   I am working on a new EFI system based partially I what I learned using
   the TTC Motec
   system.

   It will be super easy to wire and super fast to wire. Can be wired in
   minutes and not hours,.
   This is a MAJOR breakthrough for after market EFI. Unlike all EFI
   systems on the
   market today.

   There will be an EFIS built in with all the engine parameters and
   manifold pressure.
   All data will be recorded like the Motec.
   It will be stored on a 32 Gig Micro SD card. This card can be taken out
   and read by any PC
   and most tablets and cell phones using Android. Maybe Apple but I don't have
   one to test it on. Not available on the Motec.

   The screen on the instrument panel will be of your choice. All one needs
   is a VGA
   interface.

   This is a list of the recorded and instrument panel displayed data so far.

   Manifold pressure
   Oil pressure
   Oil temperature
   Water temperature.
   Manifold air temperature.
   RPM
   Altitude. Handy for tuning.
   Air speed
   O2 rotor 1
   O2 rotor 2
   EGT rotor 1
   EGT rotor 2.

   It will control stock RX8 ignition coils. This saves money as you will
   probably have them.
   It will control stock RX8 yellow injectors. Dido.
   It will use two a stock CAS. Dido for one.

   It can handle two CAS as this is a critical part in all EFI systems.
   If this goes out the engine stops. No if ands or buts.
   So I have implemented two. One to control rotor 1 and one
   to control rotor 2. If either one goes out notification is
   shown on the cockpit screen and control reverts to the one
   good one  but but it will then control both rotors just like the stock
   system.

   More on this new EFI system later.

  Paul,
   I like your idea. Sounds better than the mega squirt I was planning to use. Any possibility on integrating a redundant processor?

Good question.  In all the years Tracy sold his redundant  system I don't recall ever hearing about a processor
failing. Tracy used a relay to select which processor controlled the injectors. That relay was a thousand times
more likely to fail than any of the electronics. When was the last time your cell phone failed? :-)

You can use two of these systems including the screens on the instrument panel.

Assume you are using two of these complete new systems.

There are at least two  ways of setting up two systems. One injector on each rotor can be controlled .
Same goes for upper and lower plugs.

If you want true redundant systems and you are using a p-port there are two injectors on each rotor,
This system will sense an injector failure and up the duty cycle on the remaining injector. Max power
will be down as an injector can only deliver so much  fuel. A notification will appear on the screen

The other way  is use one system per rotor and two screens.

Same goes for an injector failure. Injector failure or plugged injectors are the most likely
scenario.

Same goes for  O2 sensor failure. In that case the system will default to manifold
pressure control alone.

The simplest back up fuel system is the Wright Brothers system. A gravity feed tank,
a needle valve and a small hose dribbling  fuel to each rotor intake runner.
I know somebody that has tested this on an aircraft engine and it works to keep the
engine running. Assuming the ignition is still working of course.
