DIY: Z3 Non-M gauge cluster to Z3M S54 Conversion

[JBanzhaf]

JMH083,

Welcome! If I understand what you’re saying, that should work. You need to read the dump from both the internal EEPROM and the coding plug EEPROM from your original cluster. Then write both of those onto your new one. As long as you have successful reads and writes, you’ll have a clone of your original cluster, with mileage and vin transferred.

Thanks,
Joel

Hi Joel

Thanks for your prompt reply, really appreciate.

So I will try, there are two option to copy dump from coding plug and internal eeprom : remove eeprom by hot air gun or to use special plug to get contact with pin

I have a 2001 50k KM cluster I can share the bin dumps from, as well as a brand new uncoded cluster that is virgin to share bin files from. The uncoded cluster isnt of much use though.
is there not a way to code the nonM canbus cluster via winkfp to flash z3m firmware into it?

[JBanzhaf]

Unfortunately, as far as I’m aware, Z3 clusters don’t use a flashable firmware. These clusters are coded instead. So WINKFP doesn’t have any functionality for them. I have tried coding it with NCS expert, but so far I haven’t found a way to make the necessary changes with NCS expert. If you feel like sending it to me, I’d be interested in seeing the dump from the uncoded cluster.

Thanks,
Joel
