Product overview
One wireless dongle. Every MHD-supported BMW and the Supra MK5. No cable, no laptop, no faff.
The MHD Universal WiFi adapter is the last flash tool you'll need to buy. Plug it into the OBDII port, connect your phone to its WiFi network, and you're flashing maps, datalogging and reading codes in seconds — nothing trailing across the footwell.
It's the all-in-one replacement for the older colour-coded MHD dongles (black, orange, blue, pink). One body, three protocols inside it: ENET for F and G series BMW and the Supra, CAN for E series, and K-Line for pre-2007 cars. Plug in and it auto-detects your chassis and picks the fastest connection — you choose nothing, it just works.
Built in-house by MHD's engineers on a modern chipset, it's the quickest adapter they make: around 5% faster than the old black ENET dongle on F/G cars and roughly 30% faster on E-series KDCAN. DME unlock and first install in minutes; a map or options change in seconds.
It isn't locked to MHD, either. The Universal works with the apps you actually run — Bootmod3, BimmerCode, BimmerLink, xHP, xDelete, MG-Flasher and ProTool — so one dongle covers tuning, transmission flashing and full coding. G-chassis and Supra owners get the clean xHP unlock and the fast ZF 8HP transmission flashing this adapter is built for.
Leave it plugged in: sleep mode drops the power draw when the car's off, so it can live in the port for weeks without flattening your battery. Firmware updates over the air through the app, so new platform support lands without buying new hardware.
