There are at least two optional wiring schemes for the one PicAXE
per injector EFI system.

The PicAXE could be mounted on the injector
or it could be plugged into a mother board bus located
behind the instrument panel. That would give you the option
of using one mass air flow sensor to cut about $30 each
from the PicAXE parts cost. It would also reduce a bunch
of wires floating around the engine compartment. The leaning
pot could be attached to the motor board. So too the
USB connector for the removable cockpit PC.

What do you people think ?

Here too is the Omega temperature data acquisition RS232 net work
system for the addition of EGT and other temperatures monitors.
Of course they will require one off the shelf low cost RS232 to
USB adapter as will the RS232 PicAXE's. This adapter can be mounted
on the mother board. Data display and formating is up to the PC.
