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

[JBanzhaf]

sorry for late response, yes you are right the main eeprom data has been lost with wrong reading. i am using dsp3+ programmer and the cluster for e36 m3. so i need your help to send me dump for both eeprom so i can flash it.

It looks like that’s a late model E36 non-M euro cluster. Unfortunately I don’t have any EEPROM dumps from any of those. I’m not sure if it’ll work, but I can get you an EEPROM dump from a US spec M3 cluster. Then maybe you can code it back to euro spec non-M using NCS Expert.

thank you for response, please if you can try to send me us spec m3 cluster epprom dumps. atleast my half job will be done.

Burhan, I just sent you an EEPROM dump from a US spec E36 M3 cluster. It should match the odometer mileage on your coding plug. So it should not have a tamper dot illuminated. Hopefully this works for you.

Thanks,
Joel

Thank you so much, i will write it and update you soon

i tried with the dump but it is showing code eep2. also the guage is not working at all. what to do now. appreciate your help.

The EEP-2 fault refers to an issue with the internal EEPROM. It can be either a hardware fault, or an issue with the binary on the chip. In your case, it’s most likely an issue with the binary. Read the dump from the EEPROM again, and verify that it perfectly matches the dump I sent you. Sometimes when you flash these EEPROMs, it doesn’t flash all of the sectors correctly. This will cause this issue. If it still doesn’t work after making 100% sure that it matches the dump I sent you, you’ll probably need a dump off of an identical cluster. In that case, the dump I sent is not compatible.

Hey, I was hoping you could send me the EPROM file for a z3 to z3m conversion, I've just recently swapped a S54 into my Z3 and need to get the gague cluster to have the right range response. I've already read and saved the EPROM file that was stored. If you can help with the coding plug too the mileage that was pulled from the car was 107305 but any help you can give would be great.
Thanks

Ijust sent you a DM with the EEPROM dumps you're asking for. If it's going in the original cluster from the car, and the mileage already matches the chassis, you won't need to flash the coding plug. Just in case that's not the case, I also sent you a coding plug dump with your mileage on it. Follow the instructions in the first post. After completed, you'll still have to "sync" to mileage from the coding plug to the internal EEPROM to clear the tamper dot.

You're the best, thank you so much!
