Re: How do Atom Computer Ignition modules work?

That’s brilliant, thank you both. So let’s take a moment for theory-of-operation..

Correct me if I’m wrong, but this module triggers off of the rising voltage waveform induced across the ignition coil primary? I just can’t see any other way it would work – there aren’t any magnetic sensors and the old points are gone, so they can’t be used as a signal.

How could you possibly establish correct +and+ consistent ignition timing with this? Ep is a function of dB/dT, so the faster the rotor spins, the greater the voltage induced by a particular angle of rotation. If the module is set to always fire at a particular level, this would mean that the timing would advance as the engine speed increases.. and that the base timing angle is affected by things like magnet quality, rotor/stator gap, rotor magnet/coil geometry, and on.

"With Unique Timing Adjustment" is right.. So how the heck does it work? :geek:
