Thanks Steve
Rather than reroute the fuel lines I think I=E2=80=99ll build a little =
processor and measure pulse widths and rpm and create a pulse stream fr =
the dynon to read.
Any hints on anything to watch out for in coding?
Cheers

Steve

>>> Just about any fuel flow instrument will work, if you design the =

Tracy has this fuel delivery architecture in the RV-8 3-rotor.
