Forza Styled Speedometer

Overview

A fully customizable Forza Horizon 5-style speedometer for GTA V. The needle moves when you start the engine, follows your RPM smoothly, vibrates when you hit the rev limit, and shows your speed clearly.

Driving assists like ABS, Traction Control and Launch Control work in the background and blink on the gauge when active. You can change all settings from the in-game menu by pressing F11.

What's New in v1.3

New Features

• Dynamic RPM gauge tiers from 7,000 to 11,000 RPM to dynamically match individual vehicle redlines.
• IKT's Manual Transmission support: Seamlessly switch the gear data source between native Game detection and IKT's.
• Turn indicators: Added left, right, and hazard light signals with a toggle to enable or disable them.
• Manual engine start audio: Added support to use the native engine start audio during manual engine start.
• Interruptible ignition sweep: You can now start the engine immediately without waiting for the gauge sweep to complete its full rotation.
• Reset to Default: Quickly restore your HUD configuration values to their factory settings.
• Custom license plate: Optional setting configurable directly through FSS.ini.

Improvements

• Refined ABS and TCS intervention behaviour and reorganized their assist modes.
• Launch Control is now processed internally by the script and no longer requires separate modes in the menu.
• Corrected ABS brake-light behaviour so brake lights illuminate normally while braking, even when ABS is active.
• Improved Center Hub and gear indicator redline syncing across all supported RPM tiers.
• Smarter vehicle-state handling: Parked vehicles remain off by default, while NPC-stolen vehicles stay active.
• Enhanced overall layout handling and configuration stability for the HUD.

Stability & Known Limitations

• Extensively Tested: This build has undergone prolonged gameplay testing (high-speed driving, hard braking, rapid acceleration, engine cycling, menu usage) across both GTA V Legacy and GTA V Enhanced editions.
• 8-Speed Transmission Skip (Limitation): On some upgraded 8-speed vehicles, GTA V's native gear detection may skip 7th gear (jumping from 6th to 8th, or 7th showing briefly for 0.5s). This is a native game limitation rather than a speedometer issue. It is recommended to use IKT's Custom Gear Ratio as a workaround for affected vehicles.

Requirements

• Script Hook V
• Script Hook V .NET

Driving Aids

Assisted Braking System (ABS)

Helps you brake with better feedback when driving fast. Slim mode gives a little help. Aggressive mode helps you stop as fast as possible.

Launch Control (LC)

Stops your tires from spinning when you accelerate from a dead stop, helping you launch faster and smoother.

Traction Control System (TCS)

Reduces engine power when your wheels start to slip to keep you in control. Sport mode lets you slide a little bit. Aggressive mode stops you from sliding almost immediately.

Settings File Guide
