Introduction.<\/h2>\n\n\n\n

First post! first of all – welcome to my personal blog!<\/p>\n\n\n\n

The following code that I am sharing is to enable needle and led sweep for cluster VMMJ08MH<\/strong> running software version 9.00<\/strong>, this cluster comes with no factory software patches, so revision is FF FF<\/em><\/strong>.<\/p>\n\n\n\n

\n

This patch also reduces the factory smoothing applied to the needle, so they move faster – kinda like DSG clusters<\/em>.<\/p>\n<\/blockquote>\n\n\n\n

Patch data resides in EEPROM memory, starts at address 0x4F6 <\/strong>– the first 6 bytes are the patch header, and the rest (up to 0x7DF<\/strong>) contains a mix of code block (this is where our patch is<\/em>) and data block.<\/p>\n\n\n

Installation.<\/h2>\n\n\n\n
\n
ATTENTION<\/strong>: always make a backup prior to modification!<\/p>\n<\/blockquote>\n\n\n\n
You will need your cluster EEPROM dump, you can use kw1281test<\/strong> in order to do so – once you have your dump, open it in any hex editor and go to address 0x4F6, <\/strong>it should look like this:<\/p>\n\n\n

Once you have copied the patch data, paste it at address 0x4F6<\/strong>, save the file and you are ready to upload!<\/p>\n\n\n

Upload.<\/h2>\n\n\n\n
In order to upload the patch code, I highly recommend using kw1281test<\/strong>, patch can be uploaded over the K-Line using a OBDII ‘dumb’ KKL interface using this software – it will not be covered in this blog post, that is for another time.<\/p>\n\n\n\n
Disclaimer.<\/h2>\n\n\n\n
\n
ATTENTION<\/strong>: the code is ‘as-is<\/em>‘, it has been heavily tested<\/em> but use it at your own risk<\/strong>, I am not responsible for any damage and\/or malfunction to the cluster.<\/p>\n<\/blockquote>\n\n\n\n
If you enjoy the mod, please consider donating since this is very time consuming, reverse-engenieering the code is something hard to do.<\/p>\n\n\n\n
I also want to thank gmenounos<\/a> for the software kw1281test<\/strong>, without it this patch would have been very hard or near impossible to make.<\/p>\n\n\n\n
Happy modding \ud83d\ude42<\/p>\n\n\n\n
