Hi All,
This is what I have heard on the issue with replacing points with a module.
Atom
Automatically adjust the ignition timing to the same firing position as the original breaker points which other electronic modules cannot do thus prevents overheating, backfiring, engine damage, etc.
Colour coding is for ignition timing.Green,Blue ,Brown,Yellow,Red,Orange,White,Purple,Pink.
Sometimes the timing is wrong without the right module.I have heard of rekeying the flywheel to get the timing right when using the wrong module.
