Overview

The MHD Universal WIFI Adapter is a wireless diagnostic and tuning interface for select BMW and Toyota Supra MKV vehicles. This device plugs directly into the vehicle's OBDII port to enable mobile app-based flashing, logging, and code diagnostics without requiring physical cables.

Show original supplier description

By plugging into the OBDII port and establishing a local WIFI access point, the adapter provides a fast, stable connection between your mobile device and the vehicle's ECU. Technically, the unit features a modern, in-house designed chipset that supports multiple communication protocols, including ENET for F/G-series, CAN for E-series, and K-Line for older E-series models. The adapter automatically detects the necessary protocol for your specific vehicle and manages firmware updates on-the-fly through the MHD mobile application. It includes built-in power management to enter a sleep mode when the engine is off, preventing battery discharge. The hardware is compatible with various automotive applications, such as MHD, BimmerCode, BimmerLink, xHP, xDelete, and Protool. It is specifically optimized to provide improved flash speeds and connection stability over previous generations of MHD adapters, with unique functionality such as xHP special mode for G-series and Supra ZF 8HP transmission flashing. Please note that the purchase of this adapter does not include tuning or diagnostic software licenses.
