guys,I have a small doubt on this thing

if I change the maps soi on edc16 on vw it also elongates the time of the injection,then in theory it would also change the timing of injection, or am I wrong?

if instead I change the maps soi on edc16 common rail injection time is anticipated, and then the injected ends before,right?

at this point, the EOI to serve if good or bad in the beginning to me the advance and the end of the from the time of injection?
