Overview
MHD OBD2 Wifi Flasher was specially
developed and designed to operate the
Ethernet OBD2 diagnostic and coding
features via wired J2534 port and
wireless via an embedded module based
on the universal serial interface network
standard,built-in TCP / IP protocol stack,
enabling the user serial port, Ethernet,
wireless network (wifi) interface
