What OBD2 protocol is used on the CB1100?

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.
