What we have at the moment is: BMW 325iX with stock M20B25 (inline 6 cyl) engine planned to be turbocharged, but before it the GenBoard v3.x should take its place on the car.

As I am not an electronics expert, any help from others who have successfuly managed to install Genboard on their cars will be appreciated!

As we have a spare engine, while studying / installing Genboard these changes will be made on it and later it will be installed on the car in the place of the stock engine:

Q: What parameters of coils are neccessary to know (resistance etc.)? Or is it enough?

[MembersPage/PhatBob] How many connections do the wires have? Can you get hold of the wiring schematic for the installation that has these coils as this makes working out the connection a hell of a lot easier.

I guess this is what you mean: [wiring] [coil_1] [coil_2] [coil_3] Resistance measured: primary coil: 0.7 Ohm; secondary: 7 kOhm. There are 3 connections on each COP. Weight ?

These look like very standard transformers. If they are good for inductive ignition app, GenBoard can drive them. If they are for CDI only (inductivity should be measured to know, if their datasheet is not available. Or experiment from 800 us dwell, and measure spark energy, see DummyIgnition, DwellControlIgnition).
