lesss
- 0.3197: ~
- 0.31345: Feel about right

3. Problem: Forces way too strong; Not clipping, it just feels overly strong for street-style cars;

Theory: Try lowering Output Max, maybe

FFB steer force output max="1.80000", 0.9+>, 1.35+=
- 1.8: Too strong for these types of cars; Not clipping but too strong;
- 0.9: Better but now too weak;
- 1.35: About right, not sure if up or down so will leave it for now.

2. Problem: Centering spring feel; Tight/somewhat jittery wheel around center on straights; Grip levels not coming through in corners.

Theory: Increase Force Exponent to expand force range so that it's not as compressed around center. This should reduce centering spring feel, reduce tight/jittery center, and help reveal grip levels by avoiding compressing it all around center.

FFB steer force exponent="0.84649", 0.94649+>, 1.14649+>, 1.54649+<, 1.34649+<, 1.24649+<, 1.19649+<, 1.17149+<, 1.15899+<, 1.15274+>, 1.155865+<, 1.1543025->, 1.15508375...
- 0.94649: Improved but similar symptoms as above.
- 1.14649: Still feel centering spring; Tightness/jitter around center solved; Grip levels improved but could be better;
- 1.54649: Still feel centering spring, maybe can't solve it here; Tightness/jittery around center gone; Grip levels improved again.
  ^ Remember: Not centering spring if detail still present in high speed corners
- 1.34649: Improved but similar symptoms as above.
- 1.24649: Now just trying to keep this as low as possible to retain detail but avoid centering spring and tightness/jittery around center on straights;
- 1.19649: ~
- 1.17149: ~
- 1.15899: ~
- 1.15274: Possible centering spring returning; Maybe do one more step, then move on to Grip Weight to see if it can help reveal grip levels while cornering...
- 1.155865: Tiny looseness/sway around center;
- 1.1543025: Felt like I lost some detail;
- 1.15508375: Can't feel anything else wrong with it; Still way too strong forces, though.

...





1. Initial observations:

- How does FFB feel? Centering spring feel; Tight/somewhat jittery wheel around center on straights; Grip levels not coming through in corners; Road feel actually okay.

- Do all/most cars share similar FFB experience? Yes

- Other issues: Tire heating/cooling problems, inability to keep tires warm;

24. Get some 'wheel goes light when losing grip' back
    ^ DTM Classics 1992, BMW M3 E30, Zolder 2005
	
*** CAUTION: Step #23 was acceptable for car control and handling. If I find I'm losing control after this step then I should probably just go back and stop adjusting stuff. Also, I'm testing this on DTM Classic Mod BMW e30 and not the HQ Ferrari F575. So it's getting a little dicy at this point.
