Thanks john! I think I may have used your very data to connect an arduino to the cluster!
I looked in a lot of different boards for that info.
My biggest question was - how is the data stored on the coding plug, and whether it keeps the number of cylinders in the car. So that if I could just take the coding plug from my car and align the miles to an m3 cluster, whether that would work ok with it,or not.
Thanks again!
