Rone Kenoby wrote:why not, so if i understand your mind, each injector is fired two times per cycle :
- the first one when the piston is at top dead center before power
- a second one when the piston is at top dead center before inlet
we agree with that ?
Correct
Rone Kenoby wrote:and to bounce on a previous topic, at what moment exactly is fired the injector during engine cycle : at TDC time or at tooth number 1 (equal to 90°crk before tdc power)

i suppose at tdc ?
One of those two, but I didn't write the code. Without checking, I can't confirm either way.
