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] [coil_1] [coil_2] [coil_3] Resistance measured: primary coil: 0.7 Ohm; secondary: 7 kOhm. There are 3 connections on each COP.

Q: Can GenBoard manage these coils?

Shopping cart:

1 x Assembled v3.3 controller
- ignition driver: 6+2; (this means 6 power outputs, 3 or 6 of which you apparently plan to use; and 2 logic-level - these will be unused)
- Knock and EGT: yes;
- LCD and PS2: no;
- MAP connection: 250kPa onboard;
- primary_trigger: VR;
- secondary_trigger: HALL input should be fine, usually not used for this engine
1 x EC36-harness
1 x EC18-harness
1 x Wideband O2 sensor
- 1 x WBO2 connector
1 x EGT sensor would come handy

Q: What else is needed?
