MG4 Software Update Thread

You can do this with every version

After updating all the modules using SIPS a few days ago, I noticed these things:

• the light sensor is no longer super sensitive (on auto it turned the low beam at the slightest cloud or when driving under a tree)
• LKA seems to be tamed even more(I already had SC077 applied in April 25)
• when I open the charging port, HV battery gets disconnected. I don't think it was like that before

People who have all modules updated, what other things did you notice ?

MY22 Luxury

After:

I confirm all improvement you said and more :

• No more issues with 4G (TBOX) (MPU updated too)
• DC charging is a little bit faster (10 to 80% in 23 min vs 26/27)
• Less troubles to start a DC charge
• TJA is more smooth with last electric steering update
• Better control of power at small speed with last IMCU update

Key mapper is nice to have.

T-box MCU should updated before the MPU?

 

[Mouss]

No first MPU.
There is a message when you try to update MCU when MPU isn't up to date.

Last MPU is SNAKP23E32 for MY22 and MY23

Another thing I noticed after modules update: the car power off after some time is not used. Not sure about all the conditions, but today was like this: doors closed, no one in the car, HVAC off. Maybe it detects that the key is not present or/and no one is in the car(seat sensors)

@EV Focus RO

In the image, it looks like you have the current SIPS version 1.0.2.5 ©2026. How does the "authentication code" from MG/SAIC work for using SIPS?

The old SIPS software works without authentication; you only have to pay for usage (1 hour, 1 day, etc.) and then you can use it.

I'm currently using SNAKP18E32 on my Lux 22"Trophy" r67.
Could I update via USB without SIPS?

 

[EV Focus RO]

@Pisuke No. Must use USB for MPU and SIPS for MCU

 

[TBR1972DK]

@TBR1972DK Interesting . I only know R36 for SWI133.

Same here. I really hope that this R41 fixes the issues with the camera and the trafficsign recognition.

Thanks, I hope to read more to clear up my doubts about all the technical terms/modules.
Is it possible to update everything via USB and then later buy a VDI3 without problems, or can I directly purchase a session with SIPS?
I'm about to click to purchase VNCI VDI3 Roewe MG Wuling Maxus.

I installed SIPS 19-11-14. Not sure why it says 1.0.2.5
