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. |
It works! Atleast in the test bench.
I hooked the device to MPGuino, and it really counts the pulses, and looks realistic.
The MPGuino counts the injector pulse durations, but in this case it apparently counts the time how long it takes the metal piece in the flow sensor to pass the hall sensor.
Now i just need to get some pipe somewhere to install this in the car
