about Bosch L Jectronic

[collet]

Dear,
I was suprised and enjoy to see diy_efi, it doesn't exist in France.
So I will enjoy if any body can help me about the Bosch L Jectronic system.
I would like to know if an electronic schema exist or not.
On the board we can see two specific component: firt one is used for transform the 
primary signal for ignition and the other one I don't no it's like an hybrid, so by what 
can I change this two component?

Thank you
