Im not too sure if anyone is interested in this, or has a VE Commodore to play with, but anyway here we go.
INTRODUCTION
The following information is considered a work in progress.
Because much of the useful information concerning memory locations used to store different cluster information is still not known.
Also to be able to support a number of instrument clusters, ultimately we will either need to know what every memory location does, or have a dump for every type of cluster, as well as vehicle options such as Auto, Manual, V6, V8, etc...
The VE range of instrument clusters use a 95160 EEPROM, which can be read from and written to using a suitable programmer, and a 3M SOP Clip (The EEPROM does not need to be removed from the board for programming).
The 95160 EEPROM Is labelled U7 on the instrument cluster board, and is located above and slightly to the right of the Main chip.
The following is a list of known memory locations, as of September 14, 2011.
