The car is a BMW Bavaria 3.0S from 1976, chassis model is E3.
Below are details on the install of a VEMS Genboard on the engine.
Engine information
- Stock M30B30, a 3.0 litre inline 6 cyl, about 180 hp with stock carburators
- 6 x 380 cc/min fuel injectors, high impedance from E34 M5
- Stock distributor ignition
- Stock coolant temperature sensor is ok for use with the Genboard
- Potentiometer style TPS (got it from Farnell)
- Custom intake air temperature (IAT) sensor mounted just after the throttle plate, sensor is NTC from web shop
Plans for Genboard control
Custom harness
- Electric fan
- Idle air solenoid
- Sequential fuel injection
Trigger setup
60-2 wheel from a modern M30 (BMW E34 535 -91) with stock VR sensor.
Genboard configuration
To come.
Q: Are these MSD p/n 8224 "GM 2-Tower Coil Pack" ok to use with the IGBTs ?
http://www.msdignition.com/coil_blaster_9_8224.htm
Their low resistance (0.35 Ohms) suggests a high flyback voltage. Can the IGBTs handle that?
According to the PDF instructions they can be used for stock replacement on some vehicles, in some cases using ballast resistors, and ultimately the MSD DIS-4 CDI unit is suggested. Pure CDI coils typically have much lower resistance (<0.01 Ohm), this is a half-breed. Will it work as a regular inductive coil?
