im stil wondering about this. the c5/cos3 software apparently has no trouble commanding an ibpw under 0.5 ms. iv seen 0.45 and am reading other people see 0.25. the latter is weird, as the offset is around 0.5 ms already. engine idles at 1.8 ms.

ibpw is the final/physical command of the ecu to the gate of the mosfet that pulls the injector down, right? the forum is full of threads where ibpw wont go under 3 ms or whatever. how come? any thoughts?
