ECU Module version spreadsheet

[JodyS21]

I'll update this top post as more data is provided.

In an attempt to figure out what the different versions of all the software do/cause, we are putting together a list of peoples car ecu versions.
If you have the OBD2 device (currently being looked at in another post) or OVMS, please post your details so that I can update the spreadsheet.
If you could provide as much information as you can think of to explain what version you think you have please, to hopefully enable us to work out what the differences are.

Please add any ideas etc that you have.

Data regarding SoC & Voltages at full charge:
(SoC% seems to be related to the Max Cell Voltage)

I've created this graphic to show how the battery usage seems to really be:

Brilliant idea, It would be really handy if someone could upload the bad BMS version number from end of October. Also the new one from Jan

Soon as I get my dongle, we'll have the data from a new car with latest update....

@Septian
Does your car have the graphics on the dash when you change mode/kers?
I'm hoping the answer is Yes, as that potentially tells us its the SCU eco version that does this....

When I press the KERS switch the little 3 changes to a 2 or whatever, just the bottom bit changes

My kers and mode buttons only change the little symbols on the dash too

Damn it!!!!!!
FYI the graphics are on here:

Graphics on dashboard

part of the black exclusive with the larger battery pack... I’ll tell the wife who worries about the range this, I liked the black but she did insist on white or red!

www.mgevs.com

That's blown by potential SCU ecu version being the cause of it!

The only other difference then I can see between the 3 cars data we have, is not a version, but rather that the car with the graphics was one that has had the comfort pack 2 update (re)installed at the dealer and probably not from the factory.....

Oh wow, Mine certainly does nothing like that, I wish it did, that's pretty nice looking, haha.

I got mine October 2020 and i assume it came from the factory with comfort 2 already installed.

@Alan5

Rather surprisingly, you have a new HVAC version that haven't seen before, bit strange as it is very similar to the others (REL_DC_BEV_C036) except yours is A instead of C (REL_DC_BEV_A036).

You have a "new" BMS version too (1125600R15)!
I was guessing as you had the car updated in Sep 2020 they'd have put the latest BMS on it then and therefore you'd have the 7/20 version, but I'm pretty sure you don't as @AbuG & @shikoku14 have the 7/20 version which is a different number. Could yours be the very original (pre 12/2019) never been updated BMS?

Can you do timed charges and or AC charge unlocked??

You also share a couple of other new versions with @Kithmo:
EVCC (AC charging ecu?)
DCDC (DC charging or is it 12V battery topup charging ecu?)
TC (Traction Control?)

Any idea what that could be about?

I think your right about the BMS being the original pre 12/2019 as it will only charge AC with doors locked not tried timed charging yet but I am guessing it won't work . When it goes in for the next service I am reluctant to have any new BMS update as I am quite happy with the BMS as it is , unless it affects the warranty if I don't have it updated . Your other questions I will have a look at as I have only looked at what the app can do today but it all looks very promising ?

 

[JodyS21]

It looks like (need some more data to validate).

Original BMS is version - 1125600R15
12/2019 BMS is version - 0106600R17
7/2020 BMS is version - 0603610R28
Guess 24/10/2020 BMS is version - 1016620R40
Need the 15/1/2021 BMS version.

Not too sure on this:
Original? - EVCC 1770099611 / DCDC F01R0A7242.
7/2020 To allow AC charge unlock & Allow more timed/smart chargers -
EVCC 1770124111 / DCDC F01R0A7355.

EVCC (AC charging ecu?)
DCDC (DC charging or is it 12V battery topup charging ecu?)
TC (Traction Control?)

EVCC - Electrical Vehicle Charge Controller, this was updated to allow for upto a 10 hour delay to charging starting, more information here:

.

.

www.mgevs.com

OBC - On Board Charger, this was updated to allow for unlocked AC charging, but this module doesn't appear to report in the list above. Link above provides more detail on this too.

DCDC - DC to DC Convertor, I believe converts the HVB voltage down to a smaller voltage for charging 12v battery (and probably a lot of other functions too)
TC - Traction Motor Control Module
Both of these were updated as part of the SA017(HVB Fuse update), see image below.

Fantastic info, thanks

Got 12 car version dumps now

Got 17 car version dumps now.

I think with some certainty we can say these are the (UK) BMS Versions:
Original BMS is version - 1125600R15
12/2019 BMS is version - 0106600R17
7/2020 BMS is version - 0603610R28
Guessing 24/10/2020 BMS is version - 1016620R40 - Need someone with this to check it.
15/1/2021 BMS is version - 1230621A01
mid 2/2021 BMS is version 0210622EU1 !!!!!!!!!!!WTF!!!!!!!!!

EVCC We have 2 versions (Electrical Vehicle Charge Controller):
1770099611 - Think Previous version
1770124111 - Think is latest, Improves compatibility with smart and timed charging systems

DCDC (was updated as part of 6/8/20 SA017 to fix the main fuse blowing issue)
- seems (with 1 exception) to be linked to the EVCC version:
F01R0A7325 - Think is a very old version
F01R0A7242 - Is normally found with EVCC 1770099611
F01R0A7355 - (Normally goes with EVCC 1770124111)

TC (Traction Control - was updated as part of 6/8/20 SA017 to fix the main fuse blowing issue)
F01R0A7324 - Original version?
F01R0A7240 - ?
F01R0A7366 - Latest?
F01R0A7354 - Latest?

SCU versions:
194136858 C0807 - Older?
194136858 C0812 - Latest?
194136858 C0813 - Latest?

 

[Cocijo]

Great work. 0210622EU1 is the version with the remote app +100miles range auto aircon and faster infotainment ???

No because that’s what’s on mine and I don’t have either...

 

[Cocijo]

Has anyone successfully used an obd dongle using iOS and logged the data? I’d like to do mine.

I'm wondering if those BMS numbers are build dates, if you take the American date format into effect. (Not sure about the year, but the dates kind of stack up)
EG
1230621A01 (30th December)
0210622EU1 (10th Feb)
0603610R28 (3rd June)
Etc.
