I've had problems with the vapor too. I've tried many different things to prevent the Zemco counting the bubbles. Last summer I took the sensor off the car, as the hot weather + 2hr at highway resulted in a total vapour lock and the engine did not get any fuel.
Then I decided to get an electric fuel pump, Hoping it would solve vapour problems. Maybe I get it installed for next summer.
Are you using this new flow (and speed) sensor with MPGuino?
I would be interested, how have you connected the hall sensors to it?
I quess you need a few electrical components to adapt the signal for MPGino?
Any schematics?
