I have a ELM-M1G connected to a computer via a serial interface. The time keeps rolling out of sync. It is running fast gaining about 1 min per month I did not purchase an ethernet adapter for my ELK. Does anyone have a serial terminal script or a small utility that will check the time on a Windows XP computer (Internet time sync is enabled on the PC) and then reset the time on the ELK-M1G? It looks like it can be done as there is an ASCII protocol spec.
