Re: How do Atom Computer Ignition modules work?

quote jnjvan:

It is evident from Phil’s upper scope plot why points timing is important. The optimal time for the points to open is at the top of the large peak. The large peak is where the most energy will be stored in the coil. Opening the points at this moment results in the hottest spark.

Assuming that’s a current waveform, then yes, you want to fire at the highest peak – which represents the greatest dB/dT. If it’s voltage, well.. then current could be lagged up to 90′.

Still the same.. what are the chances that current peak coincides with the correct crankshaft timing angle? 😀
