D-Sync D1 Dongle

Your car's secure communication bridge — Wi-Fi to your phone, certified protocols to your ECU. Wi-Fi / USB-C dual connectivity · Standard UDS over CAN. From $129 USD.

Communication

• Wi-Fi pairing — Direct connection to the D-Sync app. No cables to your phone, no Bluetooth pairing dance.
• OBD standard — Plugs into your car's OBD port. No adapters, no modifications.
• Mercedes platform — Tested across the supported AMG chassis lines. Known-good protocol implementations.
• No VIN locking — The D1 is never locked to one car — move the same dongle freely between multiple vehicles. Licenses live in your account, not the hardware.

One dongle, every feature

• Pair with the D-Sync app to flash ECU — D1 handles the OBD-side conversation. The app drives the user experience and holds the tune. Browse packages
• Read fault codes & live data — Same dongle, no extra license required. Built into the D-Sync app.
• Adjust Airmatic ride height — When paired with an Airmatic license, the D1 unlocks live mm-precision suspension control. See Airmatic
• ECU coding & everything that comes next — Coding is live — it just needs a D1 firmware update first: grab the updater from our Support page, or update straight from the Android app over USB OTG. Future D-Sync features ship the same way, no new hardware required. Get the firmware updater
