Well, then correct him. If he is wrong that's alright and we all learn something. If not you just a barrel of ......................(insert your own word here).
OK I deserved that...maybe I should explain my position
pickup/stator generates signal to ICM.
In crank ICM generates signal to coil on its own.
using the pip, the ICM does not generate a pip
ICM then generates PIP SIGNAL that is sent to ECM,
using the pip, the ICM does not generate a pip, the pip is solely generated by the hall effect sensor then thru the icm
when PIP signal is above certain RPM in crank/start is attained that PIP info tells the ECM to fire the injectors,
Actually the logic inside the pcm uses the pip and crank signal to start pulsing injectors at any rpm, at above a pre determined rpm (I think its 500 rpm) the ecm starts to calculate spark angle - timing - but injector are already firing, but this is admittedly splitting hairs on my part.
and generate a SPOUT signal to control spark VIA the ICM.
just to clarify, the icm does not generate a spout, the spout is an output from the ecm to the icm, the spout is a computer controlled strategy the icm just fires the coil when signaled, the is no logic inside a icm.
You can have spark in crank without ECM firing injectors.
Hence the WOT NO start or used in flooded starts.
WOT fuel cutout was used in the first couple years of injection, Ford as most manufactures altered this strategy for a more controlled unflooding , I am not sure when. This is a function of the ecm logic that has nothing to do with the icm or pip
You can have spark without PIP signal.
its known as a bypass ignition.
The ignition bypass, as I know it, is a GM function
My response is only meant as way of telling my beliefs, and in no way do I want to come off as a "know it all" Its hard to show a demeanor when posting.
