Engine/trans/ecu wiring schematic?
 

I am looking for information. I need to find a detailed entire wiring schematic for a 2005 BMW X5 4.8IS.

Also, what model ECU does it have and what does it use for a crank signal, 24 tooth, a 48 tooth, a 58 tooth reluctor ring??

Thanks for any input...

What companies sell software to self tune this truck??

I am just starting research here and any guidance to what I am asking for is much appreciated.
