Shrinking Dwell

[PJM38]

Hello,

Oups, I forget to explain that I switched my probe in X10 for the VRin signal. The value for the green signal has to be multiplied by 10. So the tach pulse is 4v p-p and the noise around 200 mV p-p.
The mode 1 of LM1815, is adaptative. Input Arming Threshold is depending of the amplitude of the signal. For low amplitude signals, the threshold is 45mV p-p.
...It's really works. My cranking is perfect (i had previously kick-off and backfire during cranking). I test a lot of cranking in different temperature conditions and I my ghost offset advance have gone. Test on road are also very good. No tach loss, no knock, reproducible behaviour.

Join my last msq. I think it can be a good working starting point for a future 944n/a megasquirted.
