Anyone familiar with the technical details of the CAN (Controller Area Network) on the HM? I suspect it's similar on other Ducs. I'm looking for low level (bit level) details of the interface.

Thanks!

In case anybody wants to know what the CAN does here you go: (source is workshop manual)

Signals exchanged between instrument panel and engine control unit via CAN line are the following:
- vehicle speed (engine control input)
- neutral selected (engine control input)
- engine oil pressure (engine control input)
- lubricant temperature (engine control input)
- starter motor activated (starter button) (engine control input)
- first level diagnosis codes generated by the control unit
- engine rotation speed (engine control input)
- overrev reached (gear shift rpm signal)
- service needed (service warning light on the instrument panel on)
- temperature of taken-in air (instrument panel input)
- battery voltage - Bike model identification
- EOBD warning light
- Immobilizer recovery
- atmospheric pressure (sensor integrated into the instrument panel).

It would be cool to raise the rev limiter up to 9500. I think DukePilot did that with the RB but from dyno charts the power peaks at 7500. It would be awesome to have that additional range if it was still pulling.

Maybe DukePilot can chime in on his experience

Don't know the details about the CAN interface. All I know is that the RB3 unit plugs in between the sensors and the ECU and the TPS. On my bike peak HP is at 7500 and holds it pretty well till about 8250 where it starts to drop off more quickly.
