Re: How do Atom Computer Ignition modules work?

Thanks for sharing it here. According to me 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.
