About

Haldex.Flash

Read full description

Haldex.Flash turns your iPhone or iPad into a flashing, tuning and diagnostic tool for Haldex all-wheel-drive couplings and VAQ front differentials. No laptop, no cable, no trip to a workshop. Plug the Haldex.Flash adapter into your car's OBD port and pair it. The app reads your VIN, box code and controller software version automatically, then shows exactly what your licence allows. LIVE TUNING Change how the clutch engages without reflashing anything. The PWM duty map is laid out by road speed against throttle position - adjust any cell, apply it to the controller in seconds, and feel the difference on the next drive. Start from a preset and fine-tune from there: • OEM+ - a subtle gain over stock. Less understeer and more wet-weather confidence. A set-and-forget daily. • Street - noticeable all-wheel-drive feel, planted through corners. • Sport - aggressive corner-exit traction and strong mid-range. • Track - maximum safe engagement for consistent traction under power. • Drag -maximum coupling for straight-line launches. FLASHING Install a performance calibration, go back to the original factory calibration, or load a custom file. The whole procedure runs over Bluetooth with live progress on screen. Safety checks run before anything is written, you confirm with a deliberate press-and-hold, and an interrupted flash can be recovered. DIAGNOSTICS Read and clear fault codes from the Haldex or VAQ controller, with plain-English descriptions instead of raw hex. Stored and pending codes are shown separately. LOGGING Watch live data as you drive - pump duty, pump current, clutch and module temperature, wheel speeds, supply voltage and more. Export the whole run as a CSV file to analyse later or send to your tuner. SERVICE Run a clutch pump relearn and read back pump calibration values. BUILT FOR THE CAR PARK, NOT THE BENCH Everything happens over Bluetooth from the driver's seat. Progress is clear at every step, errors explain what to do next, and the app keeps working if you switch away mid-flash. WHAT YOU NEED • A Haldex.Flash Bluetooth adapter • A Haldex.Flash account • A licence for the vehicle you are working on A NOTE ON SAFETY Flashing modifies the control unit that manages your vehicle's drivetrain. Changes may affect how the car behaves, and may affect your warranty. Only use settings appropriate for the conditions you are driving in, and make sure modifications are permitted where you drive.
