Yep, that would work but it crosses the line of too complex for
me.
My second throttle body will probably be a small carb
(chain saw type weighing a few ounces ) but I probably will not
connect fuel to it. If dual EFI controllers, dual fuel pumps and dual fuel
injectors let me down I've probably lost ignition anyway. Then I'd have to
have a backup magneto (or something like that) then an MSD spark mixer for the
plugs, then a separate fuel pump for the carb, then.... It has to stop
somewhere and I've reached my stopping point.

a $5 oil cooler?)

Tracy, I've often wondered about this :
if you're going to install a backup TB,
why not use a carb with its own independent fuel supply?
This way you'd be backing up the fuel
injection system too. Could this be made to work?

No. Although the RX-8 throttle controller will be redundant, my
strategy for fail-safe on this item is to have a separate (small) throttle
body for heated & filtered air which will allow enough power to sustain
level flight as well as taxi power. The main air inlet will be
unheated and unfiltered.

Tracy, how are you planning reversing or countering
the return spring in the throttle body.

Changed my mind again on oil cooler. Engine room on the RV-8
is coming out so nice & sanitary that I don't want to clutter it up
with the oil accumulator that I bought to damp out the pressure pulses
that could kill the evap core cooler. Also getting a little more
conservative (chicken) as I get older.
So Rusty, was that a fluidyne cooler on your -3? What
model? Looked real good.
Finished my evaluation on the RX-8 fly-by-wire throttle body
and still plan to use it. It is not as simple to use as I had
hoped and will require a custom controller to make it work. I'll
make them available to others who want to use this part.
