I’m using windows laptop With vlink FS usb and I have installed sgw Bypass. Is there a chance that low battery health could impact this?
Low battery may be an issue, but I would look at the COM port settings in Windows first. Check this Library post Multiecuscan (MES) Setup and Connection Timeout Troubleshooting
Hi! Thank you for this useful collection.
I just found it, and I was wandering to change my battery settings. (A few months earlier, I changed the battery 80Ah/H7 Flooded → 95Ah/H8 AGM.) - 2.2 Diesel
My default proxy values:
byte 5: HEX 30 (0011 0000) / (I don’t understand why the last 4 digit is zero)
byte 63: HEX 01 (0000 0001) or (0001 this should be the last 4 digit) / 80Ah, 680A.
Am I understand correctly, I should be change these two values according to the list just convert the given binary values to HEX?
eg.:
byte 5: binary (xxxx 1011) → HEX 0B (zero+B or simply just “B”?)
byte 63: binary (xxxx 0010) → HEX 02 (zero+2 or simply just “2”?)
So the change in HEX:
byte 5: 30 → 0B
byte 63: 01 → 02
Or I have to keep the first 4 binary digit from my original value?
byte 5: binary (original first 4 digit: 0011 + new last 4 digit: 1011 = 0011 1011) → HEX 8B
byte 63: binary (original first 4 digit: 0000 + new last 4 digit: 0010 = 0000 0010) → HEX 02 (zero+2 or simply just “2”?)
Here is my proxy:
Then I need to do a proxy alignment?
For your help, thanks in advance!
Best regards: Süti
I am already setup according to this post
I would then consider charging the battery and keep it connected during this process.
I replaced battery for new one and it still didn’t work, I tested the program and obd interface on my moms 2012 fiat freemont and it’s perfectly working. It seams to be a problem with something in alfa. I have no clue what it is
There was misinformation in the post. I updated it with more accurate byte/bit information…
Body → CAN Setup
Battery type
byte 63, bits 0-3 (bit order is: 76543210)::
xxxx0001 - 80Ah 680A - default setting for Giulia/Stelvio EU
xxxx0010 - 95Ah 800A - default setting for Giulia/Stelvio US
xxxx0011 - 80Ah 680A - default setting for diesel Giulia/Stelvio
xxxx1000 - H7 flooded;
xxxx1001 - H7 AGM;
xxxx1010 - H8 flooded;
xxxx1011 - H8 AGM - default setting for Giulia/Stelvio MY20 models US/EU
You would take your existing byte 63 value “01” and convert to binary “00000001” and update bits 0-3, so your new binary value for byte 63 is “00001011”. Then convert that to hex for the value to enter in to byte 63: “0B”

Most Significant bit is on the left (#7) and Least Significant bit is on the right (#0)… fyi fwiw
FYI, there was a really good write-up that someone shared with me about the charging system for the Giulia/Stelvio. I have been trying to find it again, but failing. It has great information about the different charging methods it uses and what is required for it to enter certain charging modes. You may only need to reset your IBS and follow the requirements for the system to adapt properly. If I find it, I will share.
What adapter i need to use in order to change that setting.
As stated, I use the vGate vLinker MS bluetooth and have good success with that. No cables needed. When it tells you to use a certain cable color, just click ok/next/continue.

Hello Fizz can you please update the google docs link it appears to be dead
Thank you
Thanks,
I moved to OneDrive and wait for people to mention broken links. lol
updated the link to the new location
Regarding battery coding.
As far as I know pre2020 cars only have EFB charging curves implemented. So their BCM cannot use anything other than the basic indicator for battery capacity. Byte 63 is x1 for up to 80ah and x2 for 95ah or larger (i.e. the first two options in the list in the popular settings doc).
Not sure why diesel needs different coding for same battery?
Later cars do allow the AGM settings.
Here is the charging system guide mentioned. It does not include byte coding as at last edit the reason for failed codings was not clear. I may reinstate a coding section in next update.
Hey @Barbuck this is JeFizz from the Giulia Forums. I need to spend a bit more time making sure that I link that doc in a few places on here. I’ve been doing my best to make people aware of your findings which could help them out when they think their 2 year old battery is dead, when the problem, more than likely, is that it needs to get into the proper charging routine.
Cheers!
Here is another guide I pulled together regarding battery selection and coding. Feedback welcome.
