Hi

It is possible to have injectors DC above 100%? For eg. 130%?
I ask because i have that measure but my AFR isn't lean is rich as desired.
Everything is in the attachment.

The injector DC is relative to what window of time? The full 4 strokes (2 crank revolutions) or the intake valve open time window?

ECUxPlot already divides DC by 2, so that is 100% over *two cycles*

So yes, anything over 95% as displayed in ECUxPlot is injector wide open.

Not sure about that graph, he should be going lean up top.
