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 injectors (obviously high impedance);
- head porting, slight combustion chamber changes;
- custom inlet, outlet manifolds;
- lighter valve retainers, rods, flywheel etc.;
- turbocharger;
- ignition: [COPs] from BMW M52 engine
Shopping cart:
- 1 x Assembled v3.3 controller
- ignition driver: 6+2; (this means 6 power "IGBT" outputs, 6 of which you apparently plan to use; and 2 logic-level - these will be unused)
- Knock and EGT: yes;
- LCD and PS2: yes;
- MAP connection: 250kPa onboard;
- Power Flyback: yes;
- primary_trigger: VR;
- secondary_trigger: Auditrigger;
- 1 x EC36-harness
- 1 x EC18-harness
- 1 x Wideband O2 sensor
- 1 x WBO2 connector with crimped wires
- 1 x EGT sensor
Received GenBoard some time ago. Finally managed to work on it last weekend.
Firmware is uploaded. First tests have been done outside the car: managed to get MAP and coolant temperature readings. Next step will be installation of genboard inside the car and wirig all the sensors, injectors (still on their way) and COPs. Now searching for POT style TPS.
