I have been in discussion with a fellow hacker via email and wanted to post some of the findings here to see if anyone else has had any experience (or luck) with using diagnostic tools on the OBD connector to interface with the car.
(If any interface gets full support for the ZS EV then it may mean that a Leaf Spy Pro type app will be possible with a cheap dongle)
List of interfaces tried by users (no functionality guaranteed, these are just reports from other users like you):
High level of control and data polling for the ZS EV. Has eZS and other foreign market vehicles that are similar to the ZS EV UK Model.
Can poll data for most ECUs present on UK vehicle. Has decode built in and can be easily reverse engineered. Has shown us a few of the key bits of data through the OBD port.
Most mature software for MG EV currently. Using “SAIC MG” module version 12.80 or later.
Available to purchase on eBay and other sites. The bluetooth dongle version comes with 1 manufacturer included for free.
Cost is circa £82
User: @mikeRES , Hardware: THINKDIAG (sold by uk-thinkdiag ) , Software Version: 12.80 or later
Autel MP808 (and other devices from Autel Line)
Interfaces via OBD and can talk to some areas of the car, company appears to be actively developing/reverse engineering from manufacturer tools. Has many features for ICE MGs and older EVs like the LEAF, but mainly focused on garage functions (brake bleeding etc.)
Use does seem to flag up some warnings on the dashboard when talking to the ABS module
Hardware: MaxiPro MP808 (note: there is a Bluetooth dongle which might be a cheaper option)
Software Version: Latest as of 22 July 2020
MG Official Diagnostic Tool - This is the dealer diagnostic tool, if anyone can share details of what the tool(s) is/are I would be very interested.
