OK I am an Electrical & Instrumentation Technician, have worked with very sophisticated PLC's, DCS, DIGITAL DRIVES & all associated field control devices.
The onboard Computer is just a smaller version of an Industrial control system, where software parameters can be set, changed and manipulated then the mathematics are crunched within the computer software. The wheel and final drive sensor is merely a counter, sending pulses to the computer.
If it is possible to access the Software Parameters shown in attached pics ( IF
![Huh ???](http://forum.hexcode.co.za/forum/Smileys/default/huh.gif)
? ) , then it is possible to change the complete dynamics of the ABS and Instrument cluster on the bike. Million dollar question ....... can these Parameters be accessed using Diagnostic Device ?
My Speedo is very accurate in KM ........ the ODO is reading about 60% of the actual distance travelled (ie Miles)
How do you change the ODO from Miles - KM ? Which Parameter needs to be accessed ?
Obviously the BMW Techs have DIAGNOSTIC TOOLS far more sophisticated than a GS911.
