Nice information, let me help decipher some of them ...
As per your data list, I am just wondering why the reading is the following:
Why the "ECT" (Engine Coolant Temperature) reading is displayed instead of the "EOT" (Engine Oil Temperature) which the CB1100 is using?
For the idling complaint issues:
Keep in mind for future reference that at regular idling speed with the Throttle position at 0 (Tp = 0):
at idling speed of 1121 RPM, the ECT of 253 deg.,IAT of 78 Deg., the IACV valve count is at 34 steps.
at idling speed of 1074 RPM, the ECT of 197 deg, IAT of 71 Deg., the IACV valve count is at 39 steps.
From your KOEO ((Key On, Engine Off) data I was wrong in one of my previous comments under a different blog, I did mentioned that with the KOEO the IACV reading should be at 125 steps - your picture that it is at 99 steps.
Also, can you post a graphic view (let's say 10 seconds) of some selected data instead of just line data? (selected data of Idle speed, ECT, IAT and IACV?
FYI, the "Graph" information is more helpful since it shows information during a selected time period instead of just that "one" instant.
To make it easier to understand, it is explained like this ... Graph information is like you are watching a full movie (with thousands of frames) compared to line data which is "looking" only at "one" specific frame. - I am not sure whether I explained myself properly.
The MAP information, is it possible to change from "PSIG" value to let's say Inch of mercury absolute?
Also, the ST and LT Fuel trim is at 1.0 which means that your engine is running at perfect stoichiometric - not too lean or not too rich - there is no ECM correction required.
I should buy that OBD2 adaptor for my CB to play with.

Alain
