GR RaceControl

Race Intelligence by GermanRacers

GR RaceControl is here

GR RaceControl brings a real race engineer directly into Assetto Corsa Competizione.

It combines live telemetry, a fully configurable in-game overlay, pit stop strategy, tyre and fuel calculations, and team communication in one application.

Most importantly: GR RaceControl is free.

You do not need to race on GermanRacers servers. Use RaceControl for GR events, external leagues, public servers, private sessions, or single-player racing.

Your race. Your data. Your decisions.

While you drive, GR RaceControl processes the ACC live data that is actually available. Fuel usage, pace, fuel level, tyres, weather, traffic, and session progress constantly change — so your strategy should change with them.

No invented live data. No static race-start calculation.

When data is available, it is processed. When it is not, RaceControl makes that clear.

The fully configurable in-game overlay

Build your own race-screen layout. Every overlay module can be moved and resized in Edit Mode — ideal for a single monitor, ultrawide, triple screens, or a dedicated overlay display.

Available modules:

• Driver, RPM, gear, and speed
  
  
• Lap timing, delta, sectors, personal best, and session best
  
  
• Relative gaps, position, and live leaderboard
  
  
• Fuel level, fuel per lap, range prediction, and fuel-saving targets
  
  
• Tyre pressures, tyre temperatures, brakes, and tyre sets
  
  
• Session status, time remaining, air and track temperature
  
  
• Flags, incidents, radar, and input telemetry
  
  
• Track map, minimap, vehicle information, and damage status
  
  
• Weather and rain trend

Use hotkeys to show or hide the overlay, enter Edit Mode, or hide it immediately whenever needed.

Pitstop Manager – strategy that evolves with the race

The Pitstop Manager does not simply calculate a starting fuel amount. It adapts to the race as it unfolds.

• Current fuel level and rolling fuel-per-lap calculation
  
  
• Remaining range and required fuel
  
  
• Stint length, pit windows, and the latest safe pit lap
  
  
• Mandatory stops, tyre changes, and driver swaps
  
  
• Safety reserves and fuel-saving targets
  
  
• Weather trend and tyre recommendation
  
  
• Three strategy variants: Safe, Balanced, and Aggressive

Every completed lap provides new data. RaceControl uses it to calculate the next useful decision — because the strategy that was right at the start may be wrong ten minutes later.

Fuel & Tyres

Plan before the race or import your ACC live data directly into the calculation.

• Required start fuel with a safety reserve
  
  
• Fuel range and stint planning
  
  
• Refuelling amounts for planned stops
  
  
• Fuel-saving calculation
  
  
• Tyre pressure corrections based on real hot-pressure samples
  
  
• Consideration of tyre compound, track conditions, and weather

Team Caller

For sprint and endurance teams, RaceControl includes the optional Team Caller.

Create a PIN-protected team room and synchronize driver order, readiness, strategy variants, and pit calls across multiple RaceControl installations.

It works for GermanRacers events as well as external servers and private leagues.

Built for the entire ACC community

GermanRacers events, news, and live servers are integrated directly into RaceControl. However, the tool is not limited to GR servers.

GR RaceControl is made for every ACC driver.

Many features that are locked behind premium subscriptions in other ACC companion tools are available here for free. We want every driver to have access to useful live information and real strategy support.

By racers, for racers

GR RaceControl is developed together with the community.
