Chevrolet Onix 2021 R7F701403

[caastellanos]

Hellooo everyone!

Sorry for being out of the scope for a while, but we have been working to find solutions for other cars...

I'd really like to have your help with this Chevolet Onix, it has a R7F701403 MCU inside the cluster, I was able to read it so you will find the files in the zip file here below.

The car has 157647 KM and I'd like to have something around 50,000 Km.

car looks pretty similar to Chevrolet prisma.

Thanks to all!

Hello!!

I'm trying it on my desk (it means that it's not on the car) and I got the same mileage (157646 km),

I have tried with files from other cars and it works fine on my desk, but when I install it in the car I got dashes (------) only, my thinking is that the file from other cars is different (automatic, or different in some way).

Tomorrow I'll have the car to drive it a few km and read it again (at least 2 or 3 times).

Thanks!

If I verified I always have differences between the written file and what's really in the file... looks like it's a part of the file that can't be over written D:

He will not share it mate, I collaborated with him yesterday to make the right dump for him in pm, I had the dump ready for him but seeing he didn't send the pinout after I asked him twice and because he didn't reply to you here on thread, I decided to not give him the right dump for his attitude. His answer was:'' I worked 5h to find the pinout, was not easy and every body wants it'', so he didn't share it with you or DK members but he expects to get helped by DK members. I mentioned that the pinout is not for me and is for DK member and I have the mcu pinout already on vvdiprog and I also sent it to him after posting here for you.
Not long time ago one of our DK mates asked me why I add password on my dumps from time to time, what's the mystery on the dump? There is no mystery just peoples' attitude!

Conclusion: Spending time to find the pinout for himself is more important than us spending from our good time to help him for free.

5 hours to find the pins haha ​​the next one that arrives I will do it and share it, I only asked for it for a matter of comfort
