Instrument cluster eprom

[M Richard Weiss]

I have a used replacement instrument cluster for my 2002 Boxster s, manual transmission. It will replace the original that has an error reading oil level. I’ve read the eprom, 93c86, from the replacement, but the code doesn’t look right. I would like to start with a valid binary file for the eprom that I can edit to match the Auto’s vin. Does anyone have a copy of the binary file they’re willing to share or know where I can download one?

I already sent Richard the file.  However for those who may need the same resource at some future date, I have attached the BIN file and a pdf that show what the code looks like.  To read the BIN file you will need to download a hex reader.

Hi.
I want to read out my 93c86 chip of my BoxsterS 986 facelift instrument cluster.

I have TL866A programmer.

Can sombody tell me if it is possible to read and write the chip with this programmer?

I've changed my instrument cluster to a version with the better graphic dot matrix display but want to correct the mileage.

Is it right the mileage is stored in lines 300&310 and 500&510 in a 2kb dump file?

My thougt is to copy these lines to the new cluster.

Any recommendation to use the programmer?
I found a pdf instruction. The author recommend to short the crystal on the PCB.

Am I right I dont need any power supply to the PCB? It is enough to connect the 93c86 with an IC clamp?
Thanks
