The light is not the be all end all of how the ECU is working, its merely a tool. And like all things it doesnt always work good, or the same as every other ECU LED.
I doubt your ECU is bad, I am sure there is a reasonable explanation somewhere in your system. But without being there, diagnosing is hard to do.
