Flashing ECU via Bluetooth

Hi guys

I see that Versatuner offers an option for flashing a tune via bluetooth using either the OBDLink LX/MX bluetooth dongle. I have two questions regarding this:

1) Has anyone flashed a tune via bluetooth and how was your experience? Would you reccomend this method or is it safer to stick to the OBDLink SX cable?

2) OBDLink discontinued the OBDLink MX and replaced it with the OBDLink MX+, which is superior in a number aspects and seems like a worthwhile upgrade over both the LX and MX. Can Versatuner also flash a tune via OBDLink MX+ or is it strictly limited to OBDLink LX/MX?

 

I would not mess around with flashing wirelessly, that's a good way to brick your ECU even if it is possible
