Hey everyone,

I just updated to R63 from R40 and I have a few questions about the R63 update compared to R59:

  1. Adaptive Cruise Control (ACC): On R59, the ACC speed increased by 1 km/h with each joystick press (instead of 5 km/h as before). However, on my Xpower R63, it still jumps by 5 km/h.
  2. ACC to TJA Toggle: In R59, a long press on the left wheel middle button (ACC on/off) toggled between ACC and TJA. This feature isn't working for me on R63 (it was working on R40).
  3. Charging Percentage: I can change the charging percentage directly within the infotainment system (without using the app). I read that if the update isn't performed well, you can only change it through the app...
Did MG roll back these R59 features in the R63 update?

How is your R63 update preform?
I'll also mention that the Bluetooth issue I had with my iPhone not connecting automatically has been resolved. I'm using the CarlinKit SE Pro CarPlay Dongle.

Thanks!
 
1. This isn't affected by R63, which is an Infotainment-only update. You need other software updates to get the ACC change

As to the others, I'll let a Trophy/XPower owner respond

Could you please provide the names of the other updates? I need to explain them to the dealer
 
SC077 is one update, which improves the LKA (Lane Keep Assist) performance and is available in the UK/EU. I can't say what is available in Israel.
 
I've got an XPower in R63.
ACC: the increase is by 1km/h
ACC to TJA toggle with a long press on left joystick.
ACC behaviour is due to camera module (FVCM) and front radar (FDR) updates.
 
Adaptive Cruise Control (ACC): On R59, the ACC speed increased by 1 km/h with each joystick press (instead of 5 km/h as before). However, on my Xpower R63, it still jumps by 5 km/h.
For each version of the ACC updates you have always had both the 5 and 1 unit change available, it is just how these activate that has been swapped. In some version of the ACC software the 5 unit increment is a single blip with the 1 unit increment being a long hold whilst in others it is the reverse of this.

There are a couple of threads which list various modules and the software versions they run, I think there was someone who posted from France who had a full list of all modules and software versions
 
Does anyone know how to get the R63 update? I have 2023 X Power that is on R40.

I went to the dealer service centre yesterday in Tamworth (Polesworth garage). I went in armed with a list of issues. The usual list including the terrible Lane Kill Assist.

When I picked the car up the dealer told me there were no faults. I explained that there are issues and I wanted the update for the LKA and the R63 update.

After a lot of discussions, me showing them the articles one Which magazine about the LKA they did check and my car was eleible for the LKA update, which they applied and seems to be much much better. My ACC now goes up in +1 tap and +5 long hold increments - by the way.

However, the infotainment system is still on R40 and despite me showing that there has been three subsequent updates he could not apply any of them.

So my questions are:

1. What is the latest version that can be applied to the X Power? - seems like R63 is available
2. How / where can I get this applied?

Thanks in advance

1. Need to know the whole software code to answer this one. Some X Powers have later versions where the R number does not correlate to previous.
 
Look at the VNCI thread in the MG4 board ... that gives info on how to do updates and where to get the files.

Note that R63 can be updated by USB pendrive but the car still needs to be connected to a computer running SIPS so that a configuration can be updated, otherwise the target charge slider (setting 80% etc.) doesn't work.
