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:
- larger 440cc low impedance injectors (available at the moment);
- head porting, slight combustion chamber changes;
- custom inlet, outlet manifolds;
- lighter valve retainers, rods, flywheel etc.;
- turbocharger;
- ignition: got COPs from M52 (Bremi 11860)
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]

- Knock and EGT: yes;
- LCD and PS2: no;
- MAP connection: 250kPa onboard;
- primary_trigger: VR;
