Frequently Asked Questions
Yes, simply tap the MHD Store button. The ECU connection is checked before displaying available purchases.
MEVD1726 eqipped BMWs need a one time bench flash in order to jail brake the ECU to allow flashing via the OBD port. This process requires uninstalling the DME from the car and sending it in to a MHD partner for the jail break / unlock.
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.
Yes, you can purchase multiple licenses with one google play account.
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:
– let the battery charge fully first and leave the charger on
– alternatively, bridge the car to another running engine
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
This happens when the internet connection is lost just after the purchase. Either wait 24 hours for the Google purchase cache to be regenerated, or go to android settings, apps, MHD, clear data cache, reboot the device.
After that, check the internet connection is active, and start MHD, wait 5s, and check licenses with the top right menu, show licenses (no connection to the car needed).
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.
Then upload the .csv file in MHD / datalog to datazap.me
