What’s New in v1.21.6

The latest updates and features added to AC EVO FFB Tuner.

New

Multi-Game Support

Full support for RaceRoom Racing Experience and Assetto Corsa alongside AC EVO. Each game has its own isolated FFB pipeline, shared memory reader, and haptic synthesis path. Switch games from a dropdown — pipelines auto-switch.

New

HF8 Haptic Pad Integration

Direct support for ButtKicker HF8 haptic seat pad via the ForceFeel SDK. 8 motor zones, 5 telemetry sources (suspension, slip, kerb, lateral G, engine RPM), per-zone source weight sliders, individual gain & enable, and motor test popup.

New

Live Auto-Tuner

Real-time automatic FFB parameter correction while driving. Monitors average force, peak force, snap events, clipping rate, centre oscillation, and steering jitter. Tick-level and lap-level corrections with cooldown system and logging.

New

Satellite Map View

Mapsui-based ESRI tile overlay with auto-alignment, calibration mode (drag to shift, scroll to rotate), and zoom-to-cursor. Hardcoded GPS for 25+ known tracks.

New

Real Physics Vibration Data

Replaced synthetic sine waves with real AC EVO physics telemetry for all vibration effects. Curb, slip, road, ABS, tire scrub (30–50 Hz), and rear slip warning (12–25 Hz) driven by actual game physics.

New

Dynamic Dashboard & Pop-Out Tuner

Redesigned live telemetry dashboard with splash-screen wheel, responsive signal monitor, and recording indicator. New compact pop-out tuner window for second monitor use.

New

Wet Weather & Tyre Condition FFB

Wet weather FFB processing with tyre compound classification. Tyre condition effects: blowout vibration, pressure loss feel, and suspension damage asymmetry.

UI

Redesigned Profiles & Sidebar

Profiles page redesigned with sidebar browser, track/car grouping, and optional auto-upgrade. Collapsible sidebar with icon-only mode, wider 200px default layout. Per-slider reset buttons and dark-themed tooltips.

Built for Sim Racers Who Demand More

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.

15-Stage DSP Pipeline

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.

10-Band FFB Equalizer

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.

Multi-Game Architecture

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.

The 15-Stage Processing Pipeline

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.

01

Auto-Gain

Car-specific FFB multiplier compensation so every car feels consistent.

02

Channel Mixer

Blend Mz, Fx, Fy tire forces (front + rear) with wheel-load weighting.

03

Normalize + Compress

tanh-based dynamic range compression preserves detail while preventing clipping.

04

LUT Response Curve

Linear, Soft Center, Progressive, and Dead Zone presets.

05

Slip Enhancement

Wheelspin and oversteer amplification to feel tire slip before it becomes a problem.

06

Damping & Friction

Coulomb friction model with angular acceleration inertia for realistic resistance.

07

Dynamic Effects

Cornering, suspension, G-force, and yaw rate forces layered into your signal.

08

Tyre Flex

Carcass deformation and contact patch dynamics from shared memory telemetry.

09

Grip Guard + Stationary Friction

Elastic displacement friction for tyre scrub when stopped. Grip Guard prevents pull-away forces on grip loss.

10

Center Fade

Physics-preserving fade prevents zero-crossing notchiness while preserving Mz curve.

11

Low-Speed Fade

Gradual force reduction below 5 km/h for parking and pit stops.

12

Slew Rate Limiter

Speed-scaled max force change per tick eliminates snap-oversteer spikes.

13

10-Band Equalizer

Parametric biquad EQ from 2 Hz to 100 Hz — shape every frequency independently.

14

Vibration Mixer

Curb, slip, road, ABS, tire scrub, and rear slip warning vibrations mixed in.

15

LFE / Rumble

Suspension travel and RPM-driven low-frequency effects for immersive bass rumble.

Multi-Game Support

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.

Assetto Corsa EVO Primary

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.

Real Physics Vibrations Wet Weather FFB Tyre Condition Effects
RaceRoom Racing Experience Supported

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.

Brake Boost DC Blocker Centre Suppression Grip-Loss Feel
Assetto Corsa Supported

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.

AC Mixer Scales Gear Shift Filter Brake Boost

10-Band FFB Equalizer

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.
