What OBD2 protocol is used on the CB1100?

[dsinned_imp]

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.

This might help : http://www.healtech-electronics.com/products/obd/

I don't have the scanner, but at least one member here does. I do have the gear shift indicator.

When I read their product description, it says the scanner just plugs in to the diagnostic connector, which is behind the left side cover on our bikes (the Healtech GiPro gear shift indicator plugs into it too for those that don't don't know)

I was going to say something about this earlier, but I knew popgun would help. The diagnostic connector is not a 16-pin connector. I suspect it may be proprietary, but used in lots of Honda models.

From what I've read it appears they are not a pure OBD II operation. There is one guy (who wants to data log for track days) that seems to have determined that they are essentially using iso9141-2 as a base layer. He came up with an interesting solution -- though I don't know if you could mod this to work with BT to a tablet.

Hi Mate,

I use the Healtech OBD tool, plugged to the 4 pin red DTC port found on the left side cover (where the GIPro plugs in). The software is windows only. I was thinking of using a compact battery powered PC plugged in for collecting data, if I ever needed it. No screen though. I researched a lot about OBD2 with BT dongle and Android Apps before spending money on the Healtech tool.

Cheers.

You could also use a Windows tablet. I have an 8" windows tablet, which I really don't use for much at all, and I do not recommend for general tablet use, but this Healtech OBD tool might be a use.

Thanks for the feedback guys.

Wow, the Healtech OBD Tool costs $230 (free shipping), plus the cost of a Windows Tablet. That puts this out of reach of "affordability", and portability would be questionable while riding the bike, but otherwise seems like a solution.

Apparently, Honda's "DLC" connector is NOT directly OBD2 compatible nor is the datacomm protocol. I was hoping it would be like mandated in the U.S. automobile industry. My Triumph Bonneville uses the same ISO9141-2 standard OBD2 protocol AND has a 16 pin DLC just like all late model cars sold in the U.S. This allowed for a very inexpensive and completely portable solution with no other special equipment (interface adapters) required.

This company has another product called, "MM5" for $130 which might work for an "external" temp sensor application. Obviously, it is intended to be used as an OAT temperature sensor, not EOT. But, if it can be attached in direct physical contact with the CB1100's oil cooler housing - to a flat surface area either on top or bottom - and has an adequate temperature measurement range, up to 160C (or 320F), this could work.

Healtech's feature description says, " Comes with a wide range, high precision external temp sensor", but does not say what is that range. An OAT sensor really only needs to have a much narrower range than what would be necessary for engine oil. I submitted a question about this to find out. However, for the price of a simple display module that could be velcro'd just below the center LCD on the bike, it is certainly a possible workaround solution.

Remember, you're not needing massive CPU power, so you could probably pick up an older windows tablet off eBay for pennies on the dollar. There are tons of low-power tablets that run windows XP for > $100.

Yeah, you probably won't see a compatible OBD2 interface until they are mandated by the government. All of the Japanese bikes I've seen use proprietary interfaces and protocols.

I was surprised to hear that Triumph uses a standard OBD2. I suspect, as a lower volume manufacturer, they opted to use the standard interface to reduce parts costs.

Only automobiles pickups and SUV's (a/k/a light duty vehicles) are required to be OBDII compliant. http://www.arb.ca.gov/msprog/obdprog/obdprog.htm

My job, before retirement, was Environmental Regulation Compliance. I attended many ARB OBD regulation development meetings back in the day.

Now all I do is ride my CB1100 and smile.
