Hi all. I'm new to the forum, and a new RV7a builder although I have 41 years in aviation. Most of my time has been in Avionics and turbine aircraft.
I have a IO-360-A1B6 and have a question how to route the fuel return line from the distribution spider. Does it take a special valve to route the return fuel back to the tank it came from?
Next, the fuel flow sensor(s). I am planning the Dynon EMS with fuel flow. I am aware of the Matronics adapter that uses a sensor in the main and return fuel flow lines and outputs the single signal to the receiving fuel flow computer.
Now, being cheap and somewhat inventive, I designed my own adapter. It is simply a microprocessor that takes the main sensor and subtracts one pulse for every return fuel pulse it receives and outputs a open collector signal for the receiving electronics.
I have the engine and have completed the empenage and am waiting for the wings. I move pretty fast with the construction, but I doubt that I will be running the engine on the airframe in the next 12 months. I have tested this unit electronically, but would like to see if anyone out there would be interested in receiving a free unit to help test this. This is available for experimental aircraft only.
I am looking for someone who is already flying. I have 3 units available. When I figure out how to post a picture I will.
