What OBD2 protocol is used on the CB1100?
#1



Does anyone know if the ECU is OBD2 compliant and to which standard protocol (e.g. ISO-xxxx)? Does it have a 16 pin OBD2 connector interface and if so, where is it?

What I want to do is attach and OBD2 dongle with either Bluetooth or WiFi and monitor PIDs with an app like TORQUE. The parameter of most interest is engine temperature, which is probably based on the existing EOT sensor.

I successfully did the same thing to my late model (EFI) Triumph Bonneville by handlebar mounting an Android 7" tablet. I did this primarily to monitor EOT of my oil/air cooled engine and a few other parameters, including instantaneous and average MPGs, which are actually calculated by the app. (The 2014 CB1100 center LCD already can do the latter, but there is no digital readout for EOT, just an idiot light.)

I can display up to eight virtual "gauges" of information on the app's dashboard, even HP and TQ, and others like IAT, MAP, MAF, as well as "Boost" for an OEM turbocharger. This can be safely and easily be done (while riding), and I already have the aforementioned OBD2 BT Adapter dongle and a companion app from ScanTool.net that works flawlessly on my Triumph.

I just need to know the specific OBD2 "standard" protocol HONDA is using on this bike. The adapter can do an automatic protocol determination, "if" the ECU supports the OBD2 standard, or by chance does HONDA use something proprietary. If proprietary, then this probably won't work.

Again, I am mainly interested in monitoring oil temperature (and pressure) since the bike already has sensors for those parameters.
