Forza Horizon 6 overlay setup and troubleshooting
Follow these checks in order. They separate a Data Out problem from a HUD that is hidden or off-screen.
Overlay not showing
Find the first failed check
Click the connection status to check whether Forza is detected, Data Out is arriving, and the overlay is enabled or hidden. The panel explains what to try next and links to Diagnostics.
- 01
Confirm that Wisp receives packets
Open Diagnostics while actively driving. Packet rate should be non-zero and packet age should stay low. If both remain idle, fix Data Out before changing the overlay.
- 02
Match the address and port
Use the loopback address shown in Wisp and the same port in FH6. Reserve that local port for Wisp.
- 03
Leave game menus
Wisp hides the driving HUD when driving is not active. Return to the road before checking the speedometer or attached gauges.
- 04
Recover the HUD position
Unlock the overlay, restore or move it onto the active display, then lock it again before driving.
- 05
Check display mode
Make sure the selected Wisp layout is enabled and the stock FH6 speedometer setting matches the instructions shown in Appearance.
Analogue tachometer
Check needle motion with G-SYNC or VRR
Update to the latest Wisp release, which includes the G-SYNC/VRR fixes. Keep the main HUD entirely inside one monitor. GPU rendering is the default.
Compare Wisp with the stock needle while Forza has focus, using your usual resolution, frame cap, display mode, and G-SYNC settings. Check again after several minutes. If the needle still looks uneven, a brief G-SYNC on/off comparison can help describe the problem; restore your original setting afterward.
CPU rendering remains available in Diagnostics for the Analogue tachometer. After changing it, right-click Wisp's tray icon, choose Exit Wisp, then reopen the app. Turn CPU rendering off and restart the same way to return to GPU rendering. CPU mode can increase CPU usage.
For a report, enable debug logging in Diagnostics, reproduce the problem, and export the debug ZIP. Include your Wisp version, rendering mode, resolution, refresh rate, G-SYNC setting, and which app had focus. Note roughly when the problem happened and how Wisp compared with the stock needle. Review the report before sharing it; it stays on your PC until you do.

Boost pressure and tire temperature
Both gauges use standard FH6 Data Out values. Set attachment, size, and units in Appearance > Gauges, and customize colors in Appearance > Colors. In the legacy interface, gauge controls are in Appearance and colors are in Extras.
Boost gauge
The boost-gauge toggle shows a stationary zero gauge on naturally aspirated cars. Electric vehicles never show it. Pressure readings begin after positive boost is detected for the car. Under Boost pressure, enable Show vacuum pressure to include negative pressure reported by FH6; the option is off by default.
Tire-temperature gauge
Front is the average of the two front tires. Rear is the average of the two rear tires. The display runs from 50°F to 350°F and holds both the marker and number at the upper end when FH6 reports a higher temperature. Fahrenheit and Celsius are available.
Drift angle
Set up the drift angle gauge
Open Appearance > Gauges (Appearance in the legacy interface) and enable the drift angle gauge. Select Drift Zone angle bonus for the verified scoring profile, or Custom target to choose your own angle and tolerance. Both modes support the Steam and Xbox app / Microsoft Store PC editions. If the scoring profile is unavailable, Wisp shows angle-only guidance without a bonus percentage.
The scoring-angle range starts at 10 degrees and its angle bonus saturates at 59.4 degrees. The percentage shows your share of the maximum angle bonus. Use it alongside the game's score, your speed, and your line.
Adjust size in Gauges and move the gauge with Edit HUD layout. Dark mode adds shading around the readings. Black background adds a separate fill with adjustable opacity. Below 5 mph ground speed (about 8 km/h), both modes hide the angle, marker, and bonus. Reset position returns the gauge to its default location.

Use Wisp on a second monitor
Move Wisp to the monitor you want to use, then choose Display mode from Dashboard. Use Fill screen for the whole monitor or Resizable for a borderless window you can size to fit. F11 switches modes from Dashboard. Escape exits Display mode.
Change application colors, borders, glow, surface opacity, spacing, text, and particles in Appearance. To return to the previous interface, enable Use legacy interface in Appearance > Layout and restart Wisp. Saved HUDs, calibration, profiles, and runs are retained.
Runs
Record a drive and compare the result
Once Data Out is connected, open Runs to record telemetry and compare saved attempts.
- 01
Choose how recording starts and stops
Choose Options to open Recording options and shortcuts. Set a countdown if you need time to return to Forza, choose a timed stop, or stop manually. Recordings can last up to 10 minutes. Optional shortcuts let you record and mark moments without leaving the game.
- 02
Save the run and read its summary
Start recording, drive your section, then stop. Give Wisp a moment to prepare the report. Choose General, Acceleration, or Drifting analysis, and read What stands out alongside the stats and data-quality notes. Edit the run details to name it and note the tune or conditions you used. Names, tune labels, and notes save automatically, including when you switch runs. The indicator changes from Saving… to Saved; if saving fails, choose Retry and check that it reaches Saved.
- 03
Open the graphs
Select Show graphs, then choose Overview, Engine, or Tires & handling. Customize shows, hides, reorders, and resizes graphs. Move over a time graph for shared readings, or drag across it to select a section. Range & cursor contains the exact controls. Choose Summary to return to the report, with statistics available as cards or a table. Save image exports the current graph view.
- 04
Compare a second attempt
Choose Compare, select a saved attempt as Run B, then choose Compare selected. A and B have different colors and line styles. Compare overlaid or side by side. Match an acceleration speed range only when both runs complete it; otherwise Wisp explains why matching is unavailable. Keep the route, assists, tires, and starting conditions consistent, and add your tune settings to the run notes.
Use Search runs or tunes in Runs to find a run by its name or tune label. Clear returns to the full list. Open the selected run's Export menu to choose a .wisprun file for importing and comparing later, or CSV for the recorded telemetry. Import runs accepts multiple .wisprun files or a Wisp library ZIP. Export all backs up the library. Delete all asks for confirmation and offers Undo; its recovery copies stay on your PC. Imports skip identical runs and reject conflicting duplicates without overwriting existing data. Files stay local until you share them. Debug ZIPs in Diagnostics are separate reports for troubleshooting Wisp.
