The MHD wireless adapter allows you to reliably use all MHD features on the go, faster and easier than ever before. Just plug it in to the OBDII port, pair your mobile device to the Wifi access point created by the adapter, and you can flash, log, read codes etc. instantly – no cable needed anymore.
While using the MHD wireless adapters your phone LTE/4G data connectivity and bluetooth all remain active – and charging the phone is possible.
Adapters are compatible, or will soon be compatible with your favorite other apps – xHP, xDelete, Thor, Protools, Bimmercode and many more.
Two models are available:
Where can I get it?
Q:Do I still have a connection to the internet when connected to the adapter?
A: Yes, as long as you have cellular internet available (some devices require special settings to have cellular connection if WIFI has no internet)
Q: Why Wifi not Bluetooth?
A: Bluetooth is slower, and for future iOS compatibility only the slower BLE could have been used. WIFI is available for every device, has greater connection distance, a more reliable connection, is faster, and leaves Bluetooth available.
Q: Can I use it only at home?
A: The access point is created by the Adapter not your WIFI at home. This means you can use the adapter wherever you want.
Q: Can I use the RJ45 port on the black adapter for ENET tools?
A: Yes, the RJ45 port provides support for all ENET applications.
Q: Can I leave the adapter connected?
A: Yes, but we recommend to unplug if the car is not used for longer than 7 days to prevent extra stress on the battery. Attention: On G Series cars with factory alarm system the adapter must be unplugged because the alarm will be activated after locking the car.
Yes, simply tap the MHD Store button. The ECU connection is checked before displaying available purchases.
No. Once a flash is performed you can unplug your device.
No, you can ref lash as many times as needed.
Each vehicle has its own unique license (VIN and google account locked), tuning a different car requires purchasing a new license.
Q: Can I tune multiple cars with one MHD account?
A: Yes, but for each car a new license is required.
Licenses are personal and stored by google along the account used at purchase time. The purchases are tied by google to the first account and can not be transferred to a new google account.
It is highly recommended for long flashes (install, uninstall). A healthy battery will handle short flashes (map changes) fine but the use of a battery charger remains recommended.
The most common issues for failing flashes are lack of current or unreliable KDcan cables.
For the current supply:
Make sure ignition is fully on (insert key, press the start button without touching the brakes until the dashboard displays the actual fuel level).
If that stills fails, it’s often due to a bad KDcan cable. See page 5 of the user manual for recommended cables per country.
Press the monitor (auto log) button, stabilize around 2500 rpm / 3rd gear with DSC fully off. Mash the pedal, shift at 6500 rpm and 2-3s after the shift into 4th gear release the throttle and slow down, then stop the monitor.
