This came up in another thread but I thought I'd continue the conversation here and avoid taking the other one even further off-topic.
The question is, what is the appropriate behavior of the injectors at throttle-lift.
Datalogs on my own car suggest that the injectors drop to about 1.5ms and hang there for about a second before going to 0ms for the remainder of the coast-down. It has been suggested that they're actually supposed to drop immediately to 0ms as soon as the throttle is lifted.
If you have observed one behavior or the other in your own vehicle or if you have advanced knowledge of the ECU code then please chime in.
