If you own a Simucube, you will eventually notice that your “perfect” settings in one sim can feel wrong in another. That’s normal. Different sims output force feedback differently: update rate, scaling, kerb detail, and how they handle self-aligning torque all vary.
This guide shows a repeatable profile workflow for Simucube so you can switch between iRacing, ACC, Automobilista 2 and Assetto Corsa without re-inventing the wheel each time.
One base profile, then small “sim profiles”
The easiest way to stay consistent is to create:
- Base profile: your preferred steering feel (damping/friction/inertia) and safety limits.
- Sim profiles: small adjustments for smoothness and harshness per sim.
What changes most between sims
| Sim | Typical feel | What you usually adjust |
|---|---|---|
| iRacing | Clean, informative, can feel light if not set correctly | Strength scaling, avoid clipping, minimal smoothing |
| ACC | Kerbs can be harsh, heavy GT steering, strong road texture | Smoothness, kerb harshness control, avoid oscillation |
| AMS2 | Can feel lively and detailed, varies per car | Damping and reconstruction balance |
| Assetto Corsa | Very tunable, depends on mod/car quality | Baseline consistency and per-car strength |
Baseline structure you can copy
Profile A: “Clean competitive”
Use for iRacing and most sprint racing. Goal: maximum detail with minimum artificial weight.
Profile B: “Endurance smooth”
Use for long stints, bumpy tracks, or when you want less fatigue.
Profile C: “Kerb control”
Use for sims/cars where kerbs feel sharp. Goal: reduce the spike without killing road feel.
Example adjustments (small, on purpose)
| Change | Why | Use it when |
|---|---|---|
| Reconstruction +1 | Reduces grain without changing physics detail too much | Low update-rate feel or “sandpaper” steering |
| Damping +2–5% | Stabilises without heavy steering | Oscillation on straights |
| Torque bandwidth slightly lower | Removes high-frequency kerb buzz | Kerbs feel like shocks instead of texture |
| Slew rate limit low | Softens abrupt spikes | Bumpy tracks, rally, harsh curb strikes |
Why your cockpit matters for profile consistency
If your mounting changes (even slightly), your “perfect profile” changes. A rigid aluminium rig gives you a stable reference point, which makes tuning faster and more repeatable.
SIMGASM setup that supports profile switching
- Stable base: SIMGASM Sport (C120) or SIMGASM Pro (C160)
- Keep peripherals in reach: universal peripheral deck for button boxes and dashboards
- Clean workflow: PC tray for quick adjustments and pit menus
Per sim checklist (what to set before you touch filters)
iRacing checklist
- Set the correct wheel force value for your wheelbase class (so the sim scales forces properly).
- Use linear mode so forces scale predictably.
- Use the auto FFB feature per car as a starting point, then reduce a little if you see clipping.
- Keep “extra” effects low: let physics do the talking.
ACC checklist
- Start with a conservative gain and watch for clipping in heavy corners and kerb hits.
- Turn down “road effects” if you want cleaner steering information.
- If kerbs are harsh, try a small TrueDrive smoothness adjustment before you reduce in-game gain too much.
AMS2 / Assetto Corsa checklist
- Confirm rotation is correct and that soft lock behaves as expected.
- Test a known “reference car” first so you can judge changes reliably.
- When using mods (AC), expect that some cars simply output noisy FFB. Don’t chase perfection with filters.
Branch your profiles by car class, not by mood
Instead of having 12 random profiles, use 3–4 purposeful ones:
- GT / endurance: slightly calmer, less fatigue, stable on kerbs.
- Formula: faster transitions, less inertia, crisp centre feel.
- Rally / bumpy tracks: control spikes with mild slew-rate/bandwidth, keep hands relaxed.
Make it repeatable: a micro change log
Every time you change a setting, write one line in the profile name or notes: “+2% damping”, “RF 3 → 4”. It sounds boring, but it turns tuning into progress.
Build stability into the rig so profiles stay consistent
If your wheel deck or pedal platform shifts over time, the same TrueDrive settings will feel different week to week. Aluminium profile rigs make it easy to re-align and re-tighten without permanent modifications.
- Seat comfort helps you judge FFB: Core Recline seat (comfort) or Atlas GT (locked-in).
- Clean wiring improves reliability: use service loops and strain relief.
