Title: Does this triggerlog look right? 1.8T AEB
Post by: bonden on November 30, 2017, 12:04:09 pm

Hi folks. I have setup my primary VR and secondary HALL sensor, and i have the following triggerlog. I believe the signals are ok, but still, the ignition outputs seem of.
If you could point me in the right direction for getting the correct spark timing, i would be very gratefull!  :)

This is my trigger settings, TDC after trigger is at 78 now.

What do you mean by seems of?

Can you produce a triggerlog and a vemslog of the engine cranking or running?

Hi gunni

I have the following triggerlog:

When i say it seems off, i mean that there are only one ignition/spark per 360 rotation, maybe even less. There should be 2 (im not running wasted spark) I have changed the TDC after trigger to 78 since this log was made, i might try 54 degrees (13-4 teeth, 6 degrees apart).
The engine is only cranking, not starting on this log.

The rest of the setup:

I could not get this sequiental firing to work, so i'm running without cam-sync now, and just using 2 stepper outputs, thereby running wasted spark setup, and it works like a charm now.
