Try the controller interface
This is the actual OpenHaldex interface — the same one the controller serves over Wi-Fi, loaded straight from the firmware repository. Pick a drive mode and watch the engagement respond, or dig through every setting before you buy.
It’s a simulation. The interface is real, the controller behind it is not. Live values come from a looping drive cycle, and anything that would reach real hardware or the network — firmware updates, Wi-Fi setup, clutch learning and UDS diagnostics — will say it needs a real controller rather than pretend to work. Nothing you change here is saved.
Things worth trying
Switch drive modes
On the Dashboard, tap between Stock, FWD, 50:50, 60:40 and 75:25 and watch the engagement gauge and response trace chase the new target.
Open the Expert tab
The lock map sets engagement against road speed and throttle. Change a cell, switch to Expert on the dashboard, and the simulated coupling follows your own curve.
Read the Diagnostics tab
Clutch temperatures, terminal voltage, CAN bus health, free heap and frame counts — what you would actually use to diagnose a car.
Browse Settings
Haldex generation, standalone operation, dash-button mode forcing, brake and handbrake following, LED brightness and the rest.
How this works
- LIVE
Always the current firmware
The interface is fetched from the OpenHaldex-C6 repository each time the page loads, so it is whatever shipped in the latest release — never a screenshot or a stale copy.
- REAL
The same code as the car
No mock-up. The firmware’s own HTML, CSS and JavaScript run here unmodified; only the controller underneath is simulated.

On a real car
Fitted to a car, this same interface shows live CAN data from your vehicle and Haldex unit, and every change is saved to the controller.
