I compared those addresses to the known addresses of an mbox.... they were close but not the same layout. I moved your start point back 1 adress to start at 00 and added one address to the end like an mbox xdf has it.
your cbox data: 00 80 81 00 82 00 83 00 83 C0
mbox data:       00 73 00 73 00 73 00 73 00 73

You are looking for 5 values seperated by 0's
I hope this helps.

This image has different vmax data compared to newer images.
You found already the right words:
0x013272 is VABSCH
0x013274 is VHYST
0x013276 is VMAXO
0x013278 is VVORH

For all the conversion factor to km/h is 0.00781.

thank you !!! thank you !!!!

I was almost sure I have the right adresses !!! in the newer s4 files the vmax is a little bit different !!

you are completly right !!! the factor is 0,00781 or to get it easy take the value / 128 and you will get almost the same result
