I just got few flow meters, and i'm gonna attach them to my car soon to test how it works.
Two inexpensive flow sensors, 4011-logic-ic to make some logic to in/out flows and MPGuino.
Until now, it sounds easy, but we'll see
Now i have read the entire thread. So no real results from this idea...
Like someone said, it may be tricky to get proper reading at MPGuino. If i don't have enouh skill to modify the code, i'll make a pulse counter myself.
I actually have an electronic injection in my car, but i want to test this too, just for fun. And besides i can put two meters side to side so i can monitor how much they differ.
