In general, you can't just connect 2 computers to your
injectors, the one that is "off" will still conduct current
in some situations. Anyway, a failed injector driver
could defeat attempts of the backup to take control.
Systems CAN be designed to operate as you desire.
Short of a custom dual unit, I suggest you use a relay
to switch over the injector wires to the backup when
it is powered up. Another way is just have a second
set of injectors.
