Max, thanks for the explanation about 'resetting' and 'initialising'. In the normal course of events, switching the power off and on should reset and then initialise the ECU. If it does, clearly it was having no effect on this IACV problem. So, either the Japanese forums are talking about something more complex—the equivalent of a factory restore of a phone or computer—or we're taking about upgrading the firmware. I repeat, if there is upgraded firmware to be had, it seems very strange to me that it's only available in Japan and Honda in the US hasn't heard about it.
E11even_Hunnit, if it were as simple as popping out the garage with a laptop and a plug for the connection under the left side cover, popgun and max would have figured it out years ago, or you could watch some bloke on YouTube showing you how to do it. It suggests that Don Guhl has a bit of investment either in purchased or home-made software that allows him to read ECUs and modify the settings. He has to do something to recoup the cost of that. Presumably there's also some time and care in individual attention to owners' requests to tinker with various ECU settings. Of course, it's likely I'm wrong and I look forward to your telling the forum how you figured it out. Good luck.
