Hi, you can now test this GP2Lap mod.
It comes preinstaled with the 2026 teams, logos, colors and drivers, but I urge you to try the Editor to load your GP2 team/driver roster and modify Logos, colours and numbers.
I have tested it with both an original and a modified version of GP2.

GP2Lap F1 HUD v0.22 adds modern Formula 1 graphics directly inside Grand Prix 2.
The HUD is rendered natively by GP2Lap. It does not require OBS, React, Node.js, Electron or a browser window while the game is running.
Main features

- Support for the 26 drivers selected by GP2 for the race
- Custom driver names, abbreviations and racing numbers
- Custom team names and colours
- External team logos
- Race and qualifying towers
- Driver and timing cards
- Track maps
- Sector and microsector information
- Configurable fuel drain function
1. Back up your current installation
Before installing v0.22, make backup copies of:
Also preserve your existing
SEASONS folder if you already use custom logos.
2. Extract the v0.22 package
Extract
GP2Lap-F1-HUD-v0.22.zip into a temporary folder.
The main files are:
Code: Select all
GP2LAP.EXE
EDITOR.html
GP2LAP.CFG
README.txt
Copy the following files into the Grand Prix 2 folder where your current GP2Lap installation is located:
Replace the previous versions when prompted.
If you already have a customized
GP2LAP.CFG, do not replace it with the example included in the package. The included CFG is only a starting point for new installations.
3. Open the HUD Editor
Open
EDITOR.html with a modern browser such as Chrome, Edge or Firefox.
The editor works locally. It does not upload your files and it does not modify GP2.EXE.
The editor includes:
- Teams and logos
- Drivers
- Import GP2.EXE
- Open CFG or saved project
- Save project
- Export ZIP
4. Import GP2.EXE
Click
Import GP2.EXE and select the executable used by your installation.
The editor reads:
- Team names
- Driver names
- Driver CarId values
- Team and driver order
It automatically detects whether the executable contains:
or:
After importing, review the names, abbreviations, racing numbers and team assignments.
Importing the executable only reads its information. The editor does not write anything into GP2.EXE.
5. Configure the teams
Open the
Teams and logos section.
For each team, you can edit:
- Team name
- Team colour
- Identification mode
- Custom logo
Team names are automatically converted to uppercase when the configuration is exported.
The available identification modes are:
- Built-in logo for this slot
- Custom logo
- Colour only
The fourteenth team does not have a built-in logo. It must use either a custom logo or its team colour.
6. Import a custom logo
Click
Import image under the corresponding team.
The editor accepts common image formats such as PNG, JPEG, WebP and SVG.
It will:
- Crop transparent margins if that option is enabled.
- Resize the image to the native HUD logo size.
- Convert it into the format used by GP2Lap.
- Display a preview of the converted logo.
Use the stroke strength control if the converted logo becomes too thin or difficult to read.
Click
Use logo to apply it.
The native team logo is only 16 × 12 pixels. Simple versions of team emblems usually produce the clearest result.
7. Configure the drivers
Open the
Drivers section.
Each driver has the following fields:
- CarId
- First name
- Last name
- Three-letter abbreviation
- Racing number
- Team
- Drain fuel selection
The
CarId links the HUD entry to the corresponding driver inside GP2. It must be unique and remain between 1 and 40.
When GP2.EXE is imported, the editor fills these values automatically. They should only be changed if your executable or car set uses a different mapping.
8. Select a season folder
Enter a name in the
Season folder field.
For example:
Custom logos will be exported to:
The individual files will be named:
Code: Select all
TEAM01.F1L
TEAM02.F1L
TEAM03.F1L
...
TEAM14.F1L
Use only letters, numbers, underscores or hyphens in the season folder name.
9. Using the Drain Fuel function
The
Drain Fuel function was added mainly for seasons that contain fewer than 13 teams.
GP2 normally expects a full field, so some historical or fictional car sets may need additional filler cars. These cars can remain in the entry list even when they are not meant to participate in the actual race.
The fuel drain function provides a way to make selected filler cars run out of fuel after the session has started.
It can also be used to test:
- Car retirements
- HUD retirement states
- Cars stopping on the circuit
- Incident behaviour
- Future Safety Car logic
To configure it:
- Open the Drivers section.
- Enable Drain for every filler car you want to remove from the running order.
- Enable the fuel drain function.
- Set how long the fuel should be held at zero.
- Export and install the new configuration.
- Start a live GP2 session.
- Press 7 when you want to activate it.
GP2Lap sets the selected cars’ fuel to zero and keeps it at zero for the configured duration.
The duration uses simulation time. Pausing the game pauses the timer, while accelerated time makes the configured period pass faster.
The previous fuel quantity is not restored when the timer ends. The affected cars should eventually stop or retire according to GP2’s normal behaviour.
The function is disabled by default and only affects the CarId values selected in the editor.
This does not remove the filler cars from the entry list or starting grid. It provides a controlled way to retire them after the race or session has begun.
10. Save the editor project
Use
Save project if you want to continue editing the season later.
The project file preserves:
- Driver information
- Team information
- Colours
- Configuration options
- Fuel drain selections
- Converted logo pixels
The project file is used only by the editor. GP2Lap does not read it directly.
11. Export the configuration
Click
Export ZIP.
The editor creates:
The ZIP contains:
Code: Select all
GP2LAP.CFG
SEASONS/
└── LOGOS/
└── <season>/
├── TEAM01.F1L
├── TEAM02.F1L
└── ...
Only teams using custom logos will have an .F1L file.
12. Install the exported configuration
Extract
GP2-HUD-config.zip directly into the Grand Prix 2 folder, beside
GP2LAP.EXE.
Allow it to replace
GP2LAP.CFG when prompted.
Keep the exported folder structure intact:
Code: Select all
GRAND PRIX 2/
├── GP2.EXE
├── GP2LAP.EXE
├── GP2LAP.CFG
├── EDITOR.html
└── SEASONS/
└── LOGOS/
└── 2026/
├── TEAM01.F1L
└── TEAM14.F1L
If the
SEASONS/LOGOS structure or season folder name is changed, GP2Lap will not find the custom logos.
13. Restart GP2Lap
Configuration changes are loaded when GP2Lap starts.
Close the game completely and start it again using your normal GP2Lap launch method.
Changing GP2LAP.CFG while the game is running will not update the active HUD.
14. HUD controls
- 3 — Show or hide the race or qualifying tower
- TAB — Cycle through the race tower information modes
- 4 — Show the timing card and switch between sectors and microsectors
- 5 — Show or hide the selected driver card
- 6 — Show the map and switch between its available views
- 7 — Activate fuel drain for the configured cars
The displayed information changes according to the session and camera:
- TV view can display the complete classification.
- Onboard view displays a compact five-driver window.
- Qualifying and practice use lap times and gaps.
- Race sessions use positions, intervals and the selected TAB mode.
15. Using 14 teams and 28 qualifying drivers
With an original or modified GP2.EXE, all 28 drivers can participate in qualifying.
The HUD reads the qualifying classification by CarId and can display up to 28 entries.
GP2 then selects the fastest 26 drivers for the race. The race HUD follows those 26 actual participants, regardless of which of the 14 teams they represent.
The two drivers excluded from the race are selected by GP2’s qualifying results. GP2Lap does not change that selection.
16. Updating a season later
To make additional changes:
- Open EDITOR.html.
- Load your saved editor project or current CFG.
- When opening a CFG with external logos, also select its corresponding .F1L files.
- Make the required changes.
- Export a new ZIP.
- Extract it into the game folder.
- Restart GP2Lap.
Keeping the editor project is recommended because it stores the converted logo data and is easier to update than rebuilding everything from the CFG.
