for injectors and idle / boost valves i`ll be using vnld5090, but is there something similar that can be used for ignition ?

Flood with copper but remember copper flood isn't a ground plane unless its designed to be.

ok, can you explain this idea a bit more ? Untill now, i have not connected any ground pin to each other. It was my understanding that you can just flood it and it will be ok, and if nececery create vias to connect difficult areas.
am i wrong about this ?

You need to lay out the traces in such a way that the copper flood and tracking allow a continuous, direct, path from the component connection back to the 0V pin. You can tie isolated areas together with multiple vias but it adds inductance into the path.
