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

[Steezyz3]

You're the best, thank you so much!

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.

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.

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,

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

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.

[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.

Sorry I'm only replying to you now. I didn't see the post until now. I just sent you a PM asking you some additional details. I should be able to help you get it fixed. I just need to know exactly what you have, and what you're trying to do. The one dump you attached looks like a good dump of the coding plug M93S46 EEPROM, with a good and non-corrupt mileage. I'm not sure what the other dump is, as it does not match the format of the CAN bus Z3 cluster's ST93CS56 dumps, and the non-CAN bus E36 clusters don't use ST93CS56 EEPROMs. It would also be helpful if you attached photos of the chips and the IC that you're trying to flash, to help identify what you're working with. I think you may be possibly trying to flash your internal EEPROM with the wrong settings.

Hey Joel. I needed some help with a few things are you able to pm me? I guess my accounts too new to message you first
thanks

can anyone send me dump for coding unit and main eeprom fo bmw e36. my both dump is got corrupted and now getting error in display. please help

hey mate,
I am trying to change the mileage for the cluster , as my older cluster is damage and i got another cluster, now i would like to write the orig km, which i am unable to do so, rear 93c46 code plug and main eeprom (unknown chip), seems the main eeprom is corrupted now as now the cluster diplayed eep-2, before when i was trying to rear and write code plug eeprom the km was showing same.
i have attached both the file for cluster, can you help me to reflash and send me , or if you have new file to be reflashed please help me to send.

i would like to know while writing the main eeprom the error pops up in programmer (DSP3+) code error while writing which means chip is not rewriting the data, even now i am trying to rewrite orig dump also it is same. so cna you tell me which eeprom it is so i can use new eeprom and reflash with new dump.

thank you

Hello

I am doing an S54 swap into an 01/99 Z3 that originally came with an M52TU/MS42, but that I had previously put an M54/MS43 into. Now I finally own an S54/MSS54 and am collecting all of the little things to make it work well. I have a CAN 02 cluster that works well with the MS43 DME (but I see that you have had better luck with CAN 03 clusters so I can pick one up if necessary). I would really appreciate if you could send me the EEPROM dump from the S54 Z cluster so I could reflash mine. The chassis and engine both have around 150K miles on them, so if it's possible to just use my CAN 02 cluster I wouldn't have to touch the milage.

Thanks,
Nathan

Just sent you a DM with the EEPROM dump. Let me know if you have any questions or issues. This dumps works fine on all CAN clusters, so it will work fine on your CAN 02.
