Dyno+ 3.0

A lightweight HUD app that turns any vehicle into a rolling dyno and configurable vehicle diagnostics dashboard.

Dyno+ displays live horsepower, torque, mass, power-to-weight, force readings, speed, RPM, gear, coolant/oil temperatures, turbo data, exhaust flow and acceleration-run results.

If the HUD cuts out at the bottom, follow the layout guide below:

1. Open HUD Apps.
2. Select Edit Layout, the button looks like a pen.
3. Click on the Dyno+ app.
4. Click and hold the bottom orange resize handle.
5. Drag the handle downward until the full app is visible.

Features

• Power — engine output in horsepower and kilowatts.
• Torque — live engine torque in Nm or lb-ft.
• Mass — current vehicle weight in kg or lb.
• Power-to-Weight — live HP per kg or HP per lb.
• Peak Force — highest force produced during the current session.
• Net Force — live chassis force calculated using F = m × a.
• Average Force — rolling 10-second average of net force.
• Speed / RPM / Gear — live drivetrain readouts.
• Coolant Temperature — displayed in °C or °F when a valid running-engine reading is available.
• Oil Temperature — displayed in °C or °F when available.
• Turbo Boost — live turbo boost telemetry when exposed by the vehicle.
• Turbo RPM — live turbocharger RPM when available.
• Exhaust Flow — live exhaust-flow telemetry when available.

Run Lab
Dyno+ v3.0 adds a dedicated Run Lab popup so the main dashboard remains compact.

The Run Lab includes:

• Run start and stop controls.
• Optional configurable countdown:
  • Disabled
  • Custom countdown duration
• Live acceleration milestone progress.
• Run limits for:
  • Maximum RPM
  • Maximum speed
  • Maximum time
  • Maximum distance
• Stop on throttle lift.
• Stop when acceleration ends.
• Wheel speed or air speed selection.
• Completed run details.
• Power and torque graph.
• Peak power and torque results.
• Peak boost.
• Acceleration milestone times.

Acceleration targets use fixed unit-specific milestones:
Metric: 0–100 km/h 0–200 km/h 0–300 km/h
Imperial: 0–60 mph 0–120 mph 0–200 mph

Dashboard customization

• Metric / Imperial Units — persistent unit-system toggle.
• Configurable Dashboard — show or hide dashboard sections through the in-app settings menu.
• Persistent Settings — unit preferences and visible dashboard sections are saved automatically.
• Temperature Warnings — elevated and critical coolant/oil readings receive amber or red warning accents.
• Red Tertiary Theme — muted red accents are used for peak values, buttons, settings, warnings and critical readings.
• Transparent UI Background — designed to remain visible while keeping the game world readable behind the app.

Unit Systems
km/h or mph Nm or lb-ft kg or lb HP/kg or HP/lb N or lbf °C or °F

Installation
Download the ZIP file and place it in the game’s mod folder:
%localappdata%\BeamNG.drive\mods
When launching BeamNG.drive through Steam, you can also open the user folder through:
Manage User Folder → Open User Folder
This option appears after clicking the Play button in Steam.

Usage

1. Launch BeamNG.drive.
2. Open the HUD Apps menu.
3. Add the Dyno+ app.
4. Click the Metric/Imperial button to change unit systems.
5. Click the ⚙ settings button to show or hide dashboard sections.
6. Click RUN LAB to open the run-testing window.
7. Open LIMITS inside Run Lab to configure run behavior.
8. Use Edit Layout to resize the app if necessary.

Notes & limitations

• Dyno+ is read-only. It only displays vehicle data and does not modify vehicle behavior.
• Data availability depends on the vehicle. BeamNG vehicles do not all expose the same sensors.
• Coolant and oil temperatures remain unavailable while the engine is off or while BeamNG only reports startup values.
• Intake-air temperature and battery voltage are not displayed unless the vehicle exposes reliable corresponding signals.
• Dyno+ does not substitute unrelated values such as airflow or electrical load for missing temperature or voltage readings.
• EGT, turbo temperature and transmission temperature are not displayed as generic values because BeamNG does not expose them consistently across all vehicles.
• Average Force requires approximately 10 seconds of driving to fill its rolling window.
• Peak Force resets when changing vehicles, resetting or respawning.
• Run results depend on the telemetry exposed by the selected vehicle.
• Turbo and exhaust readings may remain unavailable on naturally aspirated vehicles or vehicles without exposed turbo telemetry.
• The app is still in beta and may require layout adjustment depending on the selected dashboard size.
• Run Lab is designed to be used through its popup window so the main dashboard remains compact.
