rebuild engine EFI+EDIS ignition setting request

Hi All,

Just finished installing my rebuild 3.0 911 engine in my 69 targa. I have ITB's installed, EDIS 6, 36-1 VR and a camshaft sensor.

Everything works fine (fuel, spark etc). ECU is the MS3X, set up for sequential injection but currently set to batch firing.

I have a problem with my ignition timing. It seems that the spark is way off therefore the engine will not start at the moment (flames out of the exhaust and engine stalling during cranking because the spark ignites during the compression cycle.

I am not really sure whether my setting is correct:

Spark mode: EDIS (should this be EDIS multispark?)
Trigger angle: 60 degrees (as the sensor is 6 teeth before TDC)
Advance: 10 degrees.

Is there perhaps somebody with the same config that is willing to share his ignition settings? There must be some error in my setting but I have not been able to find it.

Help is really appreciated.

Thanks, frank
