PUBLIC: Holden VY/VZ Instrument Cluster EEPROM Programming

[Rerouter]

Here is the dump off of a 2006 VZ Commodore, Single Screen, Manual Vehicle,

LVL1 Standard,

0x03C - 0x03D looks to be speed calibration in imp/km, while the speed displayed looked to be 6120 imp/km, I would not put it past Holden to scale the displayed speed down a little, rather than display the 6232 imp/km i read from the eeprom

for anyone bench testing there cluster, divide the imp/km by 60 and that will be the Hz to drive into the speed input to display 60KMph

If anyone is interested, attached is a dump from another VY cluster. I know just about everything else has already been mentioned - the Eeprom is an Atmel 24c04 I2C eeprom - Nice and easy to read / program. Not sure what car this is from, I just played around with a certain section of the dump, yet to have a car to test it properly in, but will eventually make its way into my VX SS with complete VY dash + trim.

Have fun

Has anyone worked out the factory shift light hex location? that's these dash people say have?

[gruntly69]

I'm pretty sure it was found ages ago, if I hunt through my files I should be able to find info about it.
What's the exact dump you want to use it on?

[Thathsvkid]

a vy clubsport series 2 if that helps my reader isn't working atm :/

[gruntly69]

[oldescratch]

Attached are some vy/vz eeprom locations. Airbags, transmittion, ect.

Hi Guyes,

Does anybody have any bin files to suit a VY Monaro clusters, I think it is a series 2 or 3.
