quote wrote:4 intake events on a 4 cylinder? or 4 measured over a period of time? if they are measured over a period of time without a clock, how do you know how much air you have? At that point you have an instantaneous signal that says "event occurring" and an instantaneous voltage measurement that relates to airflow RATE but no idea how long between events and therefore how long the air has been flowing at that RATE and therefore how much air you are swallowing.
Relating to digital processing, I have a question about this, Fred. An extension of the 'Minimum Sensors' thread in the Hardware forum.
You were talking about needing RPM, and I was talking about digital/linear processing. (Which is either an infinitely large or infinitely small clock period.) So we were on different pages maybe, you and I.
The question is: Are you planning to process the MAF and MAP signals in the same way? From the quote above it seems like it's possible that you might be.
