Lambchops i am happy to say i was wrong with most of my previous post, this looks like the real deal.
Thanks very much for the link and your hard work, it does point in the right direction.
The webpage is in japanese so i copied and paste all the relevant descriptions in google translate and here are the results with regard to the cb1100 reset.
Mcs means; Honda "Motorcycle Communication System"
ecu means; "Engine Control Unit"
pgm-fi means; "Programmed Fuel Injection" system ( Honda proprietary name )
I think it may be a good idea if wisedrum could copy these pictures and show them to his dealer to compare if they are the same.

CB1100 ECU update
I was informed that "I will stall if low speed driving continues in a traffic jam".
( max; connecting ecu to cb1100 with battery and pc cable connected ( to k line 0 to 12v serial bi-directional data stream ) )
ＣＢ１１００ ＥＣＵアップデート
「渋滞中の低速走行が続くとエンストする」とご相談いただきました。
アイドリング付近の回転で、発進・停止を繰り返すとＥＣＵの指示と、
ＩＡＣＶの作動にアンマッチが起こるようです！
アンマッチ発生時、IACVが徐々に閉じる方向へ作動し、供給空気が不足した状態になりエンストに至る場合があるようです。
対策のため、ＥＣＵのプログラムを書き換えします！

Means;
When starting and stopping are repeated with rotation near idling, the instruction from the ECU
There seems to be an unmatch in the operation of IACV!
It seems that when an unmatch occurs, the IACV gradually operates in the closing direction, causing a shortage of supply air and leading to an engine stall.
As a countermeasure, rewrite the ECU program!

( max; "connecting to ecu and retrieving software version" )
( max; software and vin nr found with option to update to later version )
( max; ecu update in progress. )
「Ｋ様」これで、暫く様子を見てみましょう。

"K-sama" Let's take a look at this for a while.
THE END.
Maybe an affected owner could present these pictures to his dealer and point him in the right direction?
From the update picture it appears the software upgrade is number; 38770-mcg -d43 -M1.rwf
Hope this helps to evolve our quest for the solution. ones and zero's to the rescue.
