MG ZS EV ECU data via the Torque Pro app

[MG ZS EV WEST YORKSHIRE]

A nice to have....MG ZS EV ECU data via the Torque Pro app

 

[AbuG]

We know it's possible from the Thai group... As explained in the first post on Project OBD2 thread and the YouTube video there. What we need are the PID setup files. Do you have them ?

Edit
Imperial units MPH suggest likely UK setup

Did you add all the PIDs?

 

[JodyS21]

The OVMS guys have identified a lot of the PIDs:


I tried a few days ago to access the data (PIDs) using a serial terminal on my mac, connected to the bluetooth obd2 dongle.
I got connected to it, got some data back using the "default" codes, but when I tried to do any other commands using what I thought were the PIDs I just got no data.
I've got annoyed with it as I can't figure it out and have given up for now!

FYI
This is what I made a note of so I remembered what I was doing, if it means anything to you:
All commands start with [AT] space is optional.
AT commands are run by the ELM327. Others are just passed on.
AT Z reset all
AT L1 Enable line feed (0 off)
AT E1 Echo on (0 off)
AT H1 Headers on (0 off)
AT DP Describe the current connection protocol + N gives the number.
AT SP0 Protocol selection Automatic
AT SP6 Protocol selection ISO 15765-4 CAN (11 bit ID, 500kbaud)
01 XX Mode (hex)01 Show current data, XX = hex value of the PID.
02 XX Mode (hex)02 Show freeze frame data (Saved state data)
01-0A are OBD2 defined, 10(hex) onwards are manufacturer specific)
01 0D Request current speed (Value is km/h)
01 11 Request current throttle position (100/255 * Value)
Response 41 00 FF FF FF FF
0100 Request all PIDs available (1 line per ECU)
If more than 1 line/ecu is returned, turn headers on (ATH1) to see which ECU they are.
E.g. BB1E3211 = 10111011000111100011001000010001 = 01,03,04,05,07,08,0C,0D,0E,0F,13,14,17,1C,20
The last bit is an indicator if there are more PIDS, if it is 1 then request the next 32 bits using 0120 etc

Great post Jody, love a bit of HEX, just like being at work!

Finally found out what IPK stands for too, Instrument Panel.

 

[Stuart Wright]

We're planning on talking about OVMS and the app in the podcast on 29th March.
I'm looking for folks with some knowledge on the subject to join us.
Would any of you be able to make it? Using Zoom from 7:15.

If no one else steps forward, then here's your man, (follow the link) has experience of both podcast and OBD2/Thai app.

I couldn't possibly appear on a podcast until I've had a haircut after lockdown!

Easily dealt with MG style...

I've started creating a PID list for Torque at peternixon/MG-EV-OBD-PID

Some of the data is not right for me see screen shots. I couldn't download your file directly despite logging into GitHub. Had to copy the raw csv data into a plain text file naming it with .csv extension.

There is a conflict between the data my SoH is somewhat worrying and some of the other parameters are slightly out too compared to the Thai App. I was stationary but speed and rpm reading are greater than that.
Also I had just stopped the granny charge for a minute or so but it was reading as a negative current... although the BMS status charged from "charging" to "running" ( in ready mode). I took the Thai screen shot first and torque about 30seconds later.

Hi @AbuG
Thank you for your quick feedback!
GitHub is a software development system with a few fancy features to allow multiple people to sync changes with each other. Accessing the file via the "Raw" link is certainly one way to get it, or you could download the whole collection by selecting "Download Zip" from the "Code" button in the top right corner. On the other hand if you'd like to contribute changes, using a Git client like "TortoiseGit" or "Sourcetree" is the more advanced method.

Regarding my PID list, I only figured out how to get responses via Torque Pro yesterday evening over a glass of wine, but didn't have time to test that I had all the correct formula to process the responses in a valid manner. The SoH however is "valid" according to the OVMS spreadsheet that I used as a source, however I agree that it shows a different value when compared with my dash. I suspect that what the PID returns in the "correct" value before it's padded with a buffer by the dash, but I could be wrong and I will investigate this further.

The formula for the Speed and RPM on the other hand were not quite right and I have fixed those. Please grab the latest list from GitHub and let me know how you go.

Great job with this. Any chance of posting the usable file here please?

The whole collection (including readme, tested pids and pids under test) is at the project link above however if you are having trouble using GitHub then a raw link to the PIDs which seem to work correctly for me is https://raw.githubusercontent.com/peternixon/MG-EV-OBD-PID/main/extendedpids/MG ZS EV.csv

Hi, I downloaded that file from github and added it to my extended pid files on torque pro. Does this look correct to you? I have only 1 file! I wont be at the car to test this until this evening.

 

[nix]

Legend, thanks

@CDR I've just uploaded a significant update to the file which now includes most of the temperature sensors as well as tire pressure sensors. Make sure you grab the latest version

Hi @CDR
With the latest list (uploaded 25min ago) you should see 27 extra sensors while you are only seeing one. I suggest that you download the ZIP file (https://github.com/peternixon/MG-EV-OBD-PID/archive/refs/heads/main.zip) and grab the CSV from there as I think you may have corrupted the formatting when doing a copy and paste.

It should look like the following (although you'll need to create the dashboard yourself as I haven't uploaded it yet):

Brilliant thanks. I cant see anywhere to download the zip file. Ive been looking and looking. I tried opening it in chrome, explorer and edge and its not there. I know I must be doing something wrong. Sorry about this

Is it both of these files?
