Forza Horizon 6 Tune Master

Pick a car from the built-in game database, install parts like in the in-game garage, and get an optimized tune instantly. Outputs tire pressures, alignment, springs, ride height, dampers, ARBs, aero, differential, brakes, gearing and

Main Features

• []Built-in game database — all cars and upgrade parts extracted directly from FH6 files. Zero setup, works offline.[/]

  []Install parts like in-game — collapsible upgrade sections mirror the garage:[/]

• []Body kits & modifications — engine, drivetrain and aspiration swaps[/]

  []Engine — camshaft, displacement, valves, pistons, flywheel, intake, manifold, exhaust, fuel system, intercooler, restrictor, ignition[/]

  []Motor & battery — for EVs, with motor swap and upgrades[/]

  []Chassis & handling — springs/dampers, ARBs, brakes, chassis stiffness, weight reduction[/]

  []Drivetrain — gearbox, clutch, final drive, differential[/]

  []Tires & wheels — compound, width, profile, rim style, rim size, track spacers[/]

  []Aero & appearance — front/rear bumpers, rear wing, side skirts[/]

• []7 disciplines: Road, Touge, Rally, Cross Country, Drift, Drag, Street[/]

  []4 seasons: Spring, Summer, Autumn, Winter — grip factor adjusts springs, dampers, ARB, diff and tire pressure[/]

  []Drag distance: ¼ mile, ½ mile, or full mile[/]

  []All tire compounds from the game database[/]

  []Alignment: camber, caster, toe (front and rear)[/]

  []Suspension: spring frequency (Hz), spring rate (N/mm), ride height, bump and rebound damping[/]

  []Transmission: final drive, geometric gear ratios targeting max speed at peak RPM. Recommended gear count with force-recalculate checkbox.[/]

  []Differential: separate accel/decel settings for front, center and rear diff (including AWD)[/]

  []Aerodynamics: iterative downforce calculation accounting for power, speed and drive type[/]

  []Brakes: balance and pressure[/]

  []Tire pressure: adjusted for mass, weight distribution, tire compound, profile and rim diameter[/]

  []Launch control RPM: drag-specific optimal start RPM (accounts for aspiration, torque peak, drive type, fuel)[/]

  []Charts: power/torque curve with peak markers, gear-speed diagram with legend[/]

  []Floating overlay (Ctrl+Shift+O): tune results on top of the game, draggable, resizable, adjustable opacity[/]

  []Profiles: save/load/delete full builds as JSON (%APPDATA%\ForzaTuneMaster\profiles\)[/]

  []Font scaling: +/− buttons (or Ctrl±) adjust text across the whole app including charts. Persisted between launches.[/]

  []Units: Metric / Imperial. Power: HP / PS / kW. Spring rate: N/mm · kgf/mm · lb/in. All calculations in SI — conversion is display-only.[/]

  []Localization: Russian / English (switchable in UI)[/]

  []Dark theme: styled dark-toned UI[/]

  []Changelog: click the version badge to see what's new. Auto-shown on first launch after an update.[/]

  []Built-in help (10-step guide) — opens on first launch.[/]
