To be honest, doing a customised onboard computer whether it be android or linux based isn't that hard.
The hard part is know what protocol Kawasaki use in their CANBUS and writing the protocol code.
So:
1. on the handlebar there would be some sort of joystick control to navigate the menus
2. the onboard computer would allow:
a. customised display (so if you wanted to have TPS with battery voltage and temperature you could do)
b. be in colour
c. have bluetooth functionality
d. ability to install applications e.g. music player
e. integrated sat nav
3. and a ton of other goodies i've not thought of.
4. Use a beagleboard or some other small form factor board
5. Must have low power consumption
6. USB to copy music/data to the internal SD card
Obviously would need to display Kawasaki system errors etc.
Its not rocket science. The hard part is the CANBUS protocol. From my research the ZX14 chaps are trying to decipher the codes as well, and they should be the same as the Concours. If anyone here has the KDS database, that would help
. The manufacturers of speedohealer are developing their own low cost diagnostic kit for Kawasaki (sniffs messages on the CANBUS and decodes them). Once I have access to this kind of toolset it will make life easier.
If I do get it done, I'm just dreading the size of the writeup for people to do the customisation themselves. If people are interested in this I don't mind giving the project a bit more focus. At the moment its more for me to polish up on my technical skills.
