Read/record battery voltage

Hi there,

Does anyone have advice on how to read/record the battery/system voltage on a 2009-2012 Daytona 675?

I have tried enabling the "ECU voltage" channel using the default OBD-II settings (automatic default protocol, no changes to initialisation comands of default OBD-II header) but with no luck. The only data RaceChrono seems to be able to poll/record are engine rpm, speed, throttle position, coolant temperature, intake temperature, manifold pressure, and vehicle standards.

Despite not being able to see the battery voltage in RaceChrono, I know the data is there, as TuneECU is able to read the battery voltage using the same bluetooth OBD-II dongle.

Being able to record the battery voltage is important to me as I am having an intermittent charging issue and I want to be able to be able to better identify when it is occurring while out on track (hopefully no more cooked batteries or ECUs...)

Thanks!

    I've tested the standard "ECU voltage" OBD-II PID on my car and it still works just fine. I think that your bike just does not support it. But I guess it's worth checking you're running the latest RaceChrono (v6.4.1/v6.4.2) as it has some OBD-II fixes.

    TuneECU app goes much beyond standard OBD-II functionality, as it does all sorts of things like remapping the ECU. The value might be (and probably is) available through a custom PID that can be added to RaceChrono, but you'd need to know the details on how to poll it...
