fuel flow sensor

Noah;

Ok then. Lets say the small line comming off the spider is the analog fuel flow / fuel pressure, what would the line comming off the fuel pressure port on the throttle body go to? That line was also present on my engine.

I am familiar with the digital sensors, the one you picture is the "red cube", I have a Floscan 201 that I plan to use. I just want to know what to do with the other lines. I guess I just plug the gage port on the spider and the fuel pressure port on the RSA throttle body??

Yes, the fuel flow port on the spider is plugged if you're using an inline flow gauge like the floscan. I need to look at my RSA5 servo to see what port you're referring to, but it sounds like the other port is for fuel pressure at the servo inlet, which would run to a gauge or a pressure sensor - whereas the Vans typical location is to tee off the outlet of the mechanical fuel pump for pressure indication.

Harry,
I must say I'm impressed with your microprocessor skills.
However, I'm sure your Dynon will have the facility to scale the fuel flow after you have established the actual flow rate. GRT certainly does.

Might pay to check the Dynon manual.
