    I am one of those who found EFI intimidating but I always thought I
    would deal with it when the time came. However, there is almost a
    continuous thread of problems faced by other builders trying to get
    reliable performance out of the the electronic ignition and EFI
    which of course I have been reading for years. I can't exaggerate
    the relief I felt the when I decided to go to crank fired ignition
    and a carb. It was a matter of accepting my own limitations. Jerry


    Furthermore one is expected to solder 37 tiny wires on this
    connector. I would say 80% of the people on here don't have the eye
    sight,
    skill and manual dexterity required to do this let alone the
    electronic knowledge
    to trouble shoot such a system.


    I suggested years ago a simple printed circuit board adapter and screw
    type connectors but the idea was rejected out of hand.

I have 670 hours now and zero problems with [the stock] EFI. Believe it or not my
airplane engine has never been flooded. Always starts hot or cold wx,
hot or cold engine.

Well you don't have an RX8 engine either :)

I think Perry has a good point; a well engineered EFI should be easier to
maintain, and superior in all respects except power consumption.

I am concerned that builders will give up on EFI out of hand after hearing
about the problems people have encountered.

I am actively working on the super simple low pressure dribble fuel
injection system Paul suggested some time ago. My design goal is to deal
with all the problems encountered so far, including power consumption. It
will use a nano-power micro controller. The low pressure means that not a
lot of power will be used by the pump. And the low pressure means a
(somewhat) safer system.

I am considering publishing a progress report. If anyone is interested, I
will; if not I won't bother.

I am definitely interested.
