In this screen shot the line graph, I've stretched out so you can view a full 10 seconds of run time.
At the far left the narrowbands start out well over 900 mv. The trims, at the same time, are nearly pegged positive.
The far right of the line graph, a full 10 seconds later, the narrowbands are 948 and 800 respectively, and the trims are still +38 and +15.
If you think that's proper injector control at low speeds, the rest of the conversation is moot.
