Nytros,
we make ignition modules for Harley Davidson for more then
5 years . I designed the schematic and the board . I learned a lot from
my passed experience that processor pins should be 100% isolated with
optoisolater
and your board should be 4 layers with power and ground plane.
the board layout is very important for example you have 8 bit data
wires on your board whey can be next to each other I am sure you have
seen this on many boards but for automotive you should add ground
in between like first data wire then ground second data wire then
ground and so on any way I hope this will help you.
