How to get secondary trigger from distributor ignition?

Post by bmwmaster » Thu Aug 04, 2016 11:02 pm

My engine has an single coil distributor ignition. It has an Induction sensor on ignition cable of zylinder no. 6.
Is it possible to use this signal for secondary trigger?

I cant get the right settings for it. I can measure an signal which comes from the sensor with osciloscope but its about 300V high but very short.
Have connected this to pin 15 camsync 1.

If it's 300V, I really wouldn't connect it to the EMU.
I'm wondering why is the sensor on the cable and not in the distributor.
Is it an electronic distributor? Or a mechanical one with a simple switch?

Every electronic distributor I've seen on an oscilloscope, the sensor was outputting a signal somewhere +- 12V... or +-5V.
I think you can use the distributor sensor as a camsync if you remove all but one of the magnets. But you can't use it as a distributor anymore...
But why would you, if you have the EMU :)

The sensor is not placed kn the distributor itself. Its a ring which is mounted on the ignition cable of cylinder no. 6. I think its an induxtion sensor which gives an signal when spark is fired. So its taking its signal from some thousand volts and sending a very short about 300v signal out. In original this signal also goes to oem ecu and i thing its necessary because ecu this way knows in which cycle it is and inject fuel at the right time.
Now im running the engine without camsync and think sometimes its not in the right cycle. And injecting at the opposite cycle. I could try the squirt twice funktion but would prefer to have a right solution.
