Thanks for those links, I read through some of them. This passage might explain what's going on with my idle problem:
"To understand the function of the hybrid, please envision it as a type of interface that converts the 5 Volt signals of the microprocessor to 12 Volts, or 12 Volt signals of the controller to the level lower 5 Volts for the microprocessor. Additional functions such as Lambda regulation, resets and reference voltages are also integrated."

All this time I have the suspiscion that the ECU goes into some sort of state it will not recover from, at least part of the time. That bit about resets and reference voltages seems to point towards that. The fact that I may have the wrong ECU for the engine may worsen the problem.

I have purchased the -949 ECU and I am awaiting delivery.
