hmmm... interesting... could it be the computer always tried twice, only during engine start, to know if its power stroke or intake stoke? The mark gear will already tell us which pair of cylinder is at the bottom and which at top. when we crank, computer will inject into a pre-pick cylinder at bottom. if its alive (means its the correct cylinder), continue with the sequence. if no go, will inject again when that same cylinder go bottom again. This way, maximum only 1 injection is lost during startup. guess once and go if correct, reset sequence if wrong. But maybe Honda engineer have a more canny way...
