Water temperature HUD in LocalCarData, AMS2 DSX/mapper support, DSX and ACC fixes

[aaronfang]

What changed

Data and game adapters

• LocalCarData: Add engine coolant (water) and oil temperature fields for overlays.
• Richard Burns Rally (RBRDataProvider): Map relevant temperatures from Kelvin to Celsius for consistency with other titles.
• Automobilista 2 (Mapper): Compute signed slip ratio per wheel from wheel speed and ground speed; fix longitudinal acceleration unit conversion (m/s² → g).

New overlay

• WaterTemperature: New overlay with configurable font, threshold-based coloring, and Celsius/Fahrenheit unit selection (WaterTemperatureConfiguration + WaterTemperatureOverlay).

DSX

• Shared DSX (Race Element.HUD.Common): AMS2 support including signed slip handling;
• extract CalculateFrequency helper;
• add InvertFrequency for brake and throttle.
• Bugfix: AddCustomAdaptiveTriggerToPacket no longer overwrites the valueMode argument (DsxPacketExtensions / DsxOverlay and related call sites).
• ACC-specific (Race_Element.HUD.ACC): Fix operator precedence for averageRearTyreSlip so the expression evaluates correctly.

Files touched (high level)

• Race Element.Data/Common/SimulatorData/LocalCar/LocalCarData.cs
• Race Element.Data/Games/Automobilista2/DataMapper/Mapper.cs
• Race Element.Data/Games/RichardBurnsRally/RBRDataProvider.cs
• Race Element.HUD.Common/Overlays/Driving/DSX/* ( and new WaterTemperature/* )
• Race_Element.HUD.ACC/Overlays/Driving/DSX/TriggerHaptics.cs

Suggested checks for reviewers

• AMS2: Verify per-wheel slip sign and DSX trigger behaviour (including reverse / opposite slip).
• RBR: Confirm coolant temperatures match expectations versus other readouts.
• ACC DSX: Compare rear-slip-driven haptics before/after the precedence fix under similar conditions.
• Water temperature overlay: Threshold colours and ℃/℉ switching.

[RiddleTime]

Most looks good except some data modification that should happen within the data provider of AMS.

[RiddleTime]

This should be within the data provider.

Same here, this should be within the data provider. Handle negative slip ratio values there.

Thanks for the review! I've addressed both points:

Changes made:

1. AMS2 Data Provider (Race Element.Data/Games/Automobilista2/DataMapper/Mapper.cs, line 168-174)

   • Modified to return absolute slip ratio values using Math.Abs() for consistency with other games

2. DSX TriggerHaptics (Race Element.HUD.Common/Overlays/Driving/DSX/TriggerHaptics.cs)

   • Removed game-specific logic from HandleBrakingGeneric (previously line 40-63)
   • Removed game-specific logic from HandleAccelerationGeneric (previously line 110-133)
   • Now uniformly handles absolute slip values from all data providers

The signed slip handling is now properly contained within the AMS2 data provider, and the HUD layer no longer needs to know which games use signed vs unsigned slip ratios.

Let me know if there's anything else that needs adjustment!
