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?
Very frustrating.
Look for any other injector value anywhere that is 0.125 s and change it to see what happens.
Try playing around with different combinations of B4003/B4004.
You might have to try values that are not strictly read or derived from the injector datasheet.
hm, not frustrating, its great i dont have these problems. so is the need for b9021 cax limited to certain os?
