It is coming along. I am looking for volunteers to try it out.

The EFI part and ignition are totally controlled by hardware.
There is no computer faster than hardware.

The CPU's main job is to display and record  engine parameters and other stuff
on a small VGA color display on the instrument panel.

The engine will still run if the CPU stops. In fact one can have
dozens pf programs stored in the memory and one can actually change
programs in the air. All the programs are open source and can
be attached to email. The memory is 32 Gig so many  hours of flight
can be recorded.

It is all contained in a 6 by 6 by 2 inch extruded aluminum box.

The ignition must be CD or Lamar instruments. It will work with
several CD system the very popular  MSD is one of the them.

The Crank Angle Sensor is stock Mazda. You can set the advance by
adjusting the angular position of the CAS. Simple.

It is not suitable for use in cars as aircraft engines run for long periods of  time
at the same power level.
