Record a baseline before moving sliders
Write down exact car year/edition, stock class, fitted parts, tune, assists, input device, game build and route. Save the original tune in the game if available. Stock PI from the official list describes an entry, not the performance of your upgraded car. Use class checks to avoid comparing different editions.
One change, one question
| Observed problem | Controlled comparison | Keep a note of |
|---|---|---|
| Unstable entry | Same corner, approach speed and braking point; compare original setup with one change | Entry speed, missed apex and recovery |
| Weak exit | Same gear and throttle approach; restore baseline between different changes | Exit line and repeatable time |
| Rough-road loss of control | Same rough section, weather and car | Landings and missed checkpoints |
| Wheel feels heavy or oscillates | Return hardware/game controls to defaults before changing car tuning | Feedback clipping, centering and physical rotation |
This table is an editorial experiment design, not a guarantee that one specific slider causes the symptom. The official wheel guide concerns input and force feedback; it is not a source for a universal camber, differential or tire-pressure tune.
A compact log that remains interpretable
Use columns: baseline, single change, conditions, three valid results, recovery failures and decision. Repeat both versions if conditions vary. If a new part changes the class, recheck event eligibility before keeping it. Do not compare a clean run to one with a rewind and claim the setup alone caused the difference.
Know when to stop
Keep the baseline if results do not separate consistently or the change makes the car harder to control. There is no independently measured FH6 universal slider sheet on this page. For graphics, use the benchmark plan; for wheel hardware and deadzones, use wheel settings.
