Intercept, process, and enhance your FFB signal through a 15-stage DSP pipeline before it reaches your wheel. Now with full multi-game support for AC EVO, RaceRoom, Assetto Corsa, and Le Mans Ultimate.
The latest updates and features across the last two releases.
The app is now distributed under the GNU General Public License version 2 (GPL-2.0-only) with full upstream attribution — Trueforce-For-All (Mhytee) and mescon's logitech-trueforce-linux-driver are credited for the TrueForce stream and HID++ protocol work. A LICENSE file ships with the app and the installer.
Logitech RS50 / G PRO wheel screen shows gear + speed (feature 0x8130, layout J) driven over HID++ while force rides the TrueForce stream. Thread-safe, paced at 2 Hz, returns to its default screen when disabled.
FFB no longer dies permanently when the game grabs the wheel — re-acquires re-bind to the current window handle and escalate to a full reconnect immediately on failure. Wheel LEDs and HF8 stay alive while you check the app mid-session.
The TrueForce stream carrier no longer makes the wheel hum or crunch at 0% force — pump rate halved to the wheel's documented minimum (250 Hz) with a quiet keepalive while idle.
Your wheel is capable of far more than the game sends it. AC EVO FFB Tuner unlocks that potential with a professional-grade signal processing pipeline and multi-game support.
Auto-gain, channel mixing, compression, LUT curves, slip enhancement, damping, dynamic effects, tyre flex, stationary friction, EQ, vibration, LFE rumble, and more — every signal is precision-shaped.
Like an audio EQ for your wheel. Shape forces from 2 Hz steer weight all the way to 100 Hz ABS pulses. Boost road texture, tame kerb strikes — your call.
Isolated FFB pipelines for AC EVO, RaceRoom, and Assetto Corsa. Each with its own shared memory reader, pipeline subclass, and haptic synthesis path — tune one without affecting another.
Every stage is independently tunable. Your physics signal travels through each one in sequence before reaching your wheel. Game-specific overrides add extra stages per-title.
Car-specific FFB multiplier compensation so every car feels consistent.
Blend Mz, Fx, Fy tire forces (front + rear) with wheel-load weighting.
tanh-based dynamic range compression preserves detail while preventing clipping.
Linear, Soft Center, Progressive, and Dead Zone presets.
Wheelspin and oversteer amplification to feel tire slip before it becomes a problem.
Coulomb friction model with angular acceleration inertia for realistic resistance.
Cornering, suspension, G-force, and yaw rate forces layered into your signal.
Carcass deformation and contact patch dynamics from shared memory telemetry.
Elastic displacement friction for tyre scrub when stopped. Grip Guard prevents pull-away forces on grip loss.
Physics-preserving fade prevents zero-crossing notchiness while preserving Mz curve.
Gradual force reduction below 5 km/h for parking and pit stops.
Speed-scaled max force change per tick eliminates snap-oversteer spikes.
Parametric biquad EQ from 2 Hz to 100 Hz — shape every frequency independently.
Curb, slip, road, ABS, tire scrub, and rear slip warning vibrations mixed in.
Suspension travel and RPM-driven low-frequency effects for immersive bass rumble.
Select your game from a dropdown — the app automatically switches to the correct shared memory reader, FFB pipeline, and haptic synthesis path. Each game pipeline is completely isolated.
Full 15-stage DSP pipeline with real AC EVO physics telemetry. 333 Hz input, all vibration effects driven by actual game physics. Wet weather FFB processing with tyre compound classification.
Dedicated R3E pipeline with brake weight-transfer boost, DC blocker, dynamic suppression, and V-shape centre suppression. Adaptive gear shift filter and grip-loss feel for understeer detection.
AC-specific pipeline with custom mixer scales tuned for synthesized force data. Gear shift filter, configurable brake boost, and simplified pipeline for AC lower-fidelity telemetry.
Dedicated LMU FFB pipeline with 20+ extended telemetry fields from shared memory. Player telemetry offset via header playerIdx (not scoring index). Full wheel array with suspension, forces, tire data.
Think of it as an audio equalizer for your steering wheel. Boost the frequencies you want to feel more, cut the ones you do not. Each band supports -12 dB to +12 dB gain with dynamic heat-map colors.
Additional tools and features that make AC EVO FFB Tuner a complete sim racing force feedback solution.
Real-time FFB correction monitoring average force, peak force, snap events, clipping, oscillation, and jitter. Tick-level and lap-level corrections with cooldown system.
Mapsui-based ESRI tile overlay with auto-alignment, calibration mode (drag/rotate), zoom-to-cursor, and GPS for 25+ tracks. Popout overlay for second-screen use.
Records track layout from car position. Auto-detects corners and sectors. Force heatmap overlays for snap events, oscillations, and clipping. One-click tuning recommendations.
Direct ButtKicker HF8 integration via ForceFeel SDK. 8 motor zones, 5 telemetry sources, per-zone source weights, individual gain/enable, master gain, motor test popup.

RPM shift lights, ABS flash, and race flag indicators. Supports Moza, Fanatec, Logitech, and Simucube with configurable brightness and color schemes.
AI-powered FFB tuning assistant with live telemetry analysis. Chat interface provides real-time suggestions, explains pipeline behavior, and manages pending changes. Scope-bound prompts prevent off-topic questions.
Manage Race Info, Telemetry, and other screen overlays from a dedicated page. Runtime game detection auto-switches pipelines. Discord Rich Presence and OBS streaming overlay support.
JSON-based profiles for all settings. Sidebar browser with track/car grouping. Save, rename, export, import. 7+ pre-configured baselines included.
